Summer 1991 & Summer 1992 are the mirror image of each other, 1991 started cool and ended up hot, and 1992 started hot and ended up cool.
1991
May: Dull and very dry (CET 10.
June: Cold, dull and wet (CET 12.1)
July: Changeable and warm (CET 17.3)
August: Sunny, warm and very dry (CET 17.1)
September: Very warm and sunny (CET 14.7)
1992
May: The warmest of the century, with violent thunderstorms at the end (CET 13.6)
June: One of the warmest of the century, mainly dry and sunny (CET 15.7)
July: Cloudy and wet (CET 16.2)
August: Very wet and windy (CET 15.3)
September: Cloudy, cool and unsettled (CET 13.4)
June & July 1991 is an amazing difference between very cool and very warm, the only time I can think of 2 completley different consecutive months is the difference between a very cold January and a very mild February in 1945, can anyone think of a more extreme difference between 2 consecutive months.
Summer 1992 must have been a real disappointment in the end, especially after the way it started.
