Overall an average amount of rainfall, but because recent Julys have tended to be dry, it was the wettest since 1993.

Severe storms, with accompanying heavy downpours, affected North Wales and SW Scotland on the 3rd, and south Wales on the 4th. Flooding in Lanrkshire and outskirts of Glasgow on the 3rd. At Wishaw the storm started at 10.45pm, peaking at 60 flashes of lightning a minute, and giving 69.2 mm of rain in one hour. There was flooding in Cardiff, following 67 mm of rain in less than six hours, although it is likely that more than 125 mm fell in parts of mid-Wales. More severe storms affected the south, SW, and Midlands of England on the 5-7th. Meanwhile 32C (90F) was recorded at St Helier (Jersey) on the 3rd, and Rickmansworth (Herts.) on the 5th. After the first week, the weather became much cooler and more unsettled. Norwich recorded 61 hours of sunshine in the first seven days, and only 20 in the next seven. There were some unusually low minima midmonth, with +0.3C recorded at Sennybridge (Powys) on the morning of the 16th, and 3C widespread across the Midlands.There was more heavy rain 17-19th. After the unsettled spell, a ridge of high pressure brought fine, hot weather to England and Wales, with temperatures peaking around 32C in London on the 28th and 29th. It was the dullest July for 10 years across parts of Scotland, while it was sunnier than average across England and Wales.
