Overview of climate changes

Temperature changes

Monthly mean temperatures were higher on average across calendar months in the more recent period, with a mean difference of +1.14 °C; this is an unweighted average of the calendar-month means, not a day-weighted annual average or a measure of daytime maximum temperatures. The largest monthly increase was in November, where the difference was +1.77 °C. This identifies the strongest increase among the monthly means, rather than describing every month's change.

Changes in rainfall

Averaged across calendar months, mean daily rainfall had a difference of -0.41 mm/day in the more recent period. This unweighted mean of monthly means describes daily rainfall rates, not monthly rainfall totals, and does not imply the same change in every month. The largest monthly decrease was in August, with a difference of -2.38 mm/day in mean daily rainfall. By contrast, the largest monthly increases occurred in January / February, each with a difference of +0.62 mm/day; these month-specific differences show that the pattern was not uniform.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months had a difference of +0.08 hours/day in the more recent period. This is an unweighted mean of monthly means, not a day-weighted annual figure, and it does not mean that sunshine increased in every month. The largest monthly increase was in June, with a difference of +0.94 hours/day in mean daily sunshine. In January, the largest monthly decrease was -0.37 hours/day, illustrating contrasting month-level differences rather than a uniform shift.
