Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +1.68 °C compared with the earlier reference period; this is an unweighted comparison of monthly means, not a day-weighted annual average or a measure of daytime highs. The largest monthly increase was in January, with a difference of +4.47 °C. That marks the most pronounced increase among the supplied monthly temperature differences, rather than implying that every month warmed by the same amount.

Changes in snowfall

Mean daily snowfall averaged across calendar months had a difference of -0.47 mm/day. This aggregate decrease does not mean every month saw less snowfall: February had the largest monthly decrease, a difference of -2.34 mm/day, while January recorded the largest increase, a difference of +0.99 mm/day. These figures describe mean daily amounts, not monthly snowfall totals, and the mean across calendar months is unweighted.

Changes in rainfall

Mean daily rainfall, rather than monthly totals, was higher on average across calendar months, with a difference of +0.38 mm/day. The monthly pattern was not uniform: August had the largest increase, a difference of +0.91 mm/day, while April recorded the largest decrease, a difference of -0.31 mm/day. These are changes in monthly mean daily amounts, so they do not describe every day's rainfall or establish the direction of change in each month.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months shows a difference of -0.30 hours/day compared with the earlier period. Month-to-month differences varied: the largest decrease was in January, at -1.20 hours/day, whereas July had the largest increase, at +0.23 hours/day. The overall mean summarizes the monthly averages without weighting them by the number of days in each month; it does not mean sunshine fell in every month.
