Climate Change Chart of Munich, Germany

Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +1.88 °C in the more recent period; this is an unweighted comparison of monthly means, not a day-weighted annual figure or a measure of daytime maximum temperatures. The largest monthly increase was in January, with a difference of +4.90 °C. By contrast, May had the largest decrease, at a difference of -0.12 °C; these monthly extremes show that the aggregate shift did not apply uniformly across calendar months.

Changes in rainfall

Mean daily rainfall, rather than monthly totals, averaged across calendar months shows a difference of +0.59 mm/day compared with the earlier reference period. The mean is an unweighted average of the calendar-month means, so it describes the overall monthly pattern rather than rainfall on every day. The largest monthly increase occurred in August, with a difference of +1.28 mm/day; the largest decrease was in April, at a difference of -0.14 mm/day. These contrasting monthly differences add context to the aggregate change without implying that each month followed the same direction.

Changes in sunshine duration

Mean daily sunshine duration, averaged across calendar months, shows a difference of -0.34 hours/day in the more recent period. This unweighted average of monthly means summarizes the overall comparison, not the daily sunshine experienced on every date. The largest monthly decrease was in May, with a difference of -0.79 hours/day. In June, the largest increase was a difference of +0.13 hours/day, illustrating that the monthly pattern was not uniform.

Changes in snowfall

Mean daily snowfall, not monthly totals, averaged across calendar months shows a difference of -0.33 mm/day compared with the earlier reference period. The unweighted monthly-mean comparison describes the aggregate, and should not be read as a change of the same size in every month. The largest monthly increase occurred in January, with a difference of +1.60 mm/day; the largest decrease was in February, at a difference of -1.54 mm/day. The contrasting directions highlight variation between these monthly differences, without implying that snowfall was absent in either period elsewhere.
