Overview of climate changes

Changes in snowfall

Mean daily snowfall, averaged across calendar months, has a difference of -1.17 mm/day. This unweighted mean compares monthly means rather than monthly totals or a day-weighted annual average; the comparison concerns recorded snowfall and does not mean snowfall was absent in either period. The largest monthly decrease in mean daily snowfall was in January, with a difference of -5.09 mm/day. In contrast, the largest monthly increase occurred in November, at +0.28 mm/day; both figures are daily means, not accumulated monthly amounts.

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of -0.41 °C; this unweighted mean summarizes monthly means rather than a day-weighted annual average, and it does not imply that every month changed in the same way. The largest monthly increase was in December, with a difference of +1.43 °C, while the largest monthly decrease was in October, at -2.15 °C. These are changes in monthly mean temperature, not daytime maximum temperatures.

Changes in sunshine duration

Averaged across calendar months, mean daily sunshine duration shows a difference of -0.26 hours/day. The figure is an unweighted mean of monthly means, so it describes the overall comparison without implying the same change in every month. The largest monthly increase in mean daily sunshine was in January, at +0.31 hours/day, while the largest decrease was in October, at -0.68 hours/day. These are differences in daily hours averaged for each month, not measures of total sunshine accumulated across a month.

Changes in rainfall

Mean daily rainfall, averaged across calendar months, has a difference of -0.04 mm/day. This is an unweighted comparison of monthly means, not a change in monthly rainfall totals or a day-weighted annual average. The largest monthly increase in mean daily rainfall occurred in October, with a difference of +0.63 mm/day; the largest monthly decrease was in April, with a difference of -0.63 mm/day. These daily mean differences describe the specified months, not totals accumulated over them.
