Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +1.12 °C compared with the earlier reference period; this is an unweighted mean of monthly means, not a day-weighted annual average or a measure of daytime highs. The largest monthly increase was in June, with a difference of +1.59 °C. These figures describe a comparison between reference-period averages, not a continuous change through time or a pattern shared by every month.

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 average of monthly means, rather than a day-weighted annual figure, and it does not imply the same change in every month. The largest monthly increase occurred in January, with a difference of +0.43 mm/day, while the largest monthly decrease was in December, with a difference of -0.40 mm/day. These are changes in daily averages, not monthly rainfall totals; the contrasting month-specific differences show why the overall mean should not be read as a uniform monthly pattern.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months had a difference of -0.37 hours/day compared with the earlier reference period. This is an unweighted mean of monthly averages, not a day-weighted annual measure, and does not describe every month's change. The largest monthly decrease was in April, with a difference of -0.87 hours/day. Together, these figures describe differences between the two periods' averages; they do not establish a continuous trend between them.
