Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +2.83 °C in the more recent period. This is an unweighted mean of the monthly means, not a day-weighted annual average, and it does not imply that every month changed by the same amount. The largest monthly increase was in December, with a difference of +5.59 °C compared with the earlier reference period. This refers to monthly mean temperature, not daytime maximum temperature.

Changes in snowfall

Averaged across calendar months, mean daily snowfall decreased by -0.36 mm/day in the more recent period. This is an unweighted average of monthly means, not a day-weighted annual average, and it does not indicate that snowfall decreased in every month. Monthly differences varied in direction: January recorded the largest increase, with a difference of +4.61 mm/day, while February recorded the largest decrease, with a difference of -2.90 mm/day. These figures describe mean daily snowfall, not monthly totals.

Changes in rainfall

Averaged across calendar months, mean daily rainfall increased by +0.21 mm/day in the more recent period. This is an unweighted average of monthly means, not a day-weighted annual average; it describes the overall comparison and does not mean rainfall increased in every month. The largest monthly increase was in October, where mean daily rainfall had a difference of +1.35 mm/day. In contrast, June had the largest monthly decrease, with a difference of -1.12 mm/day. These are daily mean amounts, not monthly rainfall totals.

Changes in sunshine duration

Averaged across calendar months, mean daily sunshine duration decreased by -0.16 hours/day in the more recent period. The unweighted mean summarizes monthly averages, rather than a day-weighted annual total, and does not describe every month individually. The largest monthly decrease was in May, with a difference of -1.03 hours/day. The largest monthly increase, by comparison, was in June, with a difference of +0.59 hours/day; both refer to mean daily sunshine hours.
