Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +0.31 °C in the more recent period. This is a comparison of the unweighted monthly means, not a day-weighted annual average, and it describes the aggregate rather than a change shared by every month. The largest monthly increase was in July, with a difference of +0.71 °C compared with the earlier reference period. By contrast, November had the largest monthly decrease, a difference of -0.41 °C; these are the two monthly extremes, not a description of every month.

Changes in rainfall

Mean daily rainfall, rather than monthly totals, was higher on average across calendar months, with a difference of +1.85 mm/day compared with the earlier reference period. This unweighted comparison summarizes the monthly means and does not imply that rainfall increased in every month. April recorded the largest monthly increase in mean daily rainfall, with a difference of +4.25 mm/day. This identifies the strongest monthly increase in the supplied comparison, not the change in a month’s total rainfall.

Changes in sunshine duration

Mean daily sunshine duration decreased on average across calendar months, with a difference of -0.52 hours/day in the more recent period. This is an unweighted average of monthly means, not a day-weighted annual measure, and does not mean that sunshine duration fell in every month. The largest monthly decrease in mean daily sunshine duration occurred in February, with a difference of -1.39 hours/day compared with the earlier reference period. This marks the strongest monthly decrease in the supplied facts rather than a uniform change throughout the year.
