About this forecast

Consistently accurate long range forecasts for the UK are not possible with current technology.

Use this page to try and identify trends. For example, are the summer months showing long settled spells or the winter months cold ones. Is the forecast consistent from day to day or is it changing dramatically? If it is the former then confidence could be higher.

Don't rely on the forecast shown here but have fun using it!

Data from the the Climate Forecast System v2 (CFSv2) model is used.
