Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of -0.13 °C; this is an unweighted mean of the monthly differences, not a day-weighted annual average or a measure of daytime highs. The monthly changes were not uniform: August had the largest increase, a difference of +1.26 °C, while February had the largest decrease, a difference of -1.78 °C. These extremes describe the change in the respective monthly means, rather than every day or every month.

Changes in rainfall

Mean daily rainfall, rather than monthly rainfall totals, was higher on average across calendar months: the unweighted mean difference was +0.27 mm/day. That overall average masks contrasting monthly shifts. The largest increase was in February, with a difference of +1.63 mm/day, whereas September recorded the largest decrease, a difference of -1.01 mm/day. These figures compare monthly daily averages and should not be read as changes applying to every day or as a full-year total.

Changes in sunshine duration

Mean daily sunshine duration had an unweighted difference of +0.08 hours/day when averaged across calendar months; this summarizes the monthly means, not a day-weighted annual figure. The month-to-month pattern varied: August showed the largest increase, a difference of +0.70 hours/day, while February had the largest decrease, a difference of -0.50 hours/day. These monthly comparisons describe average daily hours within each month, not the sunshine received on every individual day.
