August 2016 Weather

It was a warm, sunny and largely dry August this year with average temperatures just over one degree centigrade above the 1981-2010 average for central East Yorkshire. Indeed the average temperature of 17.4 C makes this the joint warmest August on my records dating back to 2003, whilst the highest temperature recorded was a rather hot 27.7 C, just 1 C below the highest ever August maximum recorded here.

Rainfall wise the month was predominantly dry, in fact up to the 19th the monthly rainfall total was a mere 3.8 mm (0.15 inches), whilst just six days saw rainfall in excess of 1 mm during the course of the entire month. However during the period from the 19th to the 27th some 44.8 mm (1.76 inches) of rain was recorded at the weather station, including 21.4 mm (0.84 inches) on the 25th alone, this short-lived wet spell preventing what would have otherwise been an exceptionally dry month. Thunder, a phenomena which has been rare this year, was recorded on just one day, a band of heavy and thundery rain on the 27th producing a few rumbles as it passed through the East Riding.

Sunshine meanwhile was in plentiful supply throughout most of the month with a respectable average of 6.64 hours being recorded daily, whilst 113% of the long term average was recorded. Only two days saw no sunshine whatsoever. Finally winds were predominantly from the west and south, with westerlies and south-easterlies dominating.

11.7 C to 20.8 C / 0.2 mm / 5.7 hours / W 2
A sunny start to August (and Yorkshire Day!) with plenty of sunshine bathing the Wolds and the East Riding during the morning, but in the afternoon skies would become cloudier. Indeed it would look quite threatening at times but in the end, apart from the odd drop or two, it would remain largely dry. Remaining cloudy throughout the evening, nightfall coming noticeably early thanks to both the overcast skies and the now shortening days, whilst overnight the cloud would become thick enough for some outbreaks of mostly light rain and drizzle towards dawn. Cooler and fresher feeling.

2nd August 2016, Tuesday
13.9 C to 19.0 C / 0.2 mm / 0.0 hours / SE 3
A grey and disappointing day with outbreaks of drizzly rain at times, especially in the morning and again in the evening, the onshore breeze also making it feel quite cool for the time of year. Remaining cloudy for most of the night with temperatures falling no lower than 15.5 C.

3rd August 2016, Wednesday
15.5 C to 23.0 C / 0.0 mm / 5.8 hours / SW 4-5
An initially cloudy start but soon brightening up with sunny spells developing by mid-morning. Remaining bright in the afternoon with alternating sunnier and cloudier periods, though the main feature of the weather was the fresh south-westerly breeze which occasionally buffeted the old family homestead. Variable amounts of cloud in the evening and overnight and remaining breezy.

4th August 2016, Thursday
14.8 C to 22.3 C / 0.0 mm / 5.9 hours / W 4
A cloudy morning for the most part, with even a brief shower around 10 am, but thereafter brightening up with alternating sunnier and cloudier periods. Feeling warm with temperatures around average for the time of year, though like yesterday it was quite breezy at times as well, especially in the morning and early afternoon. Variable amounts of cloud overnight but becoming cloudier later.

5th August 2016, Friday
13.3 C to 21.4 C / trace / 6.3 hours / W 4
A cloudy start with some drizzle for a time around 9 am but as the morning progressed things would steadily brighten.

Clear spells in the evening and overnight with the breeze becoming light during the night.

6th August 2016, Saturday
12.2 C to 24.8 C / 0.0 mm / 12.0 hours / SW 4
A sunny and warm summer’s day with plenty of sunshine bathing the East Yorkshire countryside and temperatures climbing up into the mid-twenties. Indeed hadn’t it been for a cooling south-westerly breeze it would have felt rather hot. Clear spells in the evening and overnight, though despite the clear skies temperatures would fall no lower than 17.2 C, certainly one of the warmest August nights on our weather records!

7th August 2016, Sunday
17.2 C to 23.2 C / 0.3 mm / 11.6 hours / W 5-6
A sunny and warm morning with temperatures already above 20 C at 9 am, though a brisk westerly breeze did help to keep temperatures pegged back as the sun rose ever higher in the early August sky.

13.9 C to 23.5 C / 0.0 mm / 11.3 hours / SW 5
