Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +2.03 °C compared with the earlier reference period. This is an unweighted mean of monthly means, not a day-weighted annual average, and it describes average conditions rather than daytime maximum temperatures. The largest monthly increase was in December, with a difference of +3.40 °C; that month-specific result does not mean every month changed by the same amount.

Changes in rainfall

Mean daily rainfall, averaged across calendar months, shows a difference of -1.33 mm/day compared with the earlier reference period. This unweighted mean of monthly means is not a day-weighted annual average, and the daily measure should not be read as a monthly rainfall total. The largest monthly decrease occurred in May, with a difference of -2.68 mm/day. That is a month-specific contrast between reference periods, not a description of every day or every month.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months shows a difference of +0.32 hours/day compared with the earlier reference period. This is an unweighted mean of monthly means, rather than a day-weighted annual average. The largest monthly increase was in July, with a difference of +1.05 hours/day, while the largest monthly decrease was in April, with a difference of -0.45 hours/day. These month-specific contrasts show that the overall mean does not describe the change in every month; they refer to mean daily hours, not total sunshine accumulated over a month.
