Overview of climate changes

Changes in snowfall

Averaged across calendar months, mean daily snowfall had a difference of -0.62 mm/day in the more recent period. This is an unweighted comparison of monthly means, not an annual total, and does not imply the same change in each month. The largest monthly decrease was in March, with a difference of -4.28 mm/day; by contrast, October had the largest increase, +0.31 mm/day. These month-specific differences describe mean daily snowfall, not monthly snowfall totals.

Temperature changes

Averaged across calendar months, monthly mean temperature was higher by +1.51 °C in the more recent reference period; this is a difference between period averages, not evidence of a continuous trend, and it describes monthly means rather than daytime highs. The largest monthly increase was in March, at +2.94 °C, while October had the largest decrease, -0.77 °C. These mark the strongest month-specific differences, not a uniform change across the year.

Changes in rainfall

Averaged across calendar months, mean daily rainfall had a difference of -0.01 mm/day in the more recent period, a near-level overall comparison rather than a claim that every month was similar. The figure describes an unweighted average of monthly means, not a day-weighted annual amount or a monthly total. The largest monthly increase was in May, with a difference of +0.58 mm/day; the largest decrease was in April, at -0.89 mm/day. The contrasting month-specific differences show why the near-level average should not be read as an unchanged pattern in every month.

Changes in sunshine duration

Mean daily sunshine duration, averaged across calendar months, was higher by +0.15 hours/day in the more recent period. This summarizes the monthly means across the calendar and does not imply that sunshine increased in every month. June recorded the largest monthly increase, +1.86 hours/day, whereas the largest decrease was in October, at -0.31 hours/day. These are differences in mean daily hours for the named months, rather than totals over each month.
