Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of -0.16 °C compared with the earlier reference period; this unweighted comparison describes the monthly means, not a day-weighted annual average or daytime highs. The largest monthly decrease was in January, with a difference of -1.54 °C, while the largest increase was in August, at +1.24 °C. These contrasting monthly shifts show why the overall mean should not be read as a change applying equally to every month.

Changes in rainfall

Mean daily rainfall averaged across calendar months had a difference of +1.35 mm/day, an increase in the more recent period; these are daily means rather than monthly rainfall totals. The largest monthly increase occurred in March, at +3.75 mm/day, while August had the largest decrease, with a difference of -1.16 mm/day. Such changes describe average amounts, not how many rainy days occurred or the conditions on any particular date.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months changed by -0.10 hours/day. Monthly differences varied: November saw the largest decrease, with a difference of -1.56 hours/day, whereas August recorded the largest increase, at +0.81 hours/day. These averages indicate a change in typical daily sunshine duration, not guaranteed sunshine on individual days.
