Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +0.91 °C compared with the earlier reference period; this is an unweighted average of monthly means, not a day-weighted annual figure or a description of every month. The largest monthly increase was in December, with a difference of +1.83 °C. These are monthly mean temperatures, not daytime maximum temperatures.

Changes in sunshine duration

Mean daily sunshine duration, averaged across calendar months, had a difference of -0.26 hours/day compared with the earlier reference period. This is an unweighted average of monthly means, not a day-weighted annual average or a change shared by every month. The largest monthly increase occurred in January, with a difference of +0.42 hours/day; the largest monthly decrease was in March, with a difference of -0.65 hours/day. The monthly contrasts show why the overall mean should not be read as a uniform month-by-month shift.

Changes in rainfall

Averaged across calendar months, mean daily rainfall shows a difference of +0.12 mm/day compared with the earlier reference period. This unweighted mean of monthly means is not a monthly total, a day-weighted annual average, or evidence that rainfall increased in every month. The largest monthly increase was in September, with a difference of +0.83 mm/day, while the largest monthly decrease was in January, with a difference of -0.60 mm/day. These figures describe mean daily amounts rather than monthly accumulation.

Averaged across calendar months, mean daily snowfall is unchanged at the displayed precision, with a difference of 0.00 mm/day compared with the earlier reference period. This rounded mean does not establish that values were identical beyond the displayed precision or that snowfall was absent. The largest monthly decrease was in February, with a difference of -0.01 mm/day. These are mean daily amounts, not monthly snowfall totals.
