Overview of climate changes

Temperature changes

The unweighted mean difference across calendar-month temperature means is a difference of +1.68 °C; this summarizes the months collectively, rather than indicating the change in every month. The figures are monthly means, not daytime maximum temperatures. The largest monthly increase was in December, with a difference of +4.39 °C compared with the earlier reference period. The largest monthly decrease was in May, at a difference of -0.35 °C in the more recent period.

Changes in rainfall

Averaged across calendar months, mean daily rainfall had a difference of +1.02 mm/day in the more recent period. This is an unweighted summary of monthly means, not a day-weighted annual average or a monthly rainfall total. The strongest monthly increase was in March, at a difference of +2.32 mm/day. By contrast, October had the largest monthly decrease, a difference of -1.22 mm/day. These monthly comparisons describe mean daily amounts, not total rainfall accumulated during either month.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months had a difference of -0.11 hours/day between the reference periods; the mean summarizes the monthly values rather than describing every month. In October, the largest monthly increase was a difference of +0.51 hours/day. The largest monthly decrease occurred in May, with a difference of -0.60 hours/day compared with the earlier reference period.

Changes in snowfall

Across calendar months, the unweighted mean difference in mean daily snowfall was a difference of -0.58 mm/day in the more recent period.

The largest monthly decrease was in January, at a difference of -3.61 mm/day. The largest monthly increase occurred in April, with a difference of +0.15 mm/day; both comparisons concern mean daily snowfall.
