May forecast

The month ahead

Transition to summer

May is the last month of the meteorological spring and often brings an early taste of summer. The spring to date has been mild, and the April Central England Temperature (CET) finished close to 9C which is just over 1C above the average. Despite this it was colder late in the month with snow in parts of the north. Can we expect the late April chill to remain or is a transition to full blown summer weather looking likely in May?

Warming up in May

Current indications suggest a settled start to the month as high pressure becomes centred to the north of the UK. This will lead to an easterly flow across the country with the highest temperatures in the west. At times in the east it is expected to be cooler and there is a risk of showery rain pushing in from the North Sea. There are signs of a more unsettled spell developing during the middle part of the month and this may bring some rain. That would probably be welcomed by farmers and growers.

Confidence in the outlook for the second half of the month is low. After an unsettled start it could turn warmer and drier.
