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.

Forecast overview

The first half of the meteorological spring is expected to be quite cold with slightly below average precipitation levels. The second half brings warmer and wetter conditions relative to the climatological norm.

Temperature

Temperatures are forecast to be slightly below the long term average over the three month period.

Precipitation

Over the three month period rainfall levels are forecast to be close to average.

March

Temperature:

Below average.

Precipitation:

Slightly below average.

First half

The month starts with exceptionally cold weather and widespread snow. Less cold air steadily returns across southern areas and filters northwards during the middle and second half of the first week. Precipitation becomes progressively more likely to fall as rain but in the north snow remains possible. During the second week rather changeable conditions continue. Northern areas probably stay quite cold and in the south temperatures could drop after a milder start.

Second half

Temperatures in the north are expected to be below the average for much of the period but at times the south becomes milder. All regions have an above average risk of nighttime frosts over the period as a whole. In the north further spells of rain and snow are expected. In southern counties rain is more likely but snow remains a possibility.

 

 

April

Temperature:

Slightly below average.

Precipitation:

Close to average.

First half

The first half of the month is expected to bring rather unsettled and chilly conditions with heavy showers or longer spells of rain. At times the showers could be wintry and snow remains a possibility, especially in the north. Overnight frost continues to be a risk. 

Second half

The second half of the month probably starts off with unsettled conditions and close to average temperatures. This gives a mix of sunshine and showers, as well as more persistent spells of rain. Showers could be heavy and thundery. Later on the chances of warmer and drier days increases, particularly in the south.

May

Temperature:

Slightly above average.

Precipitation

Slightly above average.

First half

Rather changeable weather is expected early in the month with showers or longer spells of rain and close to average temperatures. Towards the middle of the month increasingly dry and warmer conditions are more likely, especially in the south and east.

Second half

The second half of the month is expected to bring warmer than average conditions, with a good deal of dry and increasingly sunny weather. Northern areas may well be less settled and cooler at times with showers or longer spells of rain.
