Updated: 04:00 (UTC) on Sun 7 Dec 2025

UK long range weather forecast

A continuation of a similar pattern to that seen through early December is anticipated, especially at first, as frontal systems from the Atlantic spread into and across the UK, interspersed with some temporary drier interludes. These will bring occasional spells of rain, which may be heavy at times bringing the risk of some impacts given how wet it has been lately. In addition, there may also be potential for some periods of strong winds at times too. Whilst it will often be mild, later in the period there may be a transition for temperatures to return closer to average, with a slightly higher chance of some wintry hazards across northern parts of the UK, especially on high ground.

Updated: 14:00 (UTC) on Sat 6 Dec 2025

Changeable conditions are expected across the UK during this period. Low pressure systems will probably dominate, meaning showers or longer spells of rain, heavy at times, for much of the UK and some hill snow in the north. Periods of strong wind are also possible, especially around coasts. Some drier, more settled spells are possible but how long these last is very uncertain. Temperatures will likely be close to average or slightly above overall.
