Weather Summary Summer (June July August 2017) 2017

Summer 2017, although being billed as a wet summer with around 100mm more rain than average, the number of dry days was almost double the number of “wet days” and was very much in line with the long term average. The conclusion is that although there were no more wet days than in an average summer, when it did rain the rain was heavier. One other notable feature was the much lower than average sunshine implying cloudier than average skies. This should have led to much cooler day time temperatures whereas in fact temperatures where close to average.

Teignmouth Den.  Mean temperature 16.7C (LTA 16.8). Average Max 20.4C (LTA 20.6). Average min 13.1C (LTA 13).

Total rain 242.2mm (LTA 150.1). 53 dry days (LTA range 42 to 62). 28 days with 1mm or more. Total sun 525.57* hours (LTA 656.8).

Weather Summary August 2017

Low pressure dominated the weather patterns throughout August with only short intervening weak ridges of higher pressure. Most of the drier intervals were sort lived but there was almost a week of drier weather which started on the 22nd and lasted into the Bank Holiday weekend. The sunniest day was on the 13th when 13.4 hours of sunshine was recorded at Teignmouth. Judging by the total sunshine for the month, of 122 hours, compared to an average of 209 hours, the month was a good bit cloudier than we might have liked.
Despite the cloud there were seventeen days when the temperature reached at least 20 degrees Celsius. The warmest day was on the 27th when the temperature reached 28 Celsius inland but was held back to 22 Celsius near the coast at Teignmouth. The mean value for the month was 17 Celsius which is only a fraction below the long term average.
Rainfall totals were around 60mm for the month, in most places, although the Teignmouth rainfall of 41mm was below the long term average of 54mm. There were around 10 days with 1mm or more of rain, typically known as “wet days” but also 16 days with no measureable rain which was close to the average for August.

In summary August was cloudier than normal but rainfall and temperatures were similar to the long term average.

Teignmouth Den.  Mean temperature 16.7C (LTA 17.2). Average Max 20.2C (LTA 20.7). Highest 22.4C on 27th. Average Min 13.2C (LTA 13.7).

Weather Summary July 2017

The first ten days of July, whilst not completely settled, were often warm and sunny under the influence of weak ridges of higher pressure. In fact, the hottest day of the month was on the 6th when temperatures at the coast reached 27 Celsius (80 degrees Fahrenheit) and inland values reached over 30 degrees Celsius. After this hot day a thundery trough from France brought some showers, most of which missed the Teignmouth and Dawlish area. The largely fine and warm weather continued until Low Pressure moved across Southwest England on the 11th. The Low Pressure brought spells of heavy rain and cooler temperatures for a day or two before High Pressure once again brought the return of mostly dry and fairly warm weather.

Another area of Low Pressure brought periods of heavy rain between the 18th and 22nd. The night of the 18th/19th was notable for widespread thunderstorms which produced an inch or more of rain in an hour. Although there were some dry and warm interludes during the remainder of the month, rain or showers became more frequent, and lower pressure dominated the weather patterns from the start of the School holidays onwards.

In terms of the statistics for July, the temperature averaged out a little above normal at 18 Celsius and there were at least 18 days when the afternoon temperatures got over 21 Celsius (70 Fahrenheit). Recorded sunshine was 198 hours, that’s 26 hours less than the July average, implying cloudier skies. Rainfall was around 90mm which is double the average and there were up to five days with recorded rainfall of 10mm or more. Despite this there were between 17 and 20 days across the district when no rain was recorded. This is the typical number of dry days for July and leads to the conclusion that July was not as wet as the rainfall total might imply.

In summary, July was warmer, slightly cloudier and had higher rainfall totals than normal, despite an average number of dry days.

Teignmouth Den.  Mean temperature 17.7C (LTA 17.3). Average Max 21.4C (LTA 20.8). Highest 26.8C on 6th. Average Min 13.9 (LTA 13.7).

Total rain 94mm (LTA 45.5). 17 dry days 10 days with 1mm or more. Total sun 198.2 hours (LTA 225).

Dawlish inland. Average temp 17.8C. Highest 30.2C on 6th. Total rain 95.5mm. 19 dry days 10 days with 1mm or more.

