May weather: Fine and warm period then mixed

Forecast Issued 01/05/2018


Above average.


Slightly below average.


1/5 to 7/5

Warmer and drier later.

All regions have mixed weather during the first few days with showers or longer periods of rain but also drier and brighter spells. After a cold start temperatures return towards the seasonal average. During the second half of the week it becomes much warmer and drier in the south. The north remains more changeable but the chance of warmer and drier days increases.

8/5 to 14/5

Warm start. [Forecast confidence is low]

Fine and warm weather is expected in most of the UK early in the week, although there could be a few thundery showers in the south and the far north west may be more changeable. Later on more changeable conditions could extend across much of the north and west but the south and east should be mostly fine and warm.

15/5 to 31/5

Warm start but more changeable. [Forecast confidence is low]

A good deal of dry and warm weather is expected during the first few days in the south and east but the risk of rain remains higher in the north and west. Through the rest of the period a more changeable pattern spreads southeastwards across most of the country. Temperatures probably become close to the seasonal average.

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.
