Weather Summary Autumn - September October November 2018 (2nd December)

Autumn was slightly wetter than average, mainly due to the wet November, with around 280mm of rain compared to average of 240mm. Despite this there were slightly fewer days with 1mm of rain or more (26 versus 33). The temperature average was 12.5C and sunshine hours 355 both of which are very close to the long term seasonal average.


Weather Summary November 2018 (2nd December)

Low pressure dominated the weather patterns during November but a weak ridge of higher pressure followed rain on the 1st and led to a frosty start on the 2nd. This turned out to be the coldest morning of the month for most of the district, although many areas near the coast and estuary escaped an air frost. The ridge of higher pressure did not last as Atlantic weather systems swept in across Devon and Cornwall bringing milder temperatures, as well as wet and at times windy weather. There were several periods of heavy rain, notably on the 4th, between the 6th and 11th, 23rd to 25th and 27th to 29th which resulted in rainfall totals being around double the average for November. For a time, around the middle of the month, higher pressure brought temporary drier interludes but also rather chilly winds from an easterly point. For much of the month, however, milder south or southwest winds predominated.

In terms of statistics:
The temperature for November was up to a degree above the long term average of 9.3 Celsius mostly due to the average night time temperature being about half a degree warmer due to cloudy skies and windy weather. The highest temperature, typically around 14 or 15 Celsius, occurred in most places on the 28th although some places had similar values early in the month. The coldest morning was on the 2nd with areas near the coast ad estuaries dipping to around 1 Celsius but only a short way inland, for example inland Dawlish, recorded temperatures down to minus 0.4 Celsius. The lowest recorded value was as usual in Netherton with minimum of minus 3.2 Celsius. Across the district most places had at least 2 nights with ground frost and possibly as many as 8 in the colder locations.
It was a wet month with only around 10 days with no measurable rain. There were at least 15 days when 1 mm or more of rain was recorded, the average is 12 days. There were at least 4 days with 10mm or more and 3 days with over 20mm. The wettest days was on the 9th. Rainfall totals for the month were between 120 and 200mm well above the Teignmouth average of 89mm.
Sunshine recorded at Teignmouth was 55.5 hours which was well below.

In summary, November 2018 was much wetter, milder, cloudier and probably windier than average.

Weather Summary October 2018 (1st November)

The main theme for October was one of higher than average pressure which was located near and at times over the south of England. The higher pressure resulted in a drier and sunnier than average month. The high pressure was interrupted by a series of weak weather fronts but between the 10th and 15th low pressure took control bringing rain and strong winds. This was especially so on the 12th and 13th when storm Callum was close enough to bring heavy rain and gale strength winds across the district. During the last week or so, high pressure moved west allowing colder northerly winds to develop. This was reinforced by low pressure moving east over Scotland which brought much colder air south over the UK leading to a number of frosts in the district with snow as far south as the Welsh Mountains.

In terms of statistics:
The temperature for October was close to long term average of 12 Celsius. Average day time maximum temperatures were a little above normal but the night minima were slightly lower. The highest temperature, typically between 20 and 22 Celsius, occurred in most places on the 3rd although some places had similar values on a few other days in the first half of the month. The coldest nights were at the end of the month with values around zero near the coast but typically minus 1 or minus 2 Celsius elsewhere. The typically colder Netherton area got as low as minus 4 Celsius on the 30th. Across the district most places had 2 and in p[laces up to 5 nights with ground frost.
There were around 19 days with no measurable rain. There were between 6 to 10 days with 1 mm or more of rain recorded, which is fewer than the average of 12 days. Rainfall totals for the month were between 44 and 66 mm, which compares to the Teignmouth average of 94mm. The main wet spell was between the 10th and 14th with the wetter day being the 12th when between 15 and 30mm of rain was recorded across the district. Almost three quarters of the month rain fell during this wet spell but overall rainfall was well below the long term average.
Sunshine recorded at Teignmouth was 138 hours which is about 28 hours more than the average.

In summary, October 2018 was a good bit drier and sunnier but with near normal temperatures and possibly a few more frosts than normal.

