Overview of climate changes

Temperature changes

Monthly mean temperatures were higher by an average difference of +1.46 °C across calendar months in the more recent period; this unweighted average describes the monthly means, not daytime maximum temperatures or the change in every month. The largest monthly increase was in March, with a difference of +3.03 °C compared with the earlier reference period. The largest monthly decrease was in October, with a difference of -0.10 °C. These monthly extremes show that the comparison was not uniform across the calendar.

Changes in snowfall

Mean daily snowfall averaged across calendar months was lower by a difference of -0.03 mm/day in the more recent period. This small mean difference summarizes monthly averages and does not indicate that snowfall was absent. The largest monthly increase occurred in February, with a difference of +0.88 mm/day; the largest monthly decrease was in March, with a difference of -1.06 mm/day. These monthly changes concern mean daily amounts, not snowfall totals for the months.

Changes in rainfall

Mean daily rainfall averaged across calendar months was lower by a difference of -0.25 mm/day in the more recent period. This is an unweighted comparison of monthly means, not a day-weighted annual average or a monthly rainfall total. The largest monthly increase occurred in June, with a difference of +0.32 mm/day; the largest monthly decrease was in July, with a difference of -1.00 mm/day. The opposing monthly changes help qualify the lower average, and describe mean daily amounts rather than totals for those months.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months was lower by a difference of -0.06 hours/day in the more recent period. This unweighted mean difference summarizes the monthly averages and does not imply that every month had less sunshine. The largest monthly increase was in March, with a difference of +0.39 hours/day, while the largest monthly decrease was in February, with a difference of -0.39 hours/day. These are differences in mean daily hours for the named months.
