Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +0.62 °C compared with the earlier reference period; this unweighted mean summarizes monthly means rather than a day-weighted annual average or daytime maximum temperatures. The largest monthly increase was in December, with a difference of +0.74 °C. This identifies the strongest increase among the reported monthly changes, not a uniform change in every month.

Changes in rainfall

Averaged across calendar months, mean daily rainfall shows a difference of +0.70 mm/day compared with the earlier reference period. This is an unweighted average of monthly means, not a day-weighted annual average or a monthly rainfall total. Monthly differences varied in direction: July had the largest increase, at +2.24 mm/day, while December had the largest decrease, at -1.53 mm/day. These daily-mean differences describe the reported monthly comparisons, not changes in monthly totals.

Changes in sunshine duration

Averaged across calendar months, mean daily sunshine duration shows a difference of -0.45 hours/day compared with the earlier reference period. This unweighted mean summarizes monthly average daily hours; it does not mean every month had the same difference. The largest monthly decrease occurred in May, with a difference of -0.99 hours/day. This marks the strongest reported monthly decrease, rather than a change shared equally across the calendar.
