May 2021 was generally wetter, colder and cloudier than average across most of the UK. It was particularly wet across Wales, Devon and parts of central northern England, but drier in the far north and northwest of Scotland. It was the fourth wettest may since 1862 and the wettest since 1967 in the UK. Mean temperatures were around a degree or more below the LTA across the UK, and would have been a shade colder if it wasn’t that May finished with a warm flourish. It was the coldest May since 1996 in the UK as a whole. It was a dull month across the UK with only 86% of the average sunshine apart from the exception of Northern Ireland and the Isle of Man which had slightly above average sunshine.
