Climate Change Chart of Vaduz, Liechtenstein

Overview of climate changes

Temperature changes

Across calendar months, the unweighted mean of monthly mean temperatures shows a difference of +2.24 °C compared with the earlier reference period; this summarizes the month-by-month averages rather than daytime maximum temperatures or a continuous change over time. The largest monthly increase was in January, with a difference of +5.32 °C. This identifies the strongest increase among the monthly mean temperature differences, not a change shared by every month.

Changes in snowfall

The unweighted mean of monthly mean daily snowfall, averaged across calendar months, shows a difference of +3.54 mm/day compared with the earlier reference period. This summarizes monthly averages rather than day-weighted annual snowfall or monthly totals. The largest monthly increase in mean daily snowfall was in January, with a difference of +11.47 mm/day. This marks the strongest increase among the monthly differences; it does not imply the same change in every month.

Changes in rainfall

Averaged across calendar months, mean daily rainfall shows a difference of +0.90 mm/day compared with the earlier period. This is an unweighted average of monthly means, not a day-weighted annual average or a monthly rainfall total. The largest monthly increase in mean daily rainfall occurred in August, with a difference of +2.78 mm/day. By contrast, November had the largest decrease, a difference of -0.29 mm/day; these are monthly mean daily amounts, not totals for either month.

Changes in sunshine duration

Averaged across calendar months, mean daily sunshine duration shows a difference of -0.32 hours/day, indicating a lower unweighted mean across the monthly averages in the more recent period. It is not a day-weighted annual figure or evidence of a continuous trend. Monthly differences were not uniform: May had the largest decrease, a difference of -0.74 hours/day, while the largest increase was in February, with a difference of +0.09 hours/day. These comparisons describe mean daily sunshine hours for the named months.
