Updated: 16:00 (UTC) on Wed 3 Dec 2025

UK long range weather forecast

A continuation of the unsettled conditions seen recently is expected, with further showers or longer spells of rain and some strong winds affecting all parts. This period will likely start largely fine, bar a few showers, but another area of rain and strong winds is expected to move northeast across all parts early next week, followed by sunny spells and some showers. However, further bands or areas of rain are likely to move east or northeast across all parts over the following several days, some of these accompanied by potentially very strong winds. Temperatures will generally be near or a little above average, but feeling cool in the wind and rain. Little in the way of frost, fog and snow is expected in this unsettled spell.

Updated: 14:00 (UTC) on Wed 3 Dec 2025

This period is likely to be changeable, with further spells of rain or showers and some strong winds at times, especially in the west. Hill snow is also a possibility, mainly in the north. However, there is a greater chance of spells of high pressure during this period, bringing more in the way of dry weather compared to the unsettled conditions we are likely to see through the first couple of weeks of December. This will increase the chances of overnight fog and frost. Overall, near or slightly above average temperatures are most likely, though some colder spells are also possible, especially should any prolonged settled spells develop.
