Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +0.62 °C in the more recent period. This is an unweighted comparison of monthly means, not a day-weighted annual average, and it describes the aggregate rather than a uniform change in every month. The largest monthly increase was in May, with a difference of +1.13 °C compared with the earlier reference period. These figures concern monthly mean temperature, not daytime maximum temperatures.

Changes in rainfall

The unweighted mean difference in mean daily rainfall, averaged across calendar months, was +0.01 mm/day. This is a comparison of daily averages by calendar month, not monthly rainfall totals, and the small aggregate difference does not imply the same change in each month. Monthly differences varied in direction: July had the largest increase, a difference of +1.86 mm/day, while November had the largest decrease, a difference of -1.71 mm/day. These are changes in mean daily rainfall, not changes in monthly totals.

Changes in sunshine duration

Averaged across calendar months, mean daily sunshine duration had a difference of -0.62 hours/day in the more recent period. The unweighted mean summarizes the month-by-month averages; it is not a day-weighted annual figure and does not mean every month changed by the same amount. The largest monthly decrease was in December, where the difference was -1.65 hours/day. This monthly result stands out within the supplied comparisons, but does not establish a continuous change between the reference periods.
