Overview of climate changes

Temperature changes

The mean difference, averaged across calendar months, was +1.14 °C compared with the earlier reference period; this is an unweighted comparison of monthly mean temperatures, not a day-weighted annual average or a measure of daytime highs. The largest monthly increase was in October, with a difference of +1.40 °C. This identifies the strongest increase among the supplied monthly differences, rather than describing every month or a continuous change between the reference periods.

Changes in sunshine duration

Mean daily sunshine duration had an unweighted difference of -0.30 hours/day averaged across calendar months, indicating an overall decrease in the monthly means rather than a day-weighted annual change. The largest monthly decrease was in July, with a difference of -0.71 hours/day. By contrast, the largest increase was in December, at +0.05 hours/day; these are monthly differences, not evidence of a continuous trend between the periods.

Changes in rainfall

Averaged across calendar months, mean daily rainfall had a difference of 0.00 mm/day compared with the earlier reference period. This rounded mean difference is unchanged at the displayed precision; it does not imply that rainfall was unchanged in every month, and it describes daily means rather than monthly totals. The largest monthly increase in mean daily rainfall occurred in September, at +0.35 mm/day. The largest decrease was in August, at -0.22 mm/day, showing that the monthly differences moved in both directions despite the unchanged rounded mean.
