1/8 to 7/8

Very warm.

Fine and very warm or hot weather is likely in the south and east for much of the week. In the north and west it will be changeable and cooler early on, but drier and warmer conditions are likely later on. In the south there is a possibility of it becoming very hot.

8/8 to 14/8

Very warm start but turning cooler. [Forecast confidence is moderate]

The southern half of the UK should have a good deal of fine weather, although there is a risk of showery rain or thunderstorms for a time. In the north there is a greater risk of rain early on but during the second half of the week it should become mostly dry. After a hot start temperatures dip in the south and in the north they will generally be closer to the seasonal average.

More changeable spells are likely at times but there should be good deal of dry and fine weather in the southern half of the UK. Showers or longer outbreaks of rain are forecast to be more frequent in the north, and particularly the north west. Temperatures generally remain above the average in the south and the possibility of hot periods remains. The north will generally be cooler.

Important note about long range weather forecasts: It is considered impossible to say with certainty what the weather will be like more than a few days ahead in the UK. Long range forecasts on TheWeatherOutlook have not been independently verified, and we make no claims for their accuracy. A range of factors including seasonal computer models, recent weather patterns, sea surface temperatures and teleconnections are considered when making the forecasts.
