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 month-level means, not a day-weighted annual average or a measure of daytime highs. The month-to-month differences were not uniform: October had the largest increase, at +2.39 °C, while March had the largest decrease, at -0.21 °C. These contrasts describe the specified monthly means in the two reference periods, not a continuous change between them.

Changes in rainfall

Mean daily rainfall averaged across calendar months had a difference of -0.02 mm/day compared with the earlier reference period. This is an unweighted summary of the monthly daily means, rather than a day-weighted annual average or a monthly rainfall total, and it does not imply the same change in every month. The largest monthly increase was in March, with a difference of +0.77 mm/day; by contrast, December recorded the largest monthly decrease, at -0.91 mm/day. The monthly contrasts therefore provide a more specific picture than the small overall mean difference alone.

Changes in sunshine duration

Mean daily sunshine duration, averaged across calendar months, had a difference of -0.21 hours/day between the reference periods. This is an unweighted average of the monthly daily means, not a day-weighted annual figure, and it should not be read as an identical shift throughout the year. The largest monthly decrease was in March, at -0.69 hours/day, whereas December had the largest increase, at +0.37 hours/day. These month-specific differences qualify the overall average and do not establish a continuous trend between the periods.

Changes in snowfall

Mean daily snowfall averaged across calendar months had a difference of -0.02 mm/day compared with the earlier reference period. This unweighted summary of monthly daily means is not a day-weighted annual average or a monthly total, and a small mean difference does not mean that snowfall was absent. Month-level changes included the largest decrease in December, at -0.24 mm/day, and the largest increase in January, at +0.03 mm/day. These are differences between reference-period averages, not evidence of a continuous change between them.
