The last record involving the number of days reaching 20°C dates from 1959. In that year this temperature was reached on at least 131 days.
Weatherman Frank Deboosere: "The trashing of all these old records means that we are evolving towards a warmer climate."
During an average year 87 days with highs of 20°C or more are recorded. This figure is based on records dating from 1981. Since 2000 there have been far more years with more warm days than average.
