September weather: Unsettled periods

Forecast Issued 03/09/2017

Temperature

Close to average.

Precipitation

Above average in the north west, close to average in the south east.

 

 

1/9 to 7/9

Changeable but drier days in the south.

A changeable theme is expected to continue through the week. Showers or longer spells of rain are likely to be most frequent in the north and west. The south and east has drier periods but even there wet weather develops at times. Temperatures will often be on the low side in the north but in the south it becomes quite humid for a time.

8/9 to 14/9

Unsettled.

A spell of very unsettled weather is forecast to develop early in the week. All regions then have showers or longer spells of rain. It could become very windy at times with the possibility of gales or even severe gales. Feeling quite chilly for much of the period.

15/9 to 30/9

Mixed. [Forecast confidence is low]

The north remains more changeable with showers or longer spells of rain, and windy conditions at times. The southern half of the UK has quite a lot of dry weather and there is a chance of it becoming warm at times, but even there more changeable spells probably bring a risk of some rain. Temperatures generally close to the average but perhaps 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.
