Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperatures show a difference of +0.95 °C in the more recent period. This is an unweighted comparison of monthly means, not a day-weighted annual average, and it describes the overall average rather than every month. The clearest monthly contrast is in March, with a difference of +2.22 °C; the largest monthly decrease was in July, at -0.44 °C. These are changes in monthly mean temperature, not daytime maximum temperatures, and neither monthly result implies that other months followed the same pattern.

Changes in rainfall

Mean daily rainfall, averaged across calendar months, shows a difference of -0.15 mm/day between the reference periods. This unweighted mean of monthly averages summarizes the broad comparison; it is not a day-weighted annual average or a monthly rainfall total, and it does not describe every month individually. The largest monthly decrease was in August, where mean daily rainfall had a difference of -0.64 mm/day. In contrast, September recorded the largest monthly increase, a difference of +0.09 mm/day. These month-specific daily averages show that individual months could differ from the overall mean comparison.

Changes in sunshine duration

Mean daily sunshine duration, averaged across calendar months, had a difference of -0.37 hours/day in the more recent period. This is an unweighted average of the calendar-month means, not a day-weighted annual figure, so it should be read as an overall comparison rather than a description of every month. The largest monthly decrease occurred in July, with a difference of -0.90 hours/day hours per day. The largest increase was much more limited in scope: in December, the difference was +0.06 hours/day. These monthly comparisons concern average daily sunshine, not total sunshine accumulated over a month.

Changes in snowfall

Averaged across calendar months, mean daily snowfall had a difference of +0.16 mm/day between the periods. This unweighted mean summarizes monthly daily averages and is not a day-weighted annual average or a monthly snowfall total. The largest monthly increase was in May, with a difference of +0.59 mm/day in mean daily snowfall; the largest decrease was in June, at -0.22 mm/day. These differences describe the specified months and do not establish the direction of change in every month.
