14 day UK weather forecast

Autumnal weather arrives

UK outlook issued Thursday 23rd September 2021

Week 1

Warm start then autumn arrives. 

Friday: Western parts of the UK have some showery rain. Elsewhere it will be dry with sunny periods. Windy in the north. Very warm for late September in southern and central regions. 

Saturday: Showery rain pushes eastwards mostly across the northern half of the UK. Southern and central regions could see an odd shower, but there should be a good deal of dry and bright periods. Generally quite warm.

Sunday: Early in the day there may be scattered showers and in the south east an odd heavy one is possible. Through the day wet and windy conditions push eastwards across Northern Ireland and into western Britain. Central and eastern areas should have a mainly dry afternoon with warm sunny spells.  

Monday, Tuesday, Wednesday, Thursday: A band of cloud and rain clears eastwards at the start of the period. All regions then have quite unsettled conditions with wet and windy spells. However, there probably will still be a reasonable amount of dry weather in the south. Temperatures quite close to the seasonal average.

Forecast confidence is high falling to medium.



Week 2


Changeable or unsettled weather is forecast to continue through the week. All areas could see showers or longer spells of rain and at times it turns windy. The driest and mildest conditions are expected to be in the south east, with more frequent spells of rain and lower temperatures in the north west.

Forecast confidence is low.


Week 1

High pressure has a lot of influence through the first few days but by Sunday a change begins to take place. Active weather fronts push in from the west and they herald a switch to a more autumnal pattern for the rest of the week.

Week 2

Computer models are suggesting an Atlantic flow will be established over the UK. Disturbances push eastwards across all regions, but ridges of high pressure have some influence too, especially in the south.