Weather Summary September 2018 (updated 19 October)

For the Teignmouth and Dawlish area the main theme for the month was one of higher than average pressure. This meant that although there were a number of weather fronts crossing the area they were mostly fairly weak with the first ten days of the month seeing no recorded rainfall. An exception was the period 16th to 23rd which was unsettled, at times windy and during which most of the rain fell. This wetter period was associated with; the remains of hurricane Helene which moved north across the Irish Sea, a named storm Ali which mostly affected northern parts of the UK, and Bronagh on the 20th which was the second named storm of September. The wettest day was the 22nd when around and inch or so of rain fell in many places although in some places the 20th was a close second.
In terms of statistics the temperature for September was close to long term average of 15 Celsius. The highest temperature, around 25 Celsius, was recorded on the 3rd or in some places on the 9th. The coldest morning was near the end of the month, typically on the 25th with values between 3 and 6 Celsius although Netherton got as low as 0.6 Celsius on both the 25th and 27th. Typically day max temperatures were slightly above average and night minimum a little below the long term average.
There were around 21 days with no measurable rain and 7 days with 1 mm or more of rain which is slightly less than the average of 9 days. Totals for the month were between 35 to 65 mm which compares to the Teignmouth average of 57mm. (Teignmouth 58mm).
Sunshine was near the average.

In summary, September 2018 was slightly warmer by day and slightly cooler by night with below average wet days.

Weather Summary August 2018 (updated 2 September)

August was a little warmer than average despite being changeable. There was high pressure at the start, for a time in the middle and also at the end of the month which led to August being a little drier than average. An especially changeable period between the 7th and 13th included the wettest day of the month which saw around an inch of rain in places on the 12th. The remains of tropical storm Ernesto moved over Ireland and then the North of England around the 19th and colder NW winds were a feature of the 24th and 25th. Low pressure was also a feature of the Bank Holiday weekend with cool and wet weather especially on Sunday the 26th.

In terms of statistics the average temperature for August was near 18 Celsius, just a little above the long term average. The highest temperature was on the 4th with recorded values in the high 20’s Celsius.

Weather Summary July 2018 (updated 3 August)

High pressure brought a good deal of fine, dry and very warm or hot weather across the district during July but there were periods when low pressure close to SW England brought some spells of showery or thundery rain. These included periods at the start of the month, the 12th, 21st and at the end of the month when some very helpful rain occurred filling up the otherwise depleted gardeners water butts. During the summer month rainfall tends to evaporate quickly and does little to ease the very dry soils across the district.

In terms of statistics the average temperature for July was near 20 Celsius, two to three degrees above normal the average. The highest temperature was mostly around 31 Celsius on the 8th and the lowest values were near between 9 and 13 Celsius occurring in most places around the middle of the month. The sea temperature measured offshore at Dawlish reached a warm 19 Celsius before easing back in the windy and wet spell during the last weekend of the month.

There were around 21 days with no measurable rain with totals ranging from 35mm in Exminster to between 50 and 60mm in the Teignmouth and Dawlish area, which is about average for July. Despite the dry days there were between 6 and 8 Days with 1mm of rain or more which is average for July. Sunshine was over 50 hours above average with 276 hours of recorded sunshine.

Averages based on Teignmouth 1981 to 2010.

In summary, July 2018 was much warmer and sunnier than average but with an average number of wet days and near average rainfall.

Weather Summary June 2018 (updated 3 July)

An exceptionally dry (and warm) June, with some people suggesting that in parts of England it could be the driest June for centuries, although we will need to wait for the full Met Office figures to be available to confirm this.

The first third of the month was largely dry and saw easterly winds across southern England due to high pressure to the north and lower pressure over France. Low pressure replaced the high across the north brining weak Atlantic frontal systems and westerly winds for a period from the 14th to 20th but apart from some patchy light rain or drizzle, the essentially dry weather continued. Following this, high pressure built over the UK returning mostly easterly winds across SW England for the remainder of the month.
In terms of statistics the average temperature for June was 17 Celsius, two degrees above normal the average of the daily maximum temperature was between 20 and 23 Celsius with the warmest day being the 28th or 29th when temperatures reached between 25 Celsius in Teignmouth (near the coast) 27 to 30 Celsius in Netherton, Dawlish and Exminster for example. The coolest night was the 22nd when temperatures dipped to 6 Celsius but in general the average of the night min temperatures was near normal at 12 Celsius.
Many places had as many 28 dry days during June. There were less than four days with recorded rain and totals for the month in Teignmouth and totals for the month were mostly below 0.5mm. Exminster area, however, recorded 4 or 5mm of rain on the 1st of June but nothing thereafter. Most figures quoted here use 00-24hour time periods but in the official record for Teignmouth rainfall is measured from 0900 to 0900GMT and will show 2.6mm for the month but 2.2mm of the total fell on the morning of the 1st of July but is included in the June total.
There were almost 240 hours of sunshine recorded which is about 11 hours above average.

