The averaging period used for the following assessment was 1981-2010.
At the start of August the weather was unsettled with low pressure in charge, and wet in the south. It was generally changeable during the first fortnight, and windy at times in the first week. It was often more settled in the second half, although the 20th had a notably vigorous depression for the time of year which brought strong winds to many parts of England. Frequent southerly winds brought a spell of high temperatures over much of England, especially East Anglia and the south-east, which peaked on the 24th when a few spots reached close to 34 °C.
The UK mean temperature was 15.5 °C, which is 0.6 °C above the 1981-2010 long-term average. Mean maximum temperatures were 1.5 to 2 °C above average in East Anglia, but closer to normal in most western areas. Mean minimum temperatures were generally slightly above normal except in northern Scotland, where a few sites fell to -1 °C on the 10th. Rainfall was 96% of average, and it was a wet month in parts of northern England and the Hebrides, but dry in East Anglia, south-east England and Northern Ireland. Sunshine was mostly rather above average except in Northern Ireland, and the UK had 111% of the long-term average overall.
The UK monthly extremes were as follows: A maximum temperature of 34.1 °C was recorded at Faversham (Kent) on the 24th. A minimum temperature of -1.5 °C was recorded at Kindrogan (Perthshire) on the 10th. In the 24 hours ending at 0900 GMT on the 21st, 81.0 mm of rain fell at Seathwaite (Cumbria). A wind gust of 60 knots (69 mph) was recorded at Needles Old Battery (Isle of Wight) on the 20th.
On the 3rd, a landslip caused the closure of a main road and rail route in Sutherland, leading to a temporary, but significant diversion for local traffic, and the cancellation of rail services. Unseasonably strong winds on the 7th led to the cancellation of numerous outdoor events across Scotland, and affected train services and power supplies and power outages. Fallen trees affected rail links between Dundee-Aberdeen, Glasgow-Oban and Inverness-Wick, and there were restrictions on Scotland's bridges. A 17,000 tonne oil rig ran aground at Carloway on Lewis after breaking its towing line in high winds and seas.
On the 11th and 12th, as a result of persistent heavy rain, a campsite was flooded and there was localised road flooding on Mull. The Crinan Canal was closed for safety reasons, and a landslide affected road and rail links between Fort William and Mallaig.
Unseasonably strong winds on the 19th and 20th led to disruption especially over south Wales, south-west England and the south coast. Fallen trees were reported to have caused localised travel disruption on roads across south and west Wales, the Midlands, Derbyshire, Nottinghamshire, Hull, Cambridgeshire, Sussex and Hampshire. In addition, a number of events, such as the Northwest Wales Music Festival, and the Northants Balloon Festival were cancelled. High seas led to the deaths of three men, two women and a young boy in incidents around Britain's coasts on that weekend in Cornwall, Dorset, Essex, Jersey and Aberdeen.
On the 22nd, a number of localised flooding impacts from heavy rain were reported across Cumbria and Lancashire trains between Preston and Lancaster were cancelled after the line was flooded, a multi-agency group formed to manage some small scale property evacuations and road closures in Bootle, Cumbria, and localised road and rail flooding was reported across other parts of Cumbria.
On the 26th, localised flooding caused traffic disruption on the A6 in Leicestershire, pockets of property flooding in west Norfolk, the village of Kirton, Lincolnshire was cut off for a time, property flooding was reported in parts of Dorset and Wiltshire, and lightning strikes were reported to have caused a Tesco roof to collapse in Boston.
On the 28th, a Medieval Festival at Beaumaris Castle in north Wales was cancelled after the site flooded, heavy rain flooded a car park at the Blyth Tall Ships Regatta, and localised travel disruption was reported across parts of Redcar and Cleveland due to flooding.
