Overview of climate changes
Temperature changes
Averaged across calendar months, monthly mean temperature shows a difference of +0.65 °C in the more recent period; this is an unweighted comparison of monthly means, not a day-weighted annual average or a measure of daytime maximum temperatures. The largest monthly increase was in January, with a difference of +1.56 °C compared with the earlier period. In contrast, April recorded the largest monthly decrease, a difference of -0.37 °C. These extremes show that the overall mean difference does not describe every month's change.
Changes in rainfall
Mean daily rainfall, rather than monthly rainfall totals, had an unweighted mean difference across calendar months of +0.72 mm/day. This aggregate does not imply that rainfall increased in every month. The largest monthly increase was in October, where the difference was +1.38 mm/day; the largest monthly decrease came in April, with a difference of -0.39 mm/day. The opposing monthly changes put the mean difference in context without describing the amount of rainfall on any particular day.
Changes in sunshine duration
Mean daily sunshine duration had an unweighted difference across calendar-month means of -0.63 hours/day in the more recent period, not a day-weighted annual comparison. The largest monthly decrease occurred in June, with a difference of -1.49 hours/day. This monthly contrast illustrates that the aggregate does not specify the change in every month, and the measure describes mean daily hours rather than total sunshine for a month.
Changes in snowfall
Mean daily snowfall had an unweighted difference across calendar months of -0.14 mm/day; this is a comparison of monthly means, not monthly snowfall totals. The largest monthly decrease was in January, with a difference of -1.52 mm/day, while March had the largest increase, a difference of +0.30 mm/day. These contrasting monthly changes show why the mean difference should not be read as a decrease in every month.
