Overview of climate changes

Temperature changes

Monthly mean temperature was higher by an unweighted mean difference of +0.75 °C across calendar months in the more recent period; this summarizes the months together and does not mean that every month changed by the same amount. The largest monthly increase was in March, at +1.19 °C. These are monthly mean temperatures, not daytime maximum temperatures.

Changes in rainfall

Averaged across calendar months, mean daily rainfall had an unweighted difference of -0.88 mm/day in the more recent period, indicating a lower aggregate of monthly means rather than a uniform decrease in every month. The largest monthly decrease was in January, with a difference of -3.05 mm/day; by contrast, June had the largest increase, at +0.27 mm/day. These figures describe mean daily rainfall, not monthly totals.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months had an unweighted difference of -0.04 hours/day between the reference periods, a small decrease in the aggregate that does not describe every month individually. The largest monthly decrease occurred in February, with a difference of -0.32 hours/day, while the largest increase was in December, at +0.31 hours/day. These monthly differences sit alongside the small overall mean change.

Changes in snowfall

Across calendar months, mean daily snowfall had an unweighted difference of -0.03 mm/day in the more recent period. This is an aggregate of monthly means and does not imply the same change in every month. The largest monthly decrease was in February, at a difference of -0.18 mm/day. The measure is mean daily snowfall, not a monthly total.
