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

Rather mixed conditions are forecast in much of June and July. August is expected to be the most settled month. Nonetheless, a warmer than average summer with a reasonable number of fine periods is favoured.


Above the 30 year average taken over the three month period as a whole.


Close to average over the three months.



Close to average.


Close to average.

First half

Warm and dry conditions are replaced by cooler, showery and windy ones from the north. In central and northern counties ground frost becomes a risk in sheltered areas. Showers or longer outbreaks of rain are most likely in the north and east with snow possible over the Scottish mountains. During the second half of the period rather changeable conditions are predicted to continue, at least for a while. Some rain is probable but there should be drier and warmer intervals too..

Second half
Possibly still rather mixed early on but the trend is towards a more settled and warmer theme. Despite that there remains a risk of showery spells of rain, especially in the north and west. The south and east should have the highest temperatures and driest conditions, but even there some rain is likely.





Slightly above average.


Slightly above average.

First half

Mixed weather, although the emphasis may well be on drier and warmer conditions, especially in southern regions. Temperatures on the whole will probably be above the seasonal average.

Second half

Becoming increasingly unsettled with the likelihood of some heavy and thundery rain. However, some drier and very warm spells are likely too. Temperatures slightly above the seasonal average overall, but significant variations are expected as hot and humid continental air feeds into the UK on occasion.



Above average.


Below average.

First half

A higher than normal chance of drier and sunnier conditions is forecast. At times it could be very warm or hot. Thundery breakdowns mean rainfall amounts may  vary significantly but overall they are expected to be below the average.

Second half

A good deal of fine weather is favoured. However, more changeable spells are possible later. Very warm at times, but temperatures possibly dip towards the average near the end of the period.
