April was a predominantly unsettled month, with little in the way of consistent warmth, especially over England, and hence the advance of spring seemed to be rather slow, though it was more settled for a time around mid-month, this being followed by a return to rather chilly conditions.
Although, temperatures fluctuated somewhat throughout April the average is close to or a little below average for the month overall, with Northern Ireland warmest relative to average. A milder spell mid-month was balanced by rather colder conditions towards the end of the month.
