Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +0.47 °C compared with the earlier reference period; this is an unweighted mean of the monthly means, not a day-weighted annual average or a measure of daytime maximum temperatures. The largest monthly increase was in August, with a difference of +0.73 °C. That identifies the strongest reported monthly increase, rather than implying the same change in every month.

Changes in rainfall

Averaged across calendar months, mean daily rainfall increased by a difference of +0.96 mm/day in the more recent period. This unweighted mean describes the monthly daily-mean values, not a day-weighted annual average or a monthly rainfall total. The largest monthly increase was in July, at a difference of +2.65 mm/day in mean daily rainfall. In contrast, February had the largest monthly decrease, with a difference of -0.20 mm/day; these extrema show that the direction was not identical across all months.

Changes in sunshine duration

Averaged across calendar months, mean daily sunshine duration had a difference of -0.22 hours/day compared with the earlier period. This is an unweighted mean across monthly averages, not a day-weighted annual measure. The monthly differences varied in direction: February had the largest increase, with a difference of +0.13 hours/day, while July had the largest decrease, with a difference of -0.61 hours/day. These are changes in mean daily sunshine hours for the specified months, not descriptions of every day.
