Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +1.08 °C compared with the earlier reference period. This is an unweighted average of the monthly means, not a day-weighted annual figure, and it describes the aggregate rather than implying that every month changed by the same amount. The largest monthly increase was in November, with a difference of +1.72 °C. These are monthly mean temperatures, not daytime highs.

Changes in rainfall

Mean daily rainfall averaged across calendar months had a difference of +2.04 mm/day in the more recent period. This unweighted average summarizes the monthly means; it is not a monthly rainfall total or a day-weighted annual average, and it does not mean rainfall increased by that amount in every month. The largest monthly increase occurred in May, with a difference of +5.91 mm/day. By contrast, February had the largest monthly decrease, a difference of -0.13 mm/day. These monthly comparisons describe mean daily amounts rather than accumulated totals.

Changes in sunshine duration

Mean daily sunshine duration, averaged across calendar months, had a difference of -0.53 hours/day compared with the earlier reference period. This unweighted mean summarizes the monthly averages rather than describing a day-weighted annual total or establishing the same change in each month. The largest monthly decrease was in March, with a difference of -0.96 hours/day. Both comparisons concern average daily hours, not total sunshine accumulated over a month.
