PrecipitationMostly below average.
1/9 to 7/9
A good deal of settled weather is expected to develop across all parts of the UK, but especially in the south. Temperatures rising through the middle part of the week to become above the September generally, and well above it in the south where 26C (78F) could be reached.
By the end of the week cooler and cloudier air will probably return from the north. There could be some patchy rain in northern and eastern areas, but generally it is expected to remain dry.
8/9 to 14/9
The emphasis during the early part of the week is likely to be on further dry weather. Temperatures mostly close to or slightly above the average, and still warmish in the south.
The second half of the week could see more unsettled conditions beginning to return from the west or south west and there is the potential for significant rainfall. However, confidence on the details are low with eastern and central Britain quite likely to keep a good deal of mostly dry and fine weather.
15/9 to 30/9
Forecast confidence for this period is low.
A transition in the weather is likely to develop with unsettled spells pushing in from the west at times. The driest and warmest conditions are still expected in the south with the north seeing the coolest and wettest weather. Overall this period temperatures are expected to be close to average in the north and slightly above average in the south.
Important note about long range weather forecasts: It is considered impossible to say with certainty what the weather will be like more than a few days ahead in the UK. Long range forecasts on TheWeatherOutlook have not been independently verified, and we make no claims for their accuracy. A range of factors including seasonal computer models, recent weather patterns, sea surface temperatures and teleconnections are considered when making the forecasts.
