We compare the forecast with the climate average for exactly the same calendar days, calculated from 60 years of observations. The difference shows how the coming month compares with a typical one.
These are real historical extremes recorded in Colston Bassett since 1960: the highest and lowest temperature for each calendar date, with the year it happened.
