Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +0.90 °C compared with the earlier reference period; this is an unweighted mean of monthly means, not a day-weighted annual average or a measure of daytime highs. The largest monthly increase in mean temperature occurred in April, with a difference of +1.21 °C. This identifies the strongest increase among the supplied monthly comparisons, rather than describing every month.

Changes in rainfall

Averaged across calendar months, mean daily rainfall had a difference of -1.18 mm/day compared with the earlier reference period. This is an unweighted average of monthly mean differences, not a day-weighted annual average, and daily amounts should not be read as monthly totals. The largest monthly decrease in mean daily rainfall was in September, with a difference of -4.42 mm/day. By contrast, July had the largest monthly increase, at a difference of +0.50 mm/day; these are the most pronounced changes in opposite directions among the supplied monthly comparisons.

Changes in sunshine duration

Averaged across calendar months, mean daily sunshine duration had a difference of -0.23 hours/day compared with the earlier reference period. This unweighted mean summarizes the monthly averages and does not imply that sunshine changed by the same amount in every month. The largest monthly decrease in mean daily sunshine duration occurred in July, with a difference of -0.78 hours/day. In April, the largest monthly increase was a difference of +0.18 hours/day, showing that the monthly comparisons were not uniform in direction.
