England diary of highlights

A warm and dry start to the month, but becoming increasingly unsettled. A sustained spell of heavy rain over Lincolnshire, most of Yorkshire and the Midlands on 24-25th, with widespread flooding being reported.

1st to 3rd: This was a transition period, prior to the development of a ridge of high pressure over the British Isles. An Atlantic low brought weakening fronts to the west and north, with some sharp showers in the north on the 1st and more general rain to the north on the 3rd. It was also very warm, with temperatures reaching around 25 °C in the London area on the 2nd. North Sea coasts began to be plagued by low cloud and fog.

4th to 12th: Ridge of high pressure slowly declining with thundery troughs affecting eastern districts. Many places were fine and warm at first, though the east saw relatively little sunshine after the 4th. Cloud became widespread across the country by the 7th and there were some heavy thunderstorms over East Anglia and the south-east on the 8th, with Herstmonceux reporting 33 mm of rain in 6 hours. It was still warm, with temperatures usually reaching 22-24 °C and up to 26.1 °C at Pershore on the 9th. The south-west and the north became showery later. Winds were generally light throughout.

13th to 17th: A deep depression south-west of the British Isles moved slowly north-east across the country, filling slowly. A spell of heavy and thundery rain pushed north across all districts on the 13th, giving 15.6 mm in an hour at Ellesmere Port. Heavy and thundery showers developed each day, giving some very high totals in places, with Edgbaston reporting 70 mm in 12 hours on the 15th. It was very warm and humid at first, with temperatures reaching 25 °C at Gravesend on the 13th, but it became significantly cooler as winds turned more northerly. Central and north-eastern districts saw the highest rainfall.

18th to 23rd: Low pressure dominated the weather, with a slow-moving depression deepening to the south-west of Cornwall before moving north-east across the country as it filled. There were some very heavy showers with some funnel clouds being reported, with 21.4 mm falling in an hour at High Wycombe on the 19th and flooding reported in Boscastle on the 21st.

24th to 30th: An exceptional spell of wet weather, with spells of rain or showers throughout most of the period. A deepening depression became slow-moving over the country on the 25th bringing a sustained spell of heavy rain to Lincolnshire, most of Yorkshire and the Midlands, with widespread flooding being reported. Many places recorded over 50 mm of rain in 12 hours and Fylingdales recorded over 100 mm in the 24-hour period ending 2100 UTC on the 25th. There were also very strong northerly winds in places, with a gust of 56 knots being recorded at Berry Head.

Wales diary of highlights

A warm and mostly dry first half of the month but then cooler and changeable with some heavy rain at times.

1st to 13th: High pressure affected much of the UK with mainly dry, settled and warm conditions across Wales. Temperatures up to 22 °C occurred for several days with a peak of around 26 °C in N Wales on the 11th. It was often sunny as well.

14th to 30th: In complete contrast, the rest of the month was entirely dominated by areas of low pressure giving typically unsettled and changeable weather that was often quite cool as well.

Persistent and heavy rain on the 25th continued the unusually wet weather with up to 75 mm of rain in some parts. Although quieter conditions then affected the country over the next few days with generally lighter and more scattered showers, yet more heavy rain spread in from the west on the 30th.