In summary, June 2018 was exceptionally dry and unusually warm with above average sunshine.

Weather Summary May 2018 (updated 3 June)

The month started with a run of cooler westerly winds as weather fronts moved in from the Atlantic. High pressure in the south made these fronts quite weak keeping rainfall fairly light. By the middle of the month High pressure dominated the weather pattern over the UK bringing easterly winds to many parts. In previous months easterly winds were quite cold but with continental Europe now much warmer the easterly winds brought milder weather than would have been the case with west winds from the Atlantic. Low pressure to the south edged northwards at times bringing spells of thundery rain northwards, much of which missed the local area until the last few days of the month. Another feature of the easterly winds later in the month was a return of low cloud and coastal mist and drizzle.
According to the Met Office, the average daily maximum temperature for the UK was 17.0 °C making it the warmest May in the UK in a series of records stretching back to 1910. For Teignmouth the average maximum was 17.9°C which was over two degrees above the long term average. Across the Teignmouth and Dawlish area generally temperatures were well above average by day, though night minimum temperatures were only slightly above average. Only Netherton recorded a frost and the warmest day was the 28th when the temperature rose 24 Celsius near the coast to around 28 Celsius 82 Fahrenheit inland.
Rainfall was well below average with between 20 and 40mm of rain which fell on about 6 days during the month, the wettest being overnight 29th into 30th when thunderstorms help lift rainfall totals to around 12 mm. There were no fewer than 22 dry days.
There were 218 hours of sunshine recorded at Teignmouth which is about average for May.

In summary, May 2018 was unusually dry and warm but with about average sunshine.

Weather Summary April 2018 (updated 2 May)

April is often known for showers and typically frequent west or northwest winds. This was not the case for April 2018 which followed March in being very unsettled, dominated by low pressure and more frequent winds between the Southwest and East than a typical April. There were at least three significant low pressure areas that crossed SW England during the 1st 4th and 27th. Despite short lived ridges of higher pressure in the second half of the month the area only managed two periods of three consecutive days when there was no rain, namely the 12 to 14th and 18 to 20th. In fact rainfall was almost double the average and the total for the month was over 100mm. There were around 14 days with rain and 13 days with no measureable rain during the month and unusually 3 or 4 days when rainfall totals were over 10mm.
Given a wet month, it is not surprising to find that it was often rather cloudy with sunshine hours over 50 hours or 30% below normal. The increased cloud also resulted in milder nights with the average minimum temperature almost two degrees above normal helping the average temperature for the month to be around 1 degree above the 1981 to 2010 long term average. The coldest night was the 5th with minimum values across the area between 2 and 4 Celsius with the coldest spot as usual being Netherton with a temperature of zero. In general, frost and ground frost were much less frequent than normal. The warmest days were around the 18th to 20th when temperature in the low to mid twenties Celsius were measured. This warmer spell ended with a period of thunderstorms on the 21st.
For parts of southern England the warm spell was the warmest since 1949 and for the 19th of April possibly the warmest day for that date since 1772!

In summary, April 2018 was milder but cloudier and much wetter than average.

Weather Summary March 2018 (updated 2 April)

March was a very unsettled month with Low Pressure dominating the weather patterns across the United Kingdom. In addition, there were two periods of snow across SW England which is very unusual. The month started with storm Emma, named by the Portuguese Met Office, moving towards the SW of England and pushing up against the colder easterly, known as the “Beast from the East”. This was a perfect snow set up resulting in widespread significant snow over SW England during the first and second days of the month. Snow depths of between 10 and 20 cm were reported. Many places also had a period of freezing rain in the early hours of the 2nd which led to power failures in places. Strong winds associated with Emma caused drifting snow across higher ground, and around the coast the wind combined with high spring tides resulting in damage to the rail line at Dawlish.
Subsequently, Low Pressure and associated fronts brought less cold weather but with periods of heavy rain. From the 17th, High Pressure extending from Scandinavia brought a return of very cold easterly winds in what was called by the media “the mini Beast from the East”. This led to another 10 to 20cm of snow between the 17th and 19th along with drifting snow for some hilly areas which caused blocked roads. High Pressure and drier brighter weather followed for a few days before more wet weather spread from the west returning the unsettled weather after the 22nd. Even at the end of the month the weather was cold enough for snow over the moors but elsewhere was mainly rain.
In terms of statistics, it was a cold month with an average temperature of 6 Celsius, that’s two degrees below the long term average. The coldest morning was on the first, when temperature fell to minus 4 Celsius widely across the area and remained mostly below freezing all day. There were at least four nights with air temperatures below freezing and as many as eight for places away from the coast. In Netherton an incredible fourteen frosts were recorded which compares to the long term average for Teignmouth of only one frost in a more typical March. There were some less cold days with temperatures around 13 Celsius on the 10th and 11th and the warmest day was probably the 25th when parts of Dawlish and Exminster recorded 15 Celsius. For the UK as a whole March 2018 was probably the third coldest in the last 30 years.
Rainfall measurements during snow can be a problem but looking at the water equivalent and adding this to the normal rainfall brings rainfall totals to between 170mm and 250mm for the month. This was around three times more rainfall than an average March. There were at least eighteen wet days and only seven dry ones, the wettest day being the 9th with around 28mm of rain.
There were 88 hours of sunshine recorded at Teignmouth, that’s about 34 hours less sunshine than the average for March.
In summary, March 2018 was much colder, cloudier and wetter than average and unusually there were two periods of significant snowfall.

