Overview of climate changes

Temperature changes

Monthly mean temperature shows an overall difference of +0.98 °C when averaged across calendar months, comparing the more recent period with the earlier reference period; this is an unweighted mean of monthly means, not a day-weighted annual average or a measure of daytime maximum temperatures. The largest monthly increase was in September, with a difference of +1.21 °C. That identifies the strongest increase among the supplied monthly temperature differences, rather than describing every month.

Changes in rainfall

Mean daily rainfall averaged across calendar months had a difference of -0.20 mm/day in the more recent period. This is an unweighted comparison of monthly means, not a day-weighted annual average, and the figures describe daily means rather than monthly rainfall totals. The largest monthly decrease was in June, where mean daily rainfall had a difference of -3.15 mm/day. By contrast, the largest monthly increase occurred in November, with a difference of +2.60 mm/day; these contrasting month-specific changes show why the across-month mean does not describe every month.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months had a difference of -0.10 hours/day between the reference periods. This unweighted mean of monthly means summarizes the comparison across months, not a day-weighted annual average or the change in every individual month. The largest monthly decrease was in November, with a difference of -0.92 hours/day, while the largest monthly increase was in June, with a difference of +0.91 hours/day. These are the most pronounced month-specific differences in their respective directions among the supplied facts; they do not imply that sunshine changed in the same direction throughout the year.
