Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +0.98 °C compared with the earlier reference period; this is an unweighted comparison of monthly means, not a day-weighted annual average or a measure of daytime highs. The largest monthly increase was in March, with a difference of +2.16 °C. By contrast, September had the largest monthly decrease, a difference of -0.24 °C. These monthly extremes show that the overall mean difference did not apply uniformly across the calendar months.

Changes in rainfall

Mean daily rainfall, rather than monthly rainfall totals, had an unweighted difference across calendar-month means of +0.42 mm/day. The largest monthly increase occurred in August, where the difference was +2.70 mm/day. In December, rainfall instead recorded its largest monthly decrease, a difference of -0.32 mm/day. These monthly changes describe differences in daily averages for those months; they do not indicate that every day or month followed the same pattern.

Changes in sunshine duration

Mean daily sunshine duration had an unweighted difference across calendar-month means of -0.10 hours/day compared with the earlier period. The monthly pattern was not uniform: January recorded the largest increase, with a difference of +0.31 hours/day, while August recorded the largest decrease, at -0.52 hours/day. These figures concern average daily sunshine hours, and the overall mean summarizes calendar-month averages rather than day-weighted annual conditions.
