Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +0.79 °C in the more recent reference period; this unweighted mean describes the set of monthly averages, not a day-weighted annual average or daytime highs. The largest monthly increase was in May, with a difference of +1.26 °C.

Changes in rainfall

Mean daily rainfall averaged across calendar months had a difference of -0.05 mm/day, a small overall decrease between the reference periods. That aggregate does not mean rainfall fell in every month: the largest monthly decrease was in September, at -2.40 mm/day, while the largest increase was in November, at +2.47 mm/day. These are daily averages, not monthly rainfall totals, and they do not establish how often rain fell.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months had a difference of -0.34 hours/day. The largest monthly decrease was in July, at -1.00 hours/day, while April had the largest increase, at +0.17 hours/day; these monthly contrasts give more detail than the overall mean but do not describe every day’s sky conditions.
