After the hottest day of the year at the end of July, August began very warm and sunny and although there was a sharp drop in temperature to a comfortable 24.8°C it continued in the mid-twenties until 6th. Then on 7th the temperature rose once more, reaching 34.5°C on 12th, which was to be the hottest day of the month, not quite as high as July's maximum. Although the highest temperatures were reached in full sun there was quite a lot of cloud in between.

Rain fell on most days for the next week, but only on 18th was the rain heavy, when18.4mm was recorded, again with thunder. The barometer had been falling steadily since 8th to reach its lowest point in the month.

The rest of August was cooler, ranging from 23.2°C on 20th down to 16.7°C on 29th but with plenty of sunny periods. Only the last five days did not reach 20°C.

Significant rain from slow-moving fronts fell on 24th/25th with 14.9mm, 27th with 14.6mm and 28th with 10.2mm. Total rainfall was 101.9mm, 181.6% of average and the wettest August since 2010. Only February was wetter this year. It brought the total for the summer to 206.6mm, 135% of average. The year's total was 483.7mm, 114.8% of average.

Night time temperatures ranged from a maximum of 19.9°°C after the hottest day down to 10.7°°C on 31st.

The wind was mostly light, from all quarters, but became fresh to strong south westerly on 21st, 22nd and 25th.

August was sunny and hot until the hottest day on 12th when the weather broke and was wet for the next week, becoming more unsettled but with plenty of sun for the rest of the month.
