Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +0.84 °C in the more recent period; this is an unweighted mean of monthly means, not a day-weighted annual average, and it describes the aggregate rather than every month. It is also a measure of monthly mean conditions, not daytime maximum temperatures. The largest monthly increase was in March, with a difference of +1.33 °C compared with the earlier reference period.

Changes in rainfall

Averaged across calendar months, mean daily rainfall has a difference of +0.85 mm/day in the more recent period. This unweighted average of monthly means describes an overall comparison, not the change in every month; the figures are daily means rather than monthly rainfall totals. The largest monthly increase in mean daily rainfall occurred in November, with a difference of +3.15 mm/day. In contrast, the largest monthly decrease was in October, with a difference of -1.07 mm/day compared with the earlier reference period.

Changes in sunshine duration

Averaged across calendar months, mean daily sunshine duration shows a difference of -0.63 hours/day in the more recent period. This is an unweighted mean across monthly averages, so it summarizes the calendar months collectively rather than indicating the change in each month. The largest monthly decrease was in November, with a difference of -1.38 hours/day. The largest monthly increase, by comparison, occurred in March, with a difference of +0.03 hours/day; these monthly changes show that the average shift was not identical across months.
