The month ahead

The monthly outlook is based on output from various global forecasting models combined with our own analysis.

September weather: Reasonable 

Issued 01/09/2016


Above average.


Below average in the south, close to average in the north.



1/9 to 7/9


Wet weather affects all regions and there is the potential for heavy rain even in the south during the middle part of the week. Through the second half of the week it remains quite unsettled in the north but drier and warmer weather begins to return to the south. By the end of the period it could be very warm in southern and central areas.

8/9 to 14/9

Mostly fine in the south.

Southern counties have a good deal of dry and very warm weather with sunny periods developing widely. In the north a more changeable picture persists but even here drier and warmer spells are probable. Towards the end of the week the risk of rain may also increase in the south.

15/9 to 30/9

More changeable. [Forecast confidence is low.]

During this period progressively more unsettled weather is forecast to push southwards. The driest and warmest conditions are still likely to be in the south with the north having cooler and wetter spells. Overall temperatures will probably be close to the seasonal 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.
