I noted in my diary that the frost of May 31st was the latest on record
for Kew, I also in Woodford Green suburban Essex clocked a minimum of 0c
on that morning.
On the famous June 2nd morning my min was 3c and during
a violent squall between 1015-1115 some sleet was seen. By 11pm that
night it was down to 4c with a strong Northwest wind blowing.
To say that it was then followed by quite a good summer is somewhat of
an understatement !, June was one of the sunniest months on record for
London and it was the best summer for 16 years, following the abysmal
run from 1959.
