Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +0.81 °C between the reference periods; this is an unweighted mean of monthly averages, not a day-weighted annual figure or a measure of daytime highs. The largest monthly increase was in July, with a difference of +1.26 °C. That identifies the strongest increase among the monthly means, rather than describing every month.

Changes in sunshine duration

Mean daily sunshine duration, averaged across calendar months, had a difference of -0.72 hours/day between the reference periods. This unweighted summary of monthly means is not a day-weighted annual average. The clearest monthly decrease was in December, with a difference of -1.49 hours/day; the largest increase was much smaller, in June, at +0.02 hours/day. The monthly extremes therefore provide context for the average decrease without implying that every month followed the same pattern.

Changes in rainfall

Mean daily rainfall averaged across calendar months had a difference of +1.16 mm/day between periods. This unweighted average of monthly means describes a broad shift in the daily averages, not a change in monthly rainfall totals or a uniform increase in each month. The largest monthly increase occurred in May, with a difference of +2.78 mm/day; by contrast, November had the largest decrease, a difference of -0.59 mm/day. These contrasting monthly results show why the overall mean should not be read as a description of every month's rainfall.

Changes in snowfall

Mean daily snowfall averaged across calendar months had an unchanged difference of 0.00 mm/day at the displayed precision. This rounded equality does not establish that snowfall was absent or that there was no difference at finer precision. The largest monthly increase was in January, with a difference of +0.01 mm/day; it describes a monthly mean daily amount, not a monthly total.