Weather Summary February 2018 (updated 3 March)

The month started with a series of weather fronts crossing the country bringing changeable and rather chilly weather, often with winds from the Northwest. A short period of High Pressure starting on the 5th brought some drier but still rather chilly weather but with some sunshine. Weather fronts moving in from the west introduced around ten days of milder weather but with rain at times. After the 20th High Pressure again took control introducing increasingly cold easterly winds. This culminated in what the media called “the Beast from the East” which as the High Pressure started to give way brought snow to Eastern parts of the UK and just a little snow for us to end the month. The main snow event for the Teignmouth and Dawlish area held off until the first day of Meteorological Spring at the start of March.
In terms of statistics, it was a cold month with an average temperature of 4 Celsius, that’s over a degree below the long term average. The coldest morning was on the last day of February with between minus five and minus six Celsius recorded quite widely. The temperature remained well below freezing all day making it one of the coldest late February days on record. Although the Coastwatch site at Teignmouth did not record an air frost, Teignmouth Den had 5 and in general the number of frosts was well above average. Dawlish had 7 air frosts, Exminster 13, Ashcomble 16 and Netherton 17. The warmest day occurred on the 19th when many places reached 13 Celsius..
Due to the two periods when High Pressure dominated the weather, rainfall was only two thirds of the long term average and most places recorded between 35 to 50mm. There were at least 15 days with no measurable rain and less than normal “wet” days.
Sunshine was mostly above normal across SW England with Teignmouth recording 117.5 hours that's over thirty hours of sunshine above normal.

In summary, February 2018 was sunnier, much colder and drier than average but with no lying snow.

Weather Summary January 2018 (updated 2 February)

The weather during January turned out to be very changeable, fairly windy and quite mild. During the second week of the month there were short periods when High pressure took control, bringing drier weather and chilly NE or E winds but for the most part, Low pressure dominated the weather patterns. There were four named storms that crossed parts of the UK, Eleanor, Fionn, David and Geogina bringing spells of windy weather. Most were named by the Irish Weather Service in collaboration with the Met Office but storm David was given a name by the French Weather Service which is why it did not follow alphabetically in the sequence. None of the named storms came close to SW England although the associated strong winds did extend over the region.
In terms of statistics, the average temperature was between 7 and 8 Celsius which was almost a degree above the long term average. The highest temperature, close to 14 Celsius, occurred on the 28th for most of the district although the 4th was also a contender for the mildest day. The coldest morning was on the 30th although the 7th and 12th were also rather chilly in places. Some parts of Teignmouth and Dawlish, mostly close to the coast, did not record any air frosts but elsewhere many places recorded two or three mornings when the temperature fell below freezing. Lows of minus one or minus two Celsius were recorded although Nertherton recorded minus three point five Celsius and a total of five air frosts.
In keeping with the unsettled theme, January was quite wet in places and despite some snow over Dartmoor there was no lying snow for the Teignmouth and Dawlish area. Rainfall totals in towards the coast in Teignmouth and Holcombe were slightly below average but in the main rainfall was close to or a little above the January average of 95mm. Is was notable that there were only about 6 dry days and three times as many wet days, so it will not come as a surprise that the month was cloudier than average with only 55 hours of sunshine recorded in Teignmouth.

In summary, January 2018 was wetter (rain days), milder and cloudier than average.
