The averaging period used for the following assessment was 1961-1990.
Average daily maximum temperatures ranged from about 1 °C below average across south-western areas of the UK to about 1 °C above average across some eastern coastal areas of England. Average daily minimum temperatures were generally 1 to 2 °C above average across the UK. It was a very wet month across much of the UK with widespread flooding reported in Northern Ireland and parts of eastern Scotland. Northern Ireland had its wettest August in a series back to 1914. It was also an exceptionally dull month across much of the UK, with only the far north of Scotland recording above average sunshine.
Faversham (Kent) recorded a maximum temperature of 27.5 °C on 6th. Altnaharra (Highland) recorded a minimum temperature of 0.5 °C on 15th. Trassey Slievenaman (County Down) recorded 96.0 mm of rainfall on 16th. A wind gust of 79 mph was recorded at Needles Old Battery (Isle of Wight) on 13th.
Very unsettled with heavy rain or showers for much of the month. It was also an exceptionally dull month.
1st to 6th: It was very unsettled with low pressure covering the UK for the first five days of the month. There were showers or longer spells of rain and some of these were heavy with scattered thunderstorms. Temperatures were generally near or a little below average, but it became locally warm in any sunnier breaks in the east and south-east. On the 6th, low pressure moved to the north-west for a time and allowed some warmer weather to edge into central and south-east England for a time. The temperature reached 27.5 °C at Faversham (Kent) on the 6th. However, later in the day, these higher temperatures helped to spark off a few heavy thunderstorms across the far south-east.
7th to 11th: Low pressure to the north-west brought generally south-westerly winds, with rain or showers at times, some heavy and thundery. Heavy thunderstorms on the 7th gave some torrential rain across East Anglia, with Marham (Norfolk) recording 15.2 mm in the hour ending 22:00 UTC, and reports of a tornado at Lakenheath.
12th to 14th: With low pressure over the UK, England had some very unsettled days with showers or longer spells of rain. It was windy too with gusts to 50 or 60 m.p.h. in some exposed southern areas. Temperatures were generally below average.
15th to 16th: Higher pressure brought much drier conditions, especially to eastern England where there was some pleasant sunshine. However, by the end of the 16th, heavy rain was spreading back into the west.
17th to 23rd: Low pressure returned, with very unsettled and at times windy conditions. There were rain or showers, and many of the showers were heavy with thunder, especially for northern and eastern England. Showers became less frequent from the west on the 22nd. A ridge of high pressure brought drier and sunnier conditions on the 23rd after a very chilly night for August. Temperatures fell to 4.8 °C at Fontmell Magna (Dorset), but rose to near average values in most places in sunshine during the day. Cloud and rain spread to many western areas later.
24th to 25th: Low pressure near Iceland with westerly winds. Weather fronts moving east brought outbreaks of rain, but these were generally lighter than on recent days and eventually brought in warmer and more humid conditions.
26th to 31st: High pressure to the south brought mostly dry conditions. However, with high humidity and westerly winds, it was generally very cloudy or dull with disappointing daytime temperatures and very mild nights. Some cloud breaks did develop in the south on the 30th and it became locally warm by day, with Kew Gardens (London) recording a temperature of 26.9 °C. A return to unsettled conditions on the 31st, but not before sunshine brought a hot day to parts of East Anglia with temperatures reaching 26.2 °C at Wattisham (Suffolk). However, thundery rain spread north-eastwards with some torrential downpours across parts of London and Norfolk during the afternoon and evening, with Hampstead (London) recording 35.2 mm. It turned cooler from the west in the rain.
Very unsettled with heavy rain or showers for much of the month. It was also an exceptionally dull month.
1st to 6th: Rather unsettled through the first few days with scattered showers or longer periods of rain, although these were interspersed with some brighter periods. The 4th was largely dry and sunny with a weak ridge of high pressure building. The wet weather returned on the 5th and 6th with some heavy rain, especially in the south. Temperatures generally near average, although Colwyn Bay (Conwy) recorded a temperature of 23.2 °C on the 6th.

The 18th was a wet day, with heavy rain at times, and strong south-westerly winds. The 19th, 20th and 21st continued unsettled with rain or showers, and some brighter spells.
