The averaging period used for the following assessment was 1981-2010.
At the start of July the weather was breezy and showery, with low pressure in charge. Unsettled conditions persisted for much of the first half of the month, with fronts frequently bringing rain to the north and west, although rainfall amounts were generally small in the south. It was generally warmer and sunnier between the 17th and 23rd, with a brief hot spell from the 18th to 20th, which triggered a thundery breakdown in the north and across parts of East Anglia. Changeable weather resumed during the last week, with further frequent belts of rain, but again many southern areas often stayed dry.
The UK mean temperature was 15.3 °C, which is 0.2 °C above the 1981-2010 long-term average. Mean minimum temperatures were slightly above average in all regions, but mean maximum temperatures were slightly below average in the west. Rainfall was 101% of average, but with a strong north-south contrast. It was generally wetter than average in Scotland, Northern Ireland, Cumbria and Snowdonia, but drier than average in south Wales and the southern half of England, with less than 5 mm of rain locally in the far south. Sunshine was 91% of average, and it was cloudier than average in Scotland, Northern Ireland, west Wales and parts of western England, but sunshine was slightly above average over much of eastern England.
The UK monthly extremes were as follows: A maximum temperature of 33.5 °C was recorded at Brize Norton (Oxfordshire) on the 19th, with 33.9 °C at Jersey Airport (Channel Islands). A minimum temperature of 0.5 °C was recorded at Altnaharra (Sutherland) on the 2nd. In the 24 hours ending at 0900 GMT on the 21st, 87.2 mm of rain fell at Hungry Snout (Borders). Wind gusts of 49 knots (56 mph) were recorded at Needles Old Battery (Isle of Wight) on the 10th and 11th.
July's weather was mostly benign, with significant weather-related impacts observed only on four days.
On the 11th, showers caused some localised impacts at Farnborough Air Show. Further showers on the 12th caused flooding at the Harrow North and Pinner tube stations and on the railway between Norwich and Great Yarmouth, and a primary school closed in Stevenage due to power loss and flooding.
Hot weather on the 19th caused a few heat-related impacts on railways in the south of England.
A thundery breakdown on the 20th caused widespread disruption away from the south. Lightning caused power impacts in Blackpool, Carlisle, Penrith and Keswick. Lightning also struck houses in Little Hoole (Lancashire), Ysbyty (Gwynedd), Penruddock (Cumbria) and a church steeple was badly damaged in Denny near Falkirk. Lightning also caused issues on railways in north-east England. In Denny, a GP Surgery receptionist was hospitalised after lightning entered the building and struck her chair. Lightning also affected phone lines in Eyemouth in the Scottish Borders. There were many flooding and surface water-related impacts; a school in Cockermouth closed, Edinburgh Zoo closed, and there were other isolated flooding incidents in Cumbria and southern and central Scotland. Large hail (2-3 cm diameter) caused some damage to caravans near Annan in Dumfries and Galloway.
