Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +1.20 °C in the more recent period; this unweighted comparison summarizes monthly means, not daytime maximum temperatures. The strongest monthly increase was in October, with a difference of +2.47 °C. In contrast, March had the largest monthly decrease, a difference of -0.13 °C. These extrema describe the largest increase and decrease respectively, rather than changes shared by every month.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months had a difference of -0.31 hours/day in the more recent period. This is an unweighted summary of monthly means, not a day-weighted annual average. The largest monthly decrease occurred in March, at a difference of -0.83 hours/day; by contrast, December had the largest increase, a difference of +0.25 hours/day. These monthly extremes show that the mean difference does not describe every month individually.

Changes in rainfall

The unweighted mean difference in mean daily rainfall, averaged across calendar months, was -0.03 mm/day; these are daily means, not monthly rainfall totals. Monthly changes varied: March recorded the largest increase, a difference of +0.73 mm/day, while December recorded the largest decrease, a difference of -0.98 mm/day. The mean summarizes the monthly averages and does not imply that rainfall changed in the same direction in every month.

Changes in snowfall

Mean daily snowfall also shows a difference averaged across calendar months of -0.02 mm/day. This unweighted mean compares monthly averages, not monthly totals, and its rounded value should not be taken to mean snowfall was absent or unchanged at finer precision. The largest monthly decrease was in December, with a difference of -0.24 mm/day, while March had the largest increase, a difference of +0.02 mm/day. These month-specific differences need not represent the pattern in every month.
