Overview of climate changes

Temperature changes

The unweighted mean difference across calendar-month temperature means was an increase of +1.54 °C; this summarizes the monthly means rather than daytime maximum temperatures, and does not mean every month changed by the same amount. The largest monthly increases were shared by February / April, each with a difference of +2.39 °C compared with the earlier reference period.

Changes in rainfall

Averaged across calendar months, mean daily rainfall had a difference of -0.07 mm/day, a decrease in the more recent period; this is an unweighted mean of monthly means, not a day-weighted annual average or a monthly total. The largest monthly decrease was in January, with a difference of -0.77 mm/day in mean daily rainfall. By contrast, November had the largest monthly increase, a difference of +0.49 mm/day; these month-specific shifts do not describe every month's rainfall.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months showed a difference of -0.16 hours/day, a decrease in the more recent reference period. This is an unweighted average of monthly means, rather than a day-weighted annual figure. The largest monthly decrease was in June, with a difference of -0.41 hours/day. In January, sunshine instead had the largest monthly increase, a difference of +0.22 hours/day; these daily-hour differences describe the monthly averages, not every day.

Changes in snowfall

The unweighted mean difference in mean daily snowfall, averaged across calendar months, was 0.00 mm/day at the displayed precision. That rounded equality does not establish that snowfall was absent or that no finer-scale differences occurred. The largest monthly decrease was in January, with a difference of -0.06 mm/day in mean daily snowfall. This is a daily mean difference, not a monthly snowfall total.
