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.
