Questions about the month ahead

How accurate is a month-long forecast?

What does "above average" mean?

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.

Where do the 66-year records come from?

These are real historical extremes recorded in St Mary Hill / Eglwys Fair y Mynydd since 1960: the highest and lowest temperature for each calendar date, with the year it happened.
