Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +0.72 °C compared with the earlier reference period; this is an unweighted average of monthly means, not a day-weighted annual average or a measure of daytime maximum temperatures. The largest monthly increase was in July, with a difference of +1.95 °C. By contrast, September had the largest monthly decrease, a difference of -0.18 °C; these month-specific comparisons do not imply that every month followed the overall mean difference.

Changes in rainfall

Mean daily rainfall, rather than monthly rainfall totals, had an unweighted mean difference across calendar months of +0.78 mm/day in the more recent period. The largest monthly increase was in November, at a difference of +1.87 mm/day, while the largest monthly decrease occurred in October, at a difference of -1.39 mm/day. These daily-mean differences describe particular months and do not establish the same change in every month.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months had a difference of -0.34 hours/day compared with the earlier reference period; this is an unweighted average of the monthly means, not a day-weighted annual figure. The month-specific differences varied: January recorded the largest increase, at +0.23 hours/day, whereas May recorded the largest decrease, at -1.01 hours/day. These extrema describe monthly mean daily sunshine, not every day within those months.

Changes in snowfall

Mean daily snowfall, not monthly totals, had an unweighted mean difference across calendar months of -0.12 mm/day in the more recent period. The largest monthly decrease was in January, with a difference of -0.71 mm/day; the largest increase occurred in March, at +0.27 mm/day. These monthly daily-mean differences indicate variation between the reference periods and do not describe every day or imply that snowfall was absent in either period.
