Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +1.45 °C compared with the earlier reference period. This is an unweighted mean of the monthly means, not a day-weighted annual average, and it describes the overall difference between the two periods rather than a continuous trend. The largest monthly increase was in January, with a difference of +2.07 °C. These are monthly mean temperatures, not daytime maximum temperatures.

Changes in rainfall

Averaged across calendar months, mean daily rainfall shows a difference of -0.44 mm/day compared with the earlier reference period. This unweighted mean across calendar-month means is not a day-weighted annual average, and it does not mean every month was drier. The monthly contrasts show that clearly: in April, the largest decrease was a difference of -1.93 mm/day, while in July, the largest increase was a difference of +1.77 mm/day. These figures are mean daily amounts, not monthly rainfall totals.

Changes in sunshine duration

Averaged across calendar months, mean daily sunshine duration shows a difference of -0.47 hours/day compared with the earlier reference period. This is an unweighted mean across calendar-month means, not a day-weighted annual average, and the period-level difference should not be read as a change in every month. The largest monthly decrease occurred in July, with a difference of -2.03 hours/day; by contrast, April had the largest monthly increase, a difference of +0.09 hours/day. The figures describe mean daily hours of sunshine, rather than total sunshine accumulated over a month.
