HEADLINE: A TYPICAL EARLY AUTUMN MONTH THIS YEAR

September 2018 in many ways was a typical early Autumn month with hints of summer warmth hanging on but definite hints of the fast approaching Winter season too with several frosts through the month. Unusually in September there was a couple of air frosts here in the valley with -0.8C 30F in the dawn of the 25th being the lowest September minima for 15yrs. Conversely there was still some pleasantly warm days aplenty with 24.0C the highest temperature in the afternoon of the 3rd. Overall the chilly nights outweighed the warm days meaning an average temperature ending below average by 0.8C at 13.5C.
Rainfall was pretty average overall though this doesn't tell the whole story because 30mm of this total fell on the 21st-22nd (9:00-09:00) with 19 days seeing no measurable rain at all so all in all it was dry a lot more time than it was wet this September.
There were no notable winds over our area though the 21st saw gusts of 40mph across the area in association with the wettest period of the month too The predominate direction of the wind through the month was a point just north of West at 47% of the time.
Sunshine through September was pretty average overall with 123hrs or so shining across the village through the month. There were two joint sunniest days, each clocking up 10.8hrs on the 26th and 29th while just two days saw no sun at all namely the 20th & 22nd. The brightest ambience was on the 7th while the dullest day was the 22nd again associated with the thick cloud and heavy rain that day. UV Levels were naturally ebbing away through the month as the sky lowers down the sky with a UV Level of 4.4 being the highest monthly level on the 10th.
There was no thunder or hail reported through the month and no other unusual weather phenomemna to report on either.
So overall September 2018 will go down as a benign month for weather with temperatures a little below average while sunshine, wind and rainfall all fell into the average category.

REPORT

Summer 2018 will go down as a very warm one. For us locally the average temperature ended up 1.5C above the long term mean which achieved 17.7C which for me was the warmest Summer since my modern records began back in 2000. It ended up much drier than average with just 158mm of rain compared to a long term average for the three summer months of 238mm. It was also a very sunny summer with a total of 586hrs comparing with the average of 460hrs as a long term mean. So a Summer that was comparable to the great summer of 1976 being much sunnier, drier and warmer than average.
JUNE 2018 will go down as being a much warmer than average month with some hot spells but more notably long dry spells
Starting with temperature and the warmer than average month was helped by the hot spells in the last third of the month peaking with a temperature of 30.1C on the 26th but there were other days not far behind. Nights were cooler than could of been thanks to the very dry air across the area with a record low humidity of just 19% on the 26th. The lowest temperature occurred on the morning of the 22nd at just 4.6C which is quite low for a near longest day. The average temperature for the month was 1.7C above the long term average at 17.0C
So what about rainfall. Well June this year was much drier than average with just 21mm of rain falling through the month and half of that falling in the opening days. A very drizzly spell around mid month accounted for the rest but totals were some 40mm or so over my long term average for the area.
Winds were mostly quite light with the highest gust of 27mph occurring on the 14th & 16th
Sunshine amounts were well above average with a staggering 4 successive days when the maximum sunshine in our area could be recorded was attained at 15.2hrs on the days between the 24th-27th. The totl sunshine for the monh was 224.2hrs with just two days when there was no sunshine on the 7th and 17th. UV Levels were high at times and 7 was the highest reading obtained at lunchtime on the 20th. The brightest day was the 26th when 345.1w/sqm was averaged across the daytime while the dullest day was on the 8th when 103.9w/sqm was achieved.
There was no thunder, lightning or hailstorms to report this month neither was there any fog or acourse snow and frost.
So a much warmer and drier than average June 2018 was the result of a large High pressure which at time of print looks like extending well into July too.
July 2018 will go down as a continuation of the overall very dry and very warm theme and occasionally hot. There was 23 days in the month which the temperature exceeded 25C over the area and the remainder not far under. It meant the highest temperature for the month was on the 26th when 31.4C 89F was reached with several others in the 30C range. The mean temperature was 2.8C above long term mean at 19.6C 67F. There was no cold nights with the minimum temperature for the month at 9.0C on the 19th.
Rainfall too was well below average with just 44mm (1.76inc) falling through the month with 25.0mm on 1 day on the 28th as the weather broke down. The end of the month did make up for what would of been a record breaking dry month had it not been for the 40mm that fell over the last few days of the month.
Sunshine was well above average too with 15hrs and 12mins of unbroken sunshine on the 6th and 230hrs or so for the month as a whole. There were no sunless days with the least sunny day at just 12mins on the 29th.
Despite the heat there were no notable thunderstorms with just local claps in the storms at the end of the month but there was a weak funnel cloud seen in a showery zone of weather on the evening of the 30th to the NW.
So July will be renowned for the incredible lengthy dry period when coupled with June and probably into August too. It was also hotter and sunnier than average by some margin.

