September weather: Close to average

Forecast issued 01/09/2020


Close to or slightly below average.


Close to average.

1/9 to 7/9


The south has dry and bright weather to begin with but in the north it will be wet and windy. Through the middle of the period patchy outbreaks of rain clear southwards and showery conditions follow. By the end of the week it should become mostly dry in the south and in sunny spells it feels warm. In the north west there is a risk of more persistent outbreaks of rain returning from the west.

8/9 to 14/9

Often fine in the south. [Forecast confidence is moderate falling to low]

Most of the UK has a good deal of dry and sunny weather during the first few days, although the risk of rain remains in the north west. It is likely to become warm for a time, particularly in the south and east of Britain. Later on it turns more unsettled in the north with spells of rain. Southern counties continue to have mainly dry conditions, although the possibility of some rain is not ruled out.

15/9 to 30/9

More unsettled. [Forecast confidence is very low]

Unsettled weather in north western areas spreads southeastwards across all of the UK bringing rain at times. Despite that there should continue to be a reasonable amount of dry periods too, particularly in the south. Temperatures are expected to be slightly below the average on the whole but it could turn warm at times in the south east.
