Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +1.72 °C compared with the earlier reference period. This is an unweighted average of the monthly means, not a day-weighted annual average, and it describes mean temperature rather than daytime maximum temperatures. The largest monthly increase in mean temperature occurred in April, with a difference of +2.99 °C. This identifies the strongest monthly increase in the supplied comparison; it does not imply that every month warmed by the same amount.

Changes in rainfall

Averaged across calendar months, mean daily rainfall had a difference of -2.38 mm/day. This is an unweighted average of monthly means, not a day-weighted annual figure, and the daily measure should not be read as a monthly rainfall total. The largest monthly decrease in mean daily rainfall was in July, with a difference of -13.80 mm/day. By contrast, the largest monthly increase was in September, with a difference of +0.45 mm/day. These are the most pronounced changes in opposite directions among the supplied monthly comparisons, not a description of every month.

Changes in sunshine duration

Averaged across calendar months, mean daily sunshine duration had a difference of +0.50 hours/day compared with the earlier period. This unweighted average of monthly means describes daily sunshine hours, rather than a day-weighted annual total. The largest monthly increase in mean daily sunshine duration occurred in July, with a difference of +2.53 hours/day. The largest monthly decrease was in December, with a difference of -0.24 hours/day; these contrasting monthly changes show why the across-month mean should not be taken to represent every month.
