Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +2.37 °C compared with the earlier reference period. This is an unweighted comparison of the monthly means, not a day-weighted annual average, and it does not mean that every month warmed by the same amount. The largest monthly increase in mean temperature was in January, with a difference of +4.76 °C. These are monthly mean temperatures, not daytime maximum temperatures.

Changes in snowfall

Averaged across calendar months, mean daily snowfall shows a difference of +0.67 mm/day compared with the earlier reference period. This unweighted mean summarizes the monthly averages, not annual snowfall totals, and does not indicate that the same difference occurred in every month. The largest monthly increase in mean daily snowfall occurred in January, with a difference of +3.65 mm/day. In contrast, October recorded the largest monthly decrease, a difference of -0.72 mm/day; both are daily mean amounts, not monthly totals.

Changes in rainfall

Averaged across calendar months, mean daily rainfall has a difference of +0.17 mm/day compared with the earlier reference period. This unweighted mean describes the aggregate of monthly averages; it is not a day-weighted annual figure or a monthly rainfall total. The monthly changes were not uniform: September had the largest increase, a difference of +0.81 mm/day, while August had the largest decrease, a difference of -0.56 mm/day. These figures describe mean daily rainfall in those months, rather than rainfall totals.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months shows a difference of -0.11 hours/day in the more recent period. This is an unweighted mean of the calendar-month averages, not a day-weighted annual average, and it does not imply an identical change in each month. The largest monthly decrease was in January, with a difference of -0.84 hours/day; the largest increase was in August, at +0.63 hours/day. These values describe differences in average daily sunshine hours for the named months.
