Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +1.63 °C compared with the earlier reference period. This is an unweighted mean of the monthly means, not a day-weighted annual average, and it describes the aggregate rather than a change in every month. The largest monthly increases in mean temperature were in September / October, each with a difference of +2.22 °C; these monthly means are not daytime maximum temperatures.

Changes in rainfall

Averaged across calendar months, mean daily rainfall had a difference of -1.62 mm/day compared with the earlier reference period. This unweighted average of monthly means describes a broad shift in daily amounts, not a change that necessarily occurred in every month; the figures are daily means rather than monthly totals. The largest monthly decrease was in December, with a difference of -4.85 mm/day, highlighting a particularly pronounced monthly change without implying that the same decrease applied throughout the year.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months had a difference of +0.50 hours/day in the more recent period. This is an unweighted mean across monthly means, rather than a day-weighted annual average, so it summarizes the overall monthly pattern without implying that sunshine increased in every month. The largest monthly increase was in December, with a difference of +1.58 hours/day; by contrast, August had the largest monthly decrease, at -0.04 hours/day. Together, these monthly extremes show that the aggregate increase was not uniform across the calendar months.
