Overview of climate changes

Temperature changes

Monthly mean temperatures were higher in the more recent period, with a difference of +1.05 °C averaged across calendar months. This unweighted average of monthly means describes the overall comparison, not a change in every month, and these figures are not daytime maximum temperatures. The largest monthly increase was in March, at +1.38 °C; that identifies the strongest increase among the monthly comparisons, rather than a continuous trend between the reference periods.

Changes in rainfall

Mean daily rainfall was lower overall in the more recent period, with a difference of -0.49 mm/day averaged across calendar months. This unweighted comparison of monthly means does not mean rainfall decreased in every month, and the figures describe daily averages rather than monthly totals. The largest monthly decrease was in June, with a difference of -1.73 mm/day. In contrast, November had the largest increase, at +2.07 mm/day, showing that the direction of the monthly differences varied.

Changes in sunshine duration

Mean daily sunshine duration showed a small overall decrease in the more recent period: the difference was -0.06 hours/day averaged across calendar months. This unweighted average of monthly means is not a claim that sunshine declined in every month. The largest monthly decrease occurred in November, at -0.89 hours/day, while the largest increase was in December, at +0.50 hours/day. These month-specific differences show that the overall average masks variation in direction; they describe differences between reference periods, not a continuous change over time.
