The minimum last night here in Coulsdon of 14.2C has only once been exceeded
in the whole of May since my station was established in 1979 and that was
May 2000. However this was a mid month occasion with 15.0C so to have one's
second highest value on the 1st covering a period of over a quarter of a
century is quite remarkable. This follows on from yesterday's record
breaking April minimum.
However in 1922, Addington an official station about 4 miles to the north
east of Coulsdon, recorded a minimum of 18.3C on the 22nd at a time when day
maxima were around 32C across London. Last night's min was significant in
that it was so early for such high values.
Also heard a peal of thunder at 09.00hrs this morning. Yesterday was my
first view of the thundery castellanus cloud which is very often followed by
thunder within 24 hours.

I don't agree with your use of the work 'extraordinary', these types of
above average temperatures are now occuring on such on such a regular
basis that I wouldn't call them 'extraordinary'.
