Overview of climate changes

Temperature changes

Monthly mean temperature was higher by a mean difference of +1.44 °C averaged across calendar months in the more recent reference period. This is an unweighted mean across monthly means, not a day-weighted annual average, and it describes the comparison between periods rather than a continuous trend. The largest monthly increase was in May, with a difference of +2.22 °C compared with the earlier reference period. These are monthly mean temperatures, not daytime maximum temperatures.

Changes in rainfall

Mean daily rainfall had a mean difference of -0.88 mm/day averaged across calendar months in the more recent period. This unweighted comparison of monthly means is not a day-weighted annual average, and it does not mean that rainfall decreased in every month. The monthly contrasts were uneven: May had the largest decrease, a difference of -2.68 mm/day, while January had the largest increase, a difference of +0.39 mm/day. These figures describe mean daily rainfall, not monthly totals.

Changes in sunshine duration

Mean daily sunshine duration showed a mean difference of -0.19 hours/day averaged across calendar months in the more recent period. This is an unweighted comparison of monthly means, not a day-weighted annual average, and does not imply the same change in each month. Monthly differences varied: July recorded the largest decrease, a difference of -0.74 hours/day, whereas May recorded the largest increase, a difference of +0.34 hours/day. Both figures refer to mean daily sunshine hours.
