Overview of climate changes

Temperature changes

Across calendar months, the unweighted mean difference in monthly mean temperature was an increase of +0.81 °C; this summarizes monthly averages rather than a day-weighted annual average, and it does not mean that every month's temperature rose by the same amount. These are monthly mean conditions, not daytime maximum temperatures. The largest monthly increase in mean temperature was in February, with a difference of +1.66 °C. This identifies the strongest monthly increase in the supplied comparison, not a continuous change between the reference periods.

Changes in rainfall

The unweighted mean difference in mean daily rainfall, averaged across calendar months, was an increase of +0.65 mm/day. This describes the aggregate of monthly averages, not a day-weighted annual amount or a change shared by every month; rainfall figures here are daily means rather than monthly totals. The largest monthly increase in mean daily rainfall occurred in November, with a difference of +1.69 mm/day. It marks the strongest monthly increase in this comparison and should not be read as a monthly rainfall total.

Changes in sunshine duration

Averaged across calendar months, the unweighted mean difference in mean daily sunshine duration was a decrease of -0.26 hours/day. This aggregate does not imply that sunshine decreased by that amount in each month, and it is not a day-weighted annual average. The largest monthly decrease in mean daily sunshine duration was in November, with a difference of -0.61 hours/day. This is the strongest monthly decrease identified in the supplied data, not evidence of a continuous decline between the reference periods.
