UK long range weather forecast
The end of August should see a split in the weather across the UK, with dry and sunny conditions prevailing across many areas, in particular southeast England, and for cloudier conditions across the far northwest. The far northwest will see rain at times, followed by periods with sunny spells and showers. Any strong winds will also be restricted to the far northwest. August temperatures will be above average overall and hot in the southeast, but closer to average in the far northwest. There is lower confidence for early September with quite mixed signals, however, it is likely that the most prolonged sunny periods will be in the south and that it will be more changeable in the north. Temperatures only at or slightly above average for the time of year.
Confidence remains rather low during this period, but most areas should see some spells of fine, dry, and sunny weather. These spells of fine weather will be most prolonged in the south of the UK. Northern parts are likely to see more changeable conditions through this period with spells of rain and stronger winds, these extending further south at times too. On the whole temperatures will be closer to or slightly above average for the time of year.