August 2018 will in many ways go down as an unremarkable weather month as the weather was often benign and driven by High pressure not far away to the SW and South. As always though the detail will always be of interest and while there was no exceptional weather events of any kind the month still ended up on the warmer side of average.
Temperatures peaked at 29.1C on the 5th but there were many more days especially early in the month which exceeded 25C. The lowest temperature was just 4.6C on the 31st, an indicator that Autumn was on its way. The 0.3C above the long term average mean meant the months average temperature was 16.6C.
Rainfall should of been below average given it only rained on 12 days of the month but the figure was inflated by a particularly wet day on the 26th when just under 25mm fell. The months total was 93.3mm which was just 6mm above the long term mean.
Sunshine was again in plentiful supply with 131hrs and 24 mins the total amount with the sunniest day being the 5th when 12hrs and 42mins was the highest daily total. This was a bit above the long term mean for the month.
There was no notable wind with 22mph the top gust on the 10th & 24th with the months predominent direction being between West and North.
There was no thunder, lightning, hail or other phenomemnon through the month which made it as indicated at the start a very sedate end to a beautiful summer

REPORT
January 2018 was a very wet Winter month and somewhat milder than average too.
Temperatures were 0.6C above the long term average for the area with the highest temperature of the month on the 23rd at 13.2C. The coldest night was a frosty -3.4C on the night of the 30th though this is hardly a record breaking cold night for a mid Winter month. There were just 36hours in the month that saw temperatures below freezing.
Moving on to rainfall and this was by far the biggest feature of the month. Following on from Decembers wetter than average month January is the second consecutive month to carry on that trend with 153mm of rain through the month. On my own records this is some 43mm above the average of my own records for a January month. The wettest day was the 21st when 23mm of rain fell. There was no snowfall to add to this total though some snow flurries did occur on the evening of the 16th.
Winds were fresh to strong at times with some gales but the strongest gust was 47mph on the 24th-all standard stuff for a mid Winter month.
Sunshine was below average too with just 59hrs over the month with the sunniest day on the 10th with 6.3hrs
There was no thunder and lightning this month but there were several occasions when hail fell, namely the 16th, 18th and 19th.
So all in all nothing too dramatic this month with yet again no substantial settling snow over the area mostly due to the almost entire Atlantic dominated weather patterns which adorned nearly all of the month.
February 2018 will be remembered by two factors which dominated the month. Firstly it was a very sunny month and secondly it turned exceptionally cold in the last few days.
Taking the parameters in sequence temperatures were below average by some considerable margin mostly due to the bitter cold end to the month though there was rather colder conditions than average early in the month too. There were a few exceptions with the highest temperature of 11.9C reached on the 19th in a short milder interlude but the lowest temperature of -6.9C was a very bitter evening on the 27th. The average temperature of 3.0C was 2.2C below my long term mean mostly due to a lot of mild February's in the recent past.
Rainfall was a little below average though there were some wet days, the wettest being the 14th when 19.0mm fell. There were a lot of dry days though and these amounted to 20/28 so it certainly wasn't a wet month.
Wind strength was nothing more than average with the highest gust recorded on the 13th when 45mph was achieved
Sunshine amounts though were miles above the average for February thanks to the cold, crisp, sunny conditions accompanying the cold weather at the end of the month. The sunniest day was the 25th when the maximum of 9hrs and 48minutes was recorded. The monthly total was a massive 172hrs and 30 minutes-the sunniest February I have ever recorded.
It was a very frosty month and there were air frosts recorded over 17/28 nights.
The occurrence of snowfall was up on recent years though no settling snow was recorded other than a dusting on the 28th. Snow was recorded falling on 5 days in the month.
There was no fog, freezing or otherwise to report in February, nor was there any thunder and lightning episodes. Hail featured from showery days on the 12th and 15th.
So in a nutshell February 2018 can be summed up as colder, drier and sunnier than average.
March 2018 although a Spring month was far from it this year with the significant factors of the month being much colder, very wet and dull. The month started bitterly cold as the dying embers of the very cold spell at the end of February spilled over into March. The lowest temperatures of the month were recorded on the 1st with -5.4C recorded soon after midnight. It was followed by 2 Ice days where temperatures failed to exceed freezing point even by day on both the 1st and 2nd aided by the snow that was lying across the ground at the beginning of March. Things did warm up though soon after with a thaw but temperatures remained suppressed for much of the month really with another cold, snowy period between the 17th-20th of the month with temperatures only just making positive territory very briefly on the 18th. In some of the warmest moments of the month temperatures did make respectability with 13.6C on the 26th which ended up the highest month temperatures occurring just ahead of another cold period to end the month. So with all this talk of cold the average monthly temperatures was -1.9C below the long term mean Actual frost hours for the month were well above average at 118.9hrs.
Moving on to rainfall and you could basically say that through March if it wasn't snowing it was raining as it really was a very wet month. A total of 167mm (6.68inc) of rain fall through the month with the 9th, 11th, 14th, 28th and 30th all very wet days. The wettest day was the 30th with 18.2mm falling in the 24 hour period 9am-9am. Coupled with the rain we had the snow melt water exacerbating the wet sodden ground.
Amounts of sunshine were very limited and it was the dullest March of the millenium with just a pawltry 69.9hrs of sunshine-8.5hrs of that shining on the 26th making it that the sunniest day of the month. The dullest day of the month was the 18th following heavy snowfall but there were many gloomy days at various points through the month.
Winds were less of a feature overall but they did contribute to problems with drifting snow both at the beginning and middle of the month. The strongest gust was 40mph on the hills above the valley on the 14th.
Snowfall occurred with much more frequency than usual with a total of 33cm of lying snow settling over the month though a thaw rapidly followed each snowfall so settled snow was just a temporary problem.
There were no other unusual phenomenon through the month apart from small hail from showers on the 16th & 29th on what was a cold, wet and dull month overall.
April 2018 was a milder than average month at 0.8C above the long term mean. Despite this there was some relatively cool weather and a markedly chilly spell right at the end of the month. The month's average of 10.1C was skewed slightly by the very warm if short period around the 18th & 19th. 24.4C was recorded on the 19th which was the highest month temperature. We were spared any air frost this month which is quite unusual and the lowest temperature I recorded through April was on the 1st at 1.9C.
Rainfall was about 20% above the average for April clocking in at 97mm for the month, the wettest day being the 1st when 23mm fell in the 24hr period. There were some dry days of course, 13 of them in fact but at no point through April were there anymore than 3 consecutive dry days.
Winds were'nt much of an issue through the month but there was some windy days. The strongest gusts here in the village was just 23mph on the 18th while on the hills above the village 35mph was reached on the 6th.
Sunshine amounts were 25% down on the average with just 103.8hrs the total for the month. The sunniest day was the 19th during the very warm period when 13hrs and 12minutes shone down on the village. As a reflection of how cloudy a month it was though there were 8 days out of the 30 which saw no sun at all with 5 consecutive days of this between the 8th-12th inclusive.
By far the most spectacular event of the month was the thunderstorm which crossed the area on the evening of the 21st. After a fine and warm day the skies dramatically turned dark in the early evening almost instantly with a torrential thunderstorm with hail, a rain rate of 220mm/hr briefly and many lightning strikes close by over the village crossing SW to NE across us. The lightning continued to be visible on over into the early hours of the 22nd as the storm system affected other parts of the South of England too.
We were spared any fog, frost or snow through the month and any other unusual weather phenomenon for that matter though I should note that at the time of writing this report we have had an air frost on the morning of the 1st of May.
So summing up April was milder, wetter and more cloudy than average with less in the way of the usual Spring mixture of hail, sleet, snow and frost than is normal for this Spring month.

