Climate Change Chart of Dresden, Germany

Overview of climate changes

Temperature changes

Monthly mean temperatures were higher by an unweighted mean difference of +2.10 °C averaged across calendar months; this summarizes the monthly means rather than a day-weighted annual average, and does not imply that every month changed by the same amount. The largest monthly increase was in January, with a difference of +4.90 °C compared with the earlier reference period. These are monthly mean temperatures, not daytime maximum temperatures.

Changes in snowfall

Mean daily snowfall showed an unweighted mean difference of -0.51 mm/day averaged across calendar months, a lower mean in the more recent period rather than a day-weighted annual average. Monthly differences included the largest increase in January, with a difference of +1.05 mm/day, and the largest decrease in February, with a difference of -2.68 mm/day. These are daily mean amounts, not monthly snowfall totals, and the aggregate difference does not describe every month's change.

Changes in rainfall

Mean daily rainfall was higher by an unweighted mean difference of +0.21 mm/day averaged across calendar months, not a day-weighted annual average or a change in monthly totals. The month-to-month pattern was not uniform: October had the largest increase, a difference of +0.76 mm/day, while April had the largest decrease, a difference of -0.30 mm/day. These figures describe daily mean amounts for those months, rather than accumulated rainfall totals.

Changes in sunshine duration

Mean daily sunshine duration had an unweighted mean difference of -0.09 hours/day averaged across calendar months, indicating a lower mean in the more recent period; this is not a day-weighted annual average. Monthly differences varied: the largest increase was in July, at +0.62 hours/day, whereas the largest decrease was in January, at -1.07 hours/day. The overall mean therefore should not be read as describing the change in every month.
