Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +0.76 °C in the more recent reference period. This is an unweighted comparison of monthly means, not a day-weighted annual average or a measure of daytime highs. The largest monthly increase was in February, with a difference of +1.76 °C. By contrast, June had the largest decrease, a difference of -0.18 °C; these extrema indicate that monthly changes were not uniform.

Changes in rainfall

Mean daily rainfall, averaged across calendar months, had a difference of -0.30 mm/day. This aggregate comparison concerns daily means rather than monthly rainfall totals, and it does not imply that every month was drier. The largest monthly decrease was in July, at a difference of -1.21 mm/day, while November recorded the largest increase, a difference of +0.32 mm/day. These contrasts describe average daily amounts, not how often rain fell or what conditions any particular day brought.

Changes in sunshine duration

Mean daily sunshine duration had an across-month difference of -0.31 hours/day. The largest monthly decrease was in November, with a difference of -0.78 hours/day, while the largest increase came in September, at +0.48 hours/day; monthly averages do not guarantee the sunshine on a given day.