Holcombe. Average temp 17.7C. Highest 26.6C on 6th. Total rain 78.5mm. 17 dry days 10 days with 1mm or more.

Teignmouth inland. Average temperature 18.6C. Highest 27.8C on 6th. Total rain 100.8mm. 18 dry days 11 days with 1mm or more.

Weather Summary June 2017

The month started with a series of weather fronts crossing the district. On the 5th a low pressure centre moved across SW England into Wales bringing wet and windy weather. High pressure settled in just before mid month and lasted until the 26th after which a series of low pressure centres moved across southern England. Each of the low pressure centres was associated with periods of heavy and even thundery rain. The High was unusual in that they often develop with cool air across the country. This time warm air fed into the High producing some hot temperatures. Comparisons where made with 1976 but this hot spell was not as widespread or as long lasting as that in 1976.

In fact June will go down in the records as being warmer and wetter than usual which perhaps does not quite tell the whole storey. Yes, there were slightly more wet days than the average but there were  at least eighteen dry days, including two weeks in a row – that’s almost as good as it gets.

It seems to have been a feature of the weather recently that we get a lot of rain in relatively short periods. Last month there were two notable wet periods. The first occurred on the 5th of the month when around an inch of rain fell and the second on the 28th when two inches of rain fell.

The rainfall total for the month ranged from around 70mm in Exminster to around 100mm in parts of the Teignmouth and Dawlish area. The highest total was at Ashcombe where 117mm, or four point six inches of rain, was recorded. Many places had over twice the normal rainfall for June most of which fell during just two days.

During the dry spell temperatures were unusually high with between 12 and 18 days when the afternoon temperature rose over 20 Celsius. For some inland areas afternoon temperatures over 25 Celsius were recorded on 5 days. The hottest day was on the 20th when Teignmouth reached 27 Celsius and many places away from the coast recorded values close to 30 Celsius, which is the mid-eighties in Fahrenheit. For the month as a whole the average temperature was a degree or so above normal.

In summary June was warmer and wetter than average, despite a long dry spell.

Teignmouth Den.  Mean temperature 15.9C (LTA 15.2). Average max 19.6C (18.7). Highest 27.4 20th. Average Min 12.2C (11.6).

Total rain 107.2mm (50.5). Total sun 205.6* hours (222.4).

Weather Summary May 2017

Low pressure over Southwest England brought a very wet start to the month, although the heavy rain had cleared by 10am on the 1st. High pressure followed and brought a week or so of dry weather accompanied by chilly east winds and often rather cloudy skies. After the 11th, Low pressure again took control, leading to several wet days and some welcome rainfall. Between 10 and 15mm of rain was recorded on the 17th and 19th when humid air brought thundery rain from Biscay and into the south of England. From the 21st through to the end of the month, there was another prolonged dry spell, which was also associated with warmer temperatures. Later in the month there was a risk of some heavy thundery rain during the 28th and 29th which affected other parts of southern England, but largely missed the Teignmouth and Dawlish area although there were reports of distant lightning.   

For most places the highest rainfall total for the month was on the 1st when 15 to 24mm of rain fell between midnight and 10am. Teignmouth and Bishopsteignton however recorded over 15mm on the 19th. In most places rainfall in May was near or above normal with totals ranging from around 55mm in the Teignmouth and Bishopsteignton area to around 70mm elsewhere. Teignmouth Den, however, records rainfall from 9am to 9am the next day rather than midnight to midnight. Consequently the heavy rain early on the 1st of May was recorded in the April total which means that the May total of 45.9mm was below the longer term average for Teignmouth Den site.

Teignmouth measured around 187 hours of sunshine in May which is below the long term average of 217 hours and is similar to reports in other parts of the Southwest. Despite reduced sunshine the month was fairly mild and the average temperature was between 13 and 15 Celsius which is one or two degrees warmer than the 30 year average. The warmest days were in the last week of the month when afternoon temperatures typically rose into the twenties Celsius each day and the top temperature was around 23 Celsius. Most places were frost free but inland temperatures dropped to a chilly 1 or 2 Celsius on the morning of the 10th and the Haccombe area dipped to zero Celsius.

