Overview of climate changes

Temperature changes

Monthly mean temperature averaged across calendar months shows a difference of +1.36 °C compared with the earlier reference period. This is an unweighted mean of the calendar-month means, not a day-weighted annual average, and it does not describe daytime maximum temperatures or imply that every month changed by the same amount. The largest monthly increase was in December, with a difference of +1.80 °C. That identifies the strongest monthly increase in the supplied comparison, rather than a continuous trend between the reference periods.

Changes in rainfall

Mean daily rainfall averaged across calendar months had a difference of -0.09 mm/day compared with the earlier reference period. This is an unweighted average of monthly means, not a day-weighted annual figure; it summarizes the overall monthly pattern and does not mean that daily rainfall was lower on every day. The monthly differences varied in direction: January had the largest increase, a difference of +0.19 mm/day, while December had the largest decrease, a difference of -0.67 mm/day. These are changes in mean daily rainfall, not monthly rainfall totals, and they describe the named months rather than every day within them.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months had a difference of -0.28 hours/day compared with the earlier reference period. The figure is an unweighted average of monthly means, not a day-weighted annual average, and does not establish the same change in each month. Monthly differences were not uniform: July recorded the largest decrease, a difference of -0.66 hours/day, whereas December had the largest increase, a difference of +0.11 hours/day. These are differences in mean daily hours for the specified months, not measures of total monthly sunshine.