MAY 2018 was a drier and warmer month than average this year. There were some sharp contrasts in temperature with the beginning of the month really chilly by night with an unusual for May air frost on the morning of the 1st when -0.9C was the lowest month temperature.
Soon after the month began things turned around with a hot spell developing towards the end of the first week when 28.3C was the highest temperature reached on the afternoon of the 7th. The average temperature was 13.4C which is just over 1C above the long term mean.
Rainfall was below average and clocked in at just 70% of the 90mm average for the month with 55.5mm the month total. As always some wet days made up a lot of this total with 16mm falling on the 1st and 14mm on the 24th. These were the only two major rain events of the month. Towards the end of the month the weather turned thundery with a severe thunderstorm briefly on the evening of the 27th and a lesser storm on the morning of the 28th.
Winds were very low through the month and with winds predominating from an easterly quarter with very little Atlantic influence they were not a feature at all with the strongest gust just 30mph on the 2nd the highest recorded.
Sunshine amounts were very impressive clocking up 220hrs for the month some 60hrs above the long term mean. The sunniest day with 14.5hrs on the 19th which gave us one of those rare days when no cloud was visible with maximum sunshine possible from dawn to dusk.
​So that's it for May and Spring 2018 which ended in a pleasant enough month which seemed like compensation for the couple of bitterly cold spells earlier in the season

JUNE 2018 will go down as being a much warmer than average month with some hot spells but more notably long dry spells
Starting with temperature and the warmer than average month was helped by the hot spells in the last third of the month peaking with a temperature of 30.1C on the 26th but there were other days not far behind.

There was no thunder, lightning or hailstorms to report this month neither was there any fog or acourse snow and frost.
So a much warmer and drier than average June 2018 was the result of a large High pressure which at time of print looks like extending well into July too.
July 2018 will go down as a continuation of the overall very dry and very warm theme and occasionally hot. There was 23 days in the month which the temperature exceeded 25C over the area and the remainder not far under. It meant the highest temperature for the month was on the 26th when 31.4C 89F was reached with several others in the 30C range. The mean temperature was 2.8C above long term mean at 19.6C 67F. There was no cold nights with the minimum temperature for the month at 9.0C on the 19th.

There was no thunder, lightning, hail or other phenomemnon through the month which made it as indicated at the start a very sedate end to a beautiful summer.
