Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature was higher by a difference of +1.12 °C in the more recent period; this is an unweighted comparison of monthly means, not a day-weighted annual average or a measure of daytime maximum temperatures. The largest monthly increase was in February, with a difference of +1.64 °C in monthly mean temperature compared with the earlier reference period. This identifies the strongest monthly increase, rather than implying that every month changed by the same amount.

Changes in rainfall

Averaged across calendar months, mean daily rainfall was higher by a difference of +1.99 mm/day in the more recent period. This is an unweighted average of monthly means, and describes daily amounts rather than monthly rainfall totals. The largest monthly increase in mean daily rainfall occurred in November, with a difference of +4.23 mm/day compared with the earlier reference period. In contrast, February had the largest monthly decrease, a difference of -1.13 mm/day; these extrema show that the average shift was not uniform across months.

Changes in sunshine duration

Mean daily sunshine duration, averaged across calendar months, was lower by a difference of -1.11 hours/day in the more recent period. This unweighted comparison of monthly means is not a day-weighted annual average. November recorded the largest monthly decrease in mean daily sunshine, with a difference of -2.10 hours/day compared with the earlier reference period. This marks the strongest monthly reduction and does not mean that every month had an equal decrease.
