Overview of climate changes

Temperature changes

The monthly mean temperature difference, averaged across calendar months, was an increase of +2.18 °C compared with the earlier reference period; this summarizes monthly means rather than daytime maximum temperatures or a change in every month. The largest monthly increase was in September, with a difference of +2.92 °C. This identifies the strongest reported monthly increase, not a continuous change between the reference periods.

Changes in sunshine duration

Mean daily sunshine duration, averaged across calendar months, showed a difference of -0.10 hours/day in the more recent period. This summarizes monthly mean daily hours and does not establish a uniform change across individual days or months. The largest monthly decrease was in March, with a difference of -0.22 hours/day; the largest monthly increase was in December, with a difference of +0.07 hours/day. These contrasting monthly results show why the across-month mean should not be read as describing every month.

Changes in rainfall

Mean daily rainfall, averaged across calendar months, had a difference of -0.02 mm/day compared with the earlier period. This is an average of monthly means, not a day-weighted annual figure or a monthly rainfall total. The largest monthly decrease was in October, with a difference of -0.09 mm/day; by contrast, the largest monthly increase was in February, with a difference of +0.02 mm/day. These pinpoint the strongest reported changes in opposite directions, without implying that every month followed either pattern.
