Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +1.36 °C compared with the earlier reference period; this is an unweighted mean of the calendar-month means, not a day-weighted annual average or a measure of daytime maximum temperatures. The largest monthly increase was in December, with a difference of +1.64 °C. These figures describe the period-level averages and the identified monthly change, rather than a continuous trend or a change shared by every month.

Changes in rainfall

Mean daily rainfall, rather than monthly rainfall totals, had an unweighted mean difference of +0.99 mm/day averaged across calendar months. The month-to-month pattern was not uniform: in January, mean daily rainfall had the largest monthly increase, a difference of +3.82 mm/day, while September had the largest monthly decrease, a difference of -1.23 mm/day. The overall mean describes the aggregate of calendar-month means; it does not imply that rainfall increased in every month or on every day.

Changes in sunshine duration

Mean daily sunshine duration had an unweighted mean difference of -0.59 hours/day averaged across calendar months, not a day-weighted annual average. The largest monthly decrease occurred in January, with a difference of -1.28 hours/day. This period comparison describes averaged daily sunshine hours; it does not establish a continuous change or mean that every month had less sunshine.
