Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +1.01 °C compared with the earlier reference period; this is an unweighted mean of monthly averages, not a day-weighted annual figure or a measure of daytime highs. The largest monthly increase was in January, with a difference of +2.59 °C; by contrast, the largest decrease was in August, at -0.07 °C. These monthly comparisons show that the overall mean difference does not describe every month.

Changes in rainfall

Mean daily rainfall also had a positive difference averaged across calendar months: +0.59 mm/day. This describes average daily amounts across the calendar-month means, not monthly rainfall totals or the number of rainy days. The largest rainfall increase occurred in August, at +2.10 mm/day, while April had the largest decrease, -0.10 mm/day. The month-specific differences therefore vary and should not be read as a uniform change in rainfall through the year.

Changes in sunshine duration

Sunshine duration had a mean difference across calendar months of -0.17 hours/day per day. The largest increase was in July, at +0.62 hours/day, while the largest decrease was in August, at -0.60 hours/day; these are daily averages, not a guarantee of sunshine on any particular day.
