Overview of climate changes

Temperature changes

Averaged across calendar months, the difference in monthly mean temperature was -0.97 °C; this is an unweighted comparison of monthly means, not a day-weighted annual average or a measure of daytime maximum temperatures. The largest monthly decrease was in May, at -3.66 °C, while August had the largest monthly increase, at +1.08 °C. These month-specific differences show that the overall mean does not describe every month in the same way.

Changes in rainfall

Mean daily rainfall averaged across calendar months had a difference of -0.10 mm/day, an unweighted comparison of monthly means rather than a change in annual or monthly totals. The largest monthly decrease occurred in August, with a difference of -2.55 mm/day; by contrast, the largest monthly increase was in May, at +0.83 mm/day. These are differences in daily averages within the named months, not descriptions of every rainy day.

Changes in sunshine duration

Mean daily sunshine duration, averaged across calendar months, had a difference of -0.13 hours/day; the mean is unweighted across monthly means rather than day-weighted across the year. The largest monthly increase was in August, at +1.14 hours/day, whereas the largest decrease was in May, at -0.98 hours/day. These monthly averages summarize sunshine duration and do not imply the same difference on each day.
