The month ahead

The monthly outlook is based on output from various global forecasting models combined with our own analysis.

May: Mixed month

Close to average in the south, slightly below average in the north.

Close to average in the south east, above average in the north and west.



1/5 to 7/5

Mostly changeable or unsettled.

Changeable conditions are expected in all regions during the first few days of the month with showers or longer spells of rain pushing northeastwards. Generally chilly in the north with a risk of rain turning to snow over high ground. Becoming warmer in the south.

The generally mixed theme continues through the second half of the week. In southern regions drier and brighter spells are possible with more emphasis on showers or longer spells of rain in the north. Temperatures close to the seasonal average but feeling warm in the south during sunny spells.

8/5 to 14/5

Mixed but probably drier.

Across southern and central regions there should be quite a lot of dry and bright weather during the week. Despite this there is a risk of it being more changeable at times with showers or longer spells of rain. Possibly quite warm.

The north of the UK probably remains more unsettled with wet weather interspersed with drier intervals. Temperatures here close to the seasonal average.

15/5 to 31/5

Forecast confidence for this period is low.

Through the second half of the month quite unsettled weather is anticipated in the north but in the south there could be more focus settled spells.

In the south east drier and warmer periods are likely to develop and be interspersed with changeable or unsettled periods. Aggregated rainfall amounts probably close to the average. Close to or slightly above average temperatures are favoured.

In the north a wetter picture is expected with rainfall above average for the second half of May. Close to or slightly below average temperatures are favoured.

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.
