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


Well Bob, England is a big place!
Here in Wokingham we last had 20C in March in 2017, 20.8 on 30th.
Before that, 20.4 on 20th in 2014. In fact, 20C in March has been seen
here 5 times since 1976, the highest being 21.3C in 1990 and 2012.
The 1990 occasion was on an unusually early 17th.
In the longer-term, the Wokingham series back to 1904 saw a total of
18 =20C in those 116 years, the highest being 22.6 on 29th in 1965
and 22.4 on 9th in 1948. That last was certainly exceptionally early, the
Monthly Weather Report states that the highest in the UK that day was
23.9 C at Wealdstone, Middlesex.
