Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +0.62 °C in the more recent period; this unweighted comparison summarizes the monthly means, rather than describing daytime maximum temperatures or a continuous change through time. The largest monthly increase in mean temperature was in March, with a difference of +0.87 °C. This identifies the strongest monthly increase among the supplied temperature facts, not a rise shared by every month.

Changes in rainfall

Averaged across calendar months, mean daily rainfall had a difference of -0.17 mm/day in the more recent period. This is an unweighted comparison of monthly averages of daily rainfall, not a difference in annual or monthly rainfall totals. The monthly pattern was not uniform: March recorded the largest decrease in mean daily rainfall, a difference of -1.65 mm/day, while June had the largest increase, a difference of +0.82 mm/day. These are differences in daily averages for those months, not totals accumulated over each month.

Changes in sunshine duration

Averaged across calendar months, mean daily sunshine duration shows a difference of -0.06 hours/day in the more recent period. The unweighted mean summarizes the calendar-month averages; it does not imply that every month had less sunshine or establish a continuous trend. The largest monthly decrease in mean daily sunshine was in June, with a difference of -0.48 hours/day. In contrast, April had the largest monthly increase, a difference of +0.34 hours/day; these month-specific comparisons show that the changes varied by month.
