March weather: Changeable with some cold spells

Forecast issued 01/03/2021


Close to or slightly below average.


Slightly below average.

1/3 to 7/3

Settled and turning cold.

After a dry start showery spells of rain push across southern and possibly central regions. In the north temperatures begin to fall during the middle of the week and the colder air then spreads southwards across all regions. Wintry showers develop, particularly in eastern regions with sleet or snow falling down to low levels at times. By the end of the week it should become dry in all regions with the possible exception of the far north west where patchy rain could return. Nighttime frosts will be widespread and sharp in places.

8/3 to 14/3

Becoming unsettled. [Forecast confidence is low to moderate]

A dry and settled start is expected in southern and central regions. In the north and particularly the north west there is a growing risk of rain. Temperatures in the south will be close to the average but in the north it turns milder for a time. Through the week the unsettled conditions spread southwards bringing showers or longer spells of rain in all regions. Colder incursions become likely in the north and there is the possibility of sleet or snow at times, particularly over high ground.

15/3 to 31/3

Mixed. [Forecast confidence is very low]

Close to average temperatures are forecast when taken over the period as a whole and in the south during drier spells it may feel quite warm. Mixed weather is expected, with showers or longer outbreaks of rain spreading across the whole of the country on occassion. Despite that drier periods are likely too, particularly later on.
