Long range weather forecast

This long range forecast for the UK is updated once a month. Using the latest long range data from the NCEP and then run through custom software here at Netweather it is on the cutting edge of technology for long range weather forecasting. It is important to bear in mind that forecasting at this range is still in its infancy so can effectively be considered experimental.

Summer 2015

Updated June 30th 2015
Looking ahead to the final month of summer, and of course the key, peak summer holiday period, then further ahead as we move into Autumn.

For a forecast for the next 4 weeks, please take a look at the monthly forecast.

August
Pressure is expected to be slightly higher than average across the bulk of the British Isles, along with a good deal of Europe during August. This is likely to lead to a warmer than average month across the British Isles, rainfall is currently forecast to be close to normal for the bulk of the UK, but the northwest of Scotland may buck that trend with wetter than average conditions possible here.
