Climate Change Chart of Salzburg, Austria

Overview of climate changes

Temperature changes

The unweighted difference between monthly mean temperatures, averaged across calendar months, is +1.83 °C; this describes the average of the monthly means, not daytime maximum temperatures or a day-weighted annual average. The largest monthly increase was in January, with a difference of +4.70 °C. By contrast, May had the largest monthly decrease, a difference of -0.05 °C; these extrema show that the overall mean does not describe the change in every month.

Changes in snowfall

Mean daily snowfall, averaged across calendar months, had an unweighted difference of +0.10 mm/day. This is an average of monthly daily means, not a monthly snowfall total, and the rounded comparison does not establish that snowfall was absent or unchanged beyond the displayed precision. The largest monthly increase in mean daily snowfall occurred in January, with a difference of +5.28 mm/day. The largest monthly decrease was in December, a difference of -2.40 mm/day; these monthly extremes need not match the small average difference across calendar months.

Changes in sunshine duration

Mean daily sunshine duration had an unweighted difference of -0.44 hours/day, averaged across calendar months. This summarizes the monthly mean daily hours rather than implying an identical change in each month. The largest monthly decrease was in May, with a difference of -1.52 hours/day; in July, the largest monthly increase was a difference of +0.32 hours/day. The opposing monthly differences help show why the across-month mean does not represent every month.

Changes in rainfall

Mean daily rainfall, averaged across calendar months, had an unweighted difference of +0.78 mm/day compared with the earlier reference period; this is an average of monthly daily means, not a monthly total or day-weighted annual average. The largest monthly increase in mean daily rainfall occurred in May, with a difference of +1.84 mm/day. This monthly contrast provides context for the across-month average but does not mean rainfall rose by the same amount in every month.
