Overview of climate changes

Temperature changes

Across calendar months, the unweighted mean difference in monthly mean temperature was +0.39 °C compared with the earlier reference period; this summarizes the months collectively and does not imply the same change in every month. The largest monthly increase was in March, with a difference of +1.30 °C. The largest monthly decrease was in May, at a difference of -0.68 °C. These values describe monthly mean temperatures, not daytime maximum temperatures.

Changes in rainfall

Mean daily rainfall averaged across calendar months showed an unweighted difference of +0.27 mm/day in the more recent period. This is an aggregate of monthly means, not a day-weighted annual average or a monthly rainfall total, and it does not describe every month individually. The largest monthly increase was in September, with a difference of +1.58 mm/day. By contrast, the largest monthly decrease occurred in January, at a difference of -0.26 mm/day; these month-specific changes show that the average difference did not apply uniformly through the calendar.

Changes in sunshine duration

Mean daily sunshine duration, averaged without weighting across calendar months, had a difference of -0.13 hours/day compared with the earlier reference period. This mean summarizes the monthly averages rather than indicating that sunshine changed by the same amount in each month. The largest monthly increase was in January, at a difference of +0.21 hours/day, while the largest decrease was in August, at a difference of -0.66 hours/day. These are differences in mean daily hours for the respective months, not measures of total sunshine over a month.
