There were several recordings of 30C+ in 2009, infact 30C was officially reached somewhere in England in all three summer months, which must of been the last summer to do so.
June 2009: 31.8C in Wisley, Surrey
July 2009: 32C in Hampton, Greater London
August 2009: 30.3C in Gravesend, Kent
(Thanks to Met Office data)
Interestingly only 3 days here so far have reached/ gone above the average maximum of 22C so far this July.
How many degrees below the average maxima out of interest for July would it take for a day to be classed 'exceptionally cool'?
