When did England last get to the end of March without reaching 20 degrees?

No idea but 20C here in March is not that common as the sea is still too
cool and inevitably on a sunny March day, a sea breeze will spark up
late morning and peg the temperature back to the mid to high teens
rather than +20C, despite the strong spring sunshine.

The last time I reached +20C here was in 2012 with 21.6C on the 29th.

There have only been 3 March days since 2005 that I have recorded 20C or
higher.

So far this March has been drier, slightly warmer and rather cloudier
than normal.

1st - 27th
Mean minimum = 3.6C
Mean maximum = 12.5C
Mean = 8.1C
Rain = 37.6 mm
Sunshine = 104.4 hours
