Overview of climate changes

Changes in rainfall

Mean daily rainfall averaged across calendar months had a difference of +1.52 mm/day in the more recent period. This is an unweighted summary of monthly mean daily amounts, not an annual total or a month-by-month pattern shared throughout the year. The largest monthly increase occurred in September, with a difference of +3.68 mm/day; the largest monthly decrease was in March, with a difference of -0.24 mm/day. These figures describe daily rainfall averages within the relevant months, not monthly rainfall totals.

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +0.52 °C compared with the earlier reference period; this unweighted mean summarizes the monthly means rather than a day-weighted annual average, and it does not imply the same change in every month. The largest monthly increase was in February, with a difference of +1.78 °C. In contrast, June had the largest monthly decrease, a difference of -0.28 °C. These are changes in monthly mean temperature, not daytime maximum temperatures.

Changes in sunshine duration

Mean daily sunshine duration, averaged across calendar months, shows a difference of -0.44 hours/day compared with the earlier period. This is an unweighted comparison of monthly means, not a day-weighted annual average, and does not mean that daily sunshine changed by the same amount in every month. The largest monthly increase was in March, with a difference of +0.18 hours/day. The largest monthly decrease occurred in June, a difference of -0.92 hours/day; this contrast illustrates how monthly differences can vary around the overall mean.
