Overview of climate changes

Changes in rainfall

Averaged across calendar months, mean daily rainfall shows a difference of -0.38 mm/day in the more recent period; this unweighted average of monthly means is not a day-weighted annual average, and it does not imply that rainfall decreased in every month. The largest monthly decrease was in February, with a difference of -2.03 mm/day, while May had the largest monthly increase, a difference of +0.62 mm/day. These are changes in mean daily amounts, not monthly rainfall totals.

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +0.50 °C compared with the earlier reference period; this is an unweighted mean of the calendar-month means, not a day-weighted annual average, and it does not mean every month changed by the same amount. The largest monthly increase was in February, with a difference of +0.70 °C. These figures describe monthly means rather than daytime maximum temperatures.

Changes in sunshine duration

Averaged across calendar months, mean daily sunshine duration shows a difference of -0.15 hours/day compared with the earlier reference period. This is an unweighted average of monthly means, not a day-weighted annual average, and it does not indicate the same change in every month. The largest monthly decrease was in September, with a difference of -0.46 hours/day; in March, the largest monthly increase was a difference of +0.09 hours/day. The figures refer to mean daily sunshine hours.
