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.

Overview
A reasonably average spring is expected overall both in terms of rainfall and temperature. Early in the period rather cold conditions are likely at times with little indication for anomalous early season warmth. Despite this recent seasons have generally brought above average temperatures and the expectation is for spring to follow this pattern.

Temperature
Slightly above average.   


Precipitation
Close to or slightly below average.  

March
Temperature:
Close to average 
Precipitation:
Slightly below average

The first few days of the month are expected to bring quite cold and showery conditions. The showers are likely to be heavy and wintry at times with a risk of snow, particularly in the north and west. Over higher ground significant accumulations of snow are probable.  A ridge of high pressure should bring a drier interlude for a time during the second half of the week but this isn’t expected to last for long with cloud and rain returning off the Atlantic to the north west and then spreading south eastwards over all of the UK.

During the second week of the month high pressure is expected to build over or close to the UK bringing a trend towards drier weather. The most settled conditions are expected in the south with rain remaining more likely in the north west.  Nights could be quite cold with a risk of frost.

The second half of the month is likely to start off mostly dry across much of the country but perhaps more changeable in the north west. Temperatures at this stage possibly close to average by day but below average by night with a risk of patchy frost. Later in the period rather changeable conditions might extend  further south and east with rain or showers affecting  all regions.

April
Temperature:
Slightly above average

Precipitation:
Slightly above average

The first half of the month is expected to bring mixed weather with heavy showers or more persistent outbreaks of rain at times. Temperatures varying significantly with colder and milder than average spells. It may still be cold enough at times for showers to turn wintry in the north with sleet or snow over higher ground. Occasional overnight frost is also likely.

The second half of the month will probably see changeable conditions but temperatures over the period as a whole are expected to be slightly above the seasonal average. As the forecast period progresses there may be an increasing chance of drier and warmer spells of weather developing, particularly in southern and central regions.

 

May
Temperature:
Slightly above average 
Precipitation:
Slightly below average

The first half of the month is expected to bring warmer than average conditions, with a good deal of sunshine, but also heavy showers. Northern areas possibly cooler and wetter at times.

The second half of the month is expected to see temperatures close to or slightly above average over the period as a whole. Mixed  conditions are expected but drier and warmer spells are likely at times, particularly in the south.
