Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +1.59 °C compared with the earlier reference period; this is an unweighted comparison of monthly means, not a day-weighted annual average or a measure of daytime maximum temperatures. July had the largest monthly increase, at a difference of +2.48 °C. By contrast, November had the largest monthly decrease, with a difference of -0.05 °C. These month-specific differences show that the overall mean does not describe every month in the same way.

Changes in rainfall

Mean daily rainfall, rather than monthly totals, had an unweighted difference across calendar months of +0.07 mm/day compared with the earlier period. The monthly changes were not uniform: November recorded the largest increase, a difference of +1.04 mm/day, while March recorded the largest decrease, a difference of -0.20 mm/day. These figures describe averages of daily amounts for the respective months; they do not imply that rainfall changed in the same direction on every day.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months had a difference of -0.41 hours/day compared with the earlier reference period; this is an unweighted comparison of monthly means, not a day-weighted annual average. The largest monthly decrease occurred in April, with a difference of -0.87 hours/day. The aggregate difference describes the calendar-month averages overall, while the monthly figure identifies where the largest decrease was recorded; neither establishes a continuous change between the reference periods.
