Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +1.22 °C in the more recent period; this unweighted comparison describes the average of the monthly means, not a day-weighted annual average or daytime maximum temperatures. The largest monthly increase was in December, with a difference of +2.09 °C compared with the earlier reference period. This identifies the strongest increase among the supplied monthly temperature differences, rather than implying that every month warmed by the same amount.

Changes in rainfall

Averaged across calendar months, mean daily rainfall had a difference of +0.02 mm/day in the more recent period. This is an unweighted average of calendar-month means, not an annual total or a measure of how rainfall changed on every day. The largest monthly increase in mean daily rainfall occurred in February, with a difference of +0.13 mm/day. In contrast, November had the largest monthly decrease, with a difference of -0.06 mm/day; these monthly differences describe daily averages, not monthly rainfall totals.

Changes in sunshine duration

Averaged across calendar months, mean daily sunshine duration had a difference of -0.17 hours/day compared with the earlier reference period. This unweighted mean summarizes calendar-month averages and should not be read as a change applying equally to every day or month. The largest monthly decrease in mean daily sunshine duration was in February, with a difference of -0.36 hours/day. It marks the strongest decrease among the supplied monthly sunshine differences, rather than a uniform change throughout the year.
