Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +1.58 °C in the more recent period. This is an unweighted mean of the monthly means, not a day-weighted annual average, and it describes the overall monthly pattern rather than a change in every individual month. The largest monthly increase was in December, with a difference of +3.67 °C compared with the earlier reference period. These are monthly mean temperatures, not daytime maximum temperatures.

Changes in rainfall

Averaged across calendar months, mean daily rainfall had a difference of +0.30 mm/day in the more recent period. This unweighted mean of monthly means does not imply the same change in each month, and the values describe daily averages rather than monthly rainfall totals. The largest monthly increase was in August, where mean daily rainfall had a difference of +2.48 mm/day compared with the earlier reference period. By contrast, the largest monthly decrease occurred in September, with a difference of -0.44 mm/day. These month-specific shifts show why the mean change should not be read as applying uniformly throughout the year.

Changes in snowfall

Averaged across calendar months, mean daily snowfall had a difference of -0.12 mm/day in the more recent period. This unweighted average summarizes monthly means and does not mean that snowfall changed by the same amount in every month; the measure is a daily average, not a monthly total. The largest monthly increase in mean daily snowfall was in February, with a difference of +1.20 mm/day. The largest monthly decrease was in April, where the difference was -1.27 mm/day compared with the earlier reference period.

Changes in sunshine duration

Mean daily sunshine duration, averaged across calendar months, had a difference of +0.01 hours/day in the more recent period. This unweighted mean summarizes the monthly means; it does not establish that sunshine increased in every month, and it is not a measure of total monthly sunshine. The largest monthly increase was in July, with a difference of +0.91 hours/day. In contrast, February had the largest monthly decrease, a difference of -0.56 hours/day compared with the earlier reference period.
