Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature was higher by +0.43 °C in the more recent reference period. This describes the difference between the periods’ monthly means, not a continuous trend or a change in every month, and these means are not daytime maximum temperatures. The largest monthly temperature increase was in February, with a difference of +1.42 °C. By contrast, January had the largest decrease, at -0.44 °C; these two monthly differences show why the overall average does not describe every calendar month.

Changes in rainfall

Mean daily rainfall was higher by +0.72 mm/day averaged across calendar months. This is a comparison of monthly mean daily amounts, not monthly rainfall totals, and it does not establish that every month became wetter. The largest monthly increase was in June, at +1.77 mm/day, while March had the largest decrease, at -0.63 mm/day. These differences describe mean daily amounts for those months, not how many rainy days occurred.

Changes in sunshine duration

Mean daily sunshine duration changed by -0.03 hours/day on average across calendar months, a modest aggregate difference that should not be read as the change in every month. The largest monthly increase was in March, at +0.82 hours/day, while the largest decrease was in June, at -0.53 hours/day.