In summary, May was warmer but cloudier than normal, with nine wet days and nineteen dry ones.

Weather Summary April 2017

Low pressure brought some rain in the first few days of the month but then High pressure took control. Winds turned southerly around the High bringing warmer air from the continent which helped produce the warmest day of the month on the 9th. A few weak weather fronts moved across the region bringing slightly cooler air until later on the 24th when a cold front brought what was described as “Arctic” air across the UK. Certainly it felt quite cold in the northerly winds and as winds fell light many places had their coldest morning of the month with an air frost on the morning of the 27th. Low pressure replaced the High at the end of the month leading to a very wet spell which started during the morning of Sunday the 30th and lasted through to the morning of Bank Holiday Monday, the 1st of May. Many places had almost an inch of rain on each of the two days.
Looking at the rainfall details across the region it is notable that there were only two or three wet days in the whole of the month with at least 25 days with no measurable rain. More typically one might expect around 10 wet days in April. Rainfall totals around the district where around 30 to 40mm which compares with the long term average of almost 60mm.
Most weather reports used in this summary record data for each 24 hour day between midnight and midnight but some official weather sites record from 9am to 9am the next day. Consequently, for Teignmouth Den this would include rain between midnight and 9am on the 1st of May. The rainfall total at the Den was 52mm around 20mm of which fell in May rather than in April, which just shows what a difference a day can make!
There were around 188 hours of sunshine making April slightly sunnier than average. The month was fairly mild and the average temperature was around eleven Celsius compared to the 30 year average of nine and a half degrees. The warmest day was on the 9th when temperatures reached between nineteen and twenty two Celsius and the coldest morning was the 27th when the temperature lows ranged from 1 Celsius around the coast, to just below freezing inland but down as low as minus two point six Celsius in the Netherton and Haccombe area. Teignmouth escaped an air frost this April which is not unusual as air frosts only occur roughly once every three years. The Netherton and Haccombe area on the other hand recorded five air frosts during April.
In summary, April was much drier, milder and slightly sunnier than normal.

Weather Summary March 2017

The first week of March was rather changeable as low pressure dominated the weather, bringing some rather wet and windy conditions. Indeed, low pressure with relatively mild West or Southwest winds became the main theme of the weather last month. High pressure made some appearances, bringing a few dry days in the second week of the month and almost a week of dry weather starting on the 13th.
Broadly there were around twelve days with no measurable rain but sixteen “wet” days which is rather more than the eleven wet days that might be expected in an average March. The wettest day was on the 3rd with between 15 and 20mm of rain recorded across the area. The rainfall total for March was in the 60 to 80mm range, which is just a little above the long term average.
Despite a fairly wet month the reservoir levels across the Southwest of England remain below normal following the drier than normal winter.
Temperatures were again above normal averaging out near 10 Celsius, almost two degrees above the long term average for the area. For most places the warmest day was on the 9th with a top value of 18 Celsius, although some inland areas had a similar value on the 25th. The lowest value was recorded on the 23rd with temperatures mostly just above freezing. Although most areas escaped an air frost the Netherton and Haccombe area recorded two nights with an air frost and a low of almost minus 1 Celsius.
Given that the month was a little wetter than normal it does not come as a surprise that the sunshine record for Teignmouth shows it was cloudier than average with around 25% less sunshine than a typical March.

In summary, March was cloudier, milder and slightly wetter than normal.

Weather Summary Winter DEC 2016 to FEB 2017

For December to February, nominally the winter months, the mean temperature was at least half a degree above average and rainfall was well below average. Notably, Dartmoor had less than half of the rain that might be expected during winter and this is reflected in the lower than normal water storage in reservoirs across the Southwest.

