Overview of climate changes

Temperature changes

Averaged across calendar months, the monthly mean temperature difference was +1.07 °C in the more recent period compared with the earlier reference period. This is an unweighted average of monthly means, not a day-weighted annual average, and monthly mean temperature does not represent daytime maximum temperatures. The largest monthly increase was in July, with a difference of +1.45 °C; that identifies the strongest increase among the supplied monthly comparisons, not a change shared by every month.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months had a difference of -0.31 hours/day compared with the earlier reference period. This is an unweighted average of the calendar-month means, rather than a day-weighted annual figure. Monthly differences varied: July had the largest decrease, with a difference of -0.71 hours/day, whereas December had the largest increase, at +0.11 hours/day. Those monthly contrasts qualify the aggregate mean; they do not imply the same change in each month.

Changes in rainfall

Mean daily rainfall averaged across calendar months had a difference of -0.08 mm/day compared with the earlier reference period. This unweighted mean of monthly differences is not a day-weighted annual average, and the figures describe daily mean amounts rather than monthly rainfall totals. The largest monthly increase was in January, at +0.48 mm/day, while the largest monthly decrease was in December, at -0.65 mm/day. These contrasting monthly differences show why the overall mean should not be read as a description of every month.
