Overview of climate changes

Temperature changes

Monthly mean temperature was higher overall in the more recent period: averaged across calendar months, the difference was +2.81 °C. This unweighted mean summarizes the month-by-month averages; it is not a day-weighted annual average and does not mean that every month warmed by the same amount. The largest monthly increase was in January, with a difference of +6.47 °C compared with the earlier reference period. These are monthly means, not daytime maximum temperatures.

Changes in snowfall

Averaged across calendar months, mean daily snowfall was higher in the more recent period by a difference of +0.07 mm/day. This is an unweighted mean of monthly averages, not a day-weighted annual figure, and it does not describe the direction of change in every month. The largest monthly increase in mean daily snowfall was in January, with a difference of +3.27 mm/day. The largest decrease was in February, at -2.62 mm/day; both describe daily means rather than monthly snowfall totals.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months was slightly lower in the more recent period, with a difference of -0.08 hours/day. This unweighted summary of monthly means does not indicate that sunshine decreased in every month. The monthly differences were not uniform: May had the largest increase, at +0.52 hours/day, while January had the largest decrease, at -0.90 hours/day. These figures describe mean daily sunshine hours, not total sunshine over each month.

Changes in rainfall

Mean daily rainfall was higher overall in the more recent period, with an unweighted difference of +0.22 mm/day averaged across calendar months. This summarizes the monthly means rather than a day-weighted annual average, and it does not imply an increase in every month. The largest monthly increase was in September, a difference of +0.76 mm/day in mean daily rainfall. By contrast, August had the largest monthly decrease, with a difference of -0.40 mm/day. These are daily mean amounts, not monthly rainfall totals.