Weather Summary February 2017

February started wet and windy with low pressure as Atlantic weather systems swept across the country. Temperatures were fairly mild but brief respites between weather systems allowed for a few chilly nights as winds fell light. High pressure over Scandinavia extended across the United Kingdom bringing a week of rather chilly East winds. Despite a number of dry days there was even a flurry of snow on the 11th. By the 13th the southeast wind became quite strong as low pressure tried to muscle in from the west. This caused some problems for the railway as waves crashed over the line and a pebble broke the windscreen of a train. Around mid-month, westerly winds returned and although there were a few days of rain this was followed by another short dry spell. Falling pressure dominated the latter part of the month with further spells of wind and rain, although storm Doris which crossed the UK on the 23rd, did not have much impact on this area.
Looking at the weather statistics for February the average temperature was around 7.5 Celsius which is at least one degree above the long term average for Teignmouth. The warmest day was on the 20th with most places recording 16 or 17 Celsius. The coldest nights were on the 10th or 11th when the temperature in coastal areas remained just above freezing but fell to as low as minus 2 Celsius in Kingsteignton and Haccombe. The average number of air frosts for Teignmouth is 4 but many coastal areas, including Teignmouth, did not record any air frost in February. Inland, however, there were around 5 nights with an air frost, and in Haccombe as many as 9. Our area was not quite as mild as Central England where February temperatures averaged more than two degrees above normal and the 20th was the warmest February day in the Central England Temperature Series since at least 1878.
Rainfall for the Teignmouth and Shaldon areas was around 45mm, or two thirds of the normal February rainfall. Other areas, including Dawlish, recorded up to 70mm which was only a little below average. The wettest days were on the 2nd and 3rd with a 24 hour total of 12mm and there were around 12 “wet” days compared to 14 dry ones.
Sunshine total was 75 hours, which is 10 percent less than average, implying cloudier skies than might be expected in February.

LTA=long term average 1981 to 2010
Teignmouth Den* Total rain 43.7 (LTA 71.8). Days with 1mm or more = 10 (LTA 10.4) Dry days = 15.

2 March2017

Weather Summary January 2017

January started with rain as a cold weather front moved south over the district to be followed by chilly northerly winds and rising pressure. Day time sunshine was followed by cold nights with many places having frosty mornings. For most of us the coldest morning was on the 3rd with temperatures widely around minus 2 Celsius and as low as minus 6 Celsius in some colder inland parts. The chilly weather did not last as winds turned south, then southwest, bringing milder temperatures and just a little rain. From the 10th, Northwest winds brought colder air and lower temperatures accompanied by some showers.
On the 12th, a developing area of low pressure moved east through the English Channel bringing the wettest day of the month with around 20mm of rain. As the low pulled away eastwards cold air from the north turned the rain to snow up over the hills, giving Dartmoor a white covering for a day or two.
High pressure followed bringing a good deal of dry weather and some rather chilly nights. Many places had frosts between the 18th and 25th before milder southwest winds brought a return to cloudy wet weather for the latter part of the month.
Records show that the average temperature was around 6 Celsius which is just a fraction cooler than the long term average for January. For most places the highest temperature of 13 or 14 Celsius occurred on the 3rd of the month although Teignmouth managed 15 Celsius on the 29th. Air frost occurred on as few as 3 nights in some coastal areas whereas inland there was between 9 and 13.
Due to high pressure being fairly dominant during the month, rainfall was below average with around 70mm of rain compared to the more typical value of closer to 100mm. Although there was around 10 wet days, which is less than a typical January, most places had between 15 and 20 days with no measurable rain.
The total number of sunshine hours was close to the long term average of 65 hours which made a nice change from earlier more cloudy months.

In summary, January followed December with below average rainfall and although the temperature was only slightly below average there were more frosts than one might typically expect.

2 Feb 2017

Mid month summary January 2017

Pressure was above average during this period with High Pressure dominant for the first 8 days. Although initially cold cloudy types fed into the high pressure. Lower pressure followed with colder NW to N winds culminating in a potential snow situation as a developing wave depression moved east over the S of UK/English Channel. Heavy rain turned to snow over the hills and especially over the moors on the 12/13 with wintry showers following. Colder air was edged out during the 15th with a return to milder types by the end of the day.
Temperatures averaged out near the 1981 to 2010 mean.
Air frost occurred on 2 or 3 mornings compared to month average of 4.
Rainfall and Sunshine were a little below average.

Teignmouth (1-15th): Den site (some estimated data)
Average temperature 6.6 Celsius. (Max 13.5 Min -1.8). Rain 30mm. Sunshine 23 hours
