UK long range weather forecast

There is an east-west split in conditions through the end of June, as the west is more likely to experience showers, heavy at times, and the east more likely to remain drier with some sunshine, although there is a chance of some showers here. Winds are expected to be moderate or strong at times, especially in the northwest. The unsettled conditions are likely to extend over more of the north of the country through the later part of the period, perhaps bringing longer spells of rain to these areas. Southern areas likely staying drier, although with the risk of showers remaining. Temperatures are expected to be near normal, locally warm in parts of the east and southeast.

Updated:

There is a good chance of more settled conditions prevailing through the middle and later part of July, although some northern areas may see spells of rain or showers at times, especially early in the period. These spells could extend across the country at times, but in general the south will see the best of the settled conditions. Temperatures are likely to be close to or a little above average initially but trending towards warmer conditions later, especially across the south.
