UK long range weather forecast

Next week, high pressure is set to dominate the UK, bringing a lot of dry weather. Some places may start in fog, and this could be slow to clear, or possibly linger all day. Elsewhere, cloud amounts will be variable, but there should be plenty sunshine in many places. For most, temperatures look to be fairly close to normal for the time of year, though it will remain chilly through the day where any fog lingers and the sun fails to break through. Some overnight frost is likely where skies are clear and winds remain light. As we head into the following week, there are signs that more unsettled weather may return, but confidence surrounding this change is low.

Updated: 13:00 (UTC) on Thu 29 Oct 2026

During the second half of November, there is an increasing chance of more unsettled conditions developing, which would mean spells of rain and the potential for strong winds at times. The extent and location of the wettest and/or windiest areas are uncertain at this range, but the wettest and windiest conditions are most likely in the north and west, with relatively drier conditions towards the south and east. Overall, temperatures will probably be near or a little above normal for the time of year.
