UK climate video
Temperatures for July were above average across the UK, mainly due to warm days with many days having maximum temperatures above 25 °C, especially in the south-east. However, night-time temperatures were closer to average. There was plenty of warm, dry, sunny weather, but with the warmth leading to thunderstorms and localised downpours at times; the heaviest rain was generally across the south-east and East Anglia.
The UK mean temperature was 16.3 °C, which is 1.2 °C above the 1981-2010 long-term average. This ranks as the equal-8th warmest July in a series from 1910, but was not as warm as July 2013. July 2014 was the 8th consecutive month with above average temperatures for the UK. Rainfall was rather below average overall, particularly across Devon, Cornwall and south-west Wales, but well above average in parts of East Anglia. The UK overall received 83% of average rainfall. It was a sunny month for most areas, especially the west and north, with 129% of average sunshine hours for the UK overall, making it the equal-sixth sunniest July in a series since 1929 - though not as sunny as July 2013.
A maximum temperature of 32.3 °C was recorded at Gravesend (Kent) on the 18th. A minimum temperature of 0.8 °C was recorded at Katesbridge (County Down) on the 1st. In the 24 hours ending at 0900 GMT on the 5th, 92.6 mm of rain fell at Ennerdale, Black Sail (Cumbria). A wind gust of 59 mph were recorded at Warcop Range (Cumbria) on the 18th.
Heavy showers caused some localised flooding in parts of England and Wales on the 7th and the 8th, with some notably high rainfall totals. The 10th was a wet and particularly cool day for parts of eastern England.
A warm spell of weather around mid-month ended in thunderstorms and heavy showers for some regions during Friday 18th to Sunday 20th; Norwich Airport recorded 45.8 mm - three-quarters of the normal monthly rainfall amount - in one hour. There was some flooding and disruption reported, with damage due to lightning strikes and problems with railway signalling equipment.
Heavy showers and thunderstorms resulted in some large rainfall totals in south-east England from 27th to 29th. Flash flooding caused localised problems on roads and railways in parts of Sussex on the morning of the 28th.
The Opening Ceremony of the Commonwealth Games in Glasgow on 23rd July and first few days of competition saw plenty of fine, warm, sunny weather. However, unfortunately the warm and often rather humid conditions resulted in ideal conditions for slugs in the UK's gardens, and also for mosquitoes in the London area.
