UK long range weather forecast

Still fine for many at the start of this period but by Friday and into the weekend, there is an increasing likelihood that rain or showers will start to arrive from the south or west. Wetter weather will probably spread to all areas, at least for a time and could be accompanied by strong winds at times. Into the following week, unsettled conditions will probably continue across many parts of the UK. Some heavy rain or showers are possible at times, these most likely across southern parts of the country. Temperatures are likely to be widely above average at the start of this period before probably falling back and then fluctuating around average for the remainder of the period.

Updated: 14:00 (UTC) on Sun 16 Mar 2025

Confidence is low, but blocked patterns are most probable for the first half of April. This can lead to slow-moving areas of low and high pressure and, depending on their location, can result in extended periods of either dry conditions or, perhaps more likely, wetter episodes in the form of rain or showers. Either way, whilst temperatures overall may be near average, given the time of year this type of regime tends to increase the chance of periods of below average temperatures at times.
