Has the climate in Salzburg changed?

Salzburg has warmed about 3.9°F since 1971.

About 0.7°F per decade, measured from Salzburg's official daily weather records, 1971–2025. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.

Is that a lot? Salzburg's warming is broadly in line with other cities in Austria — neither unusually fast nor unusually slow.

What has actually changed

Each card compares the 1970s (the first ten years of the record) with recent years (the last ten) — the same span the headline and the chart use.

Each bar is one year. Most recent years sit above the older ones. Some recent years still came in cool — warming is a slope, not a straight climb.

In day-to-day terms, that long-term shift shows up as about 8 fewer freezing nights a year and about 2 more days above 90°F compared with the 1970s.

When in the year the change shows up

How much warmer each month is now than in the 1970s. Useful if you garden or care about a particular season — otherwise the headline above already has the answer.

June has warmed the most — about 2.3°F. The warming runs across the whole year, not just one season.

Methodology & sources

Temperature — 1991–2020 normals computed from 30 years of daily observations at Salzburg, a weather station, about 3 km from the city centre. The underlying daily records come from NOAA's global station network.
