Graz weather by month
Averages for 1991–2020 at the Graz_Flughafen weather station (340 m above sea level), from the WMO climate normals, next to each month's share of Austria's tourist nights (Eurostat, 2025) in 2025. The shares are for the whole of Austria, not Graz alone. These are long-term averages, not a forecast. A rainy day is one with at least 1 mm of rain.

The quietest and busiest months
In 2025, November was Austria's quietest month (4.0% of the year's tourist nights): at Graz's station that month averages a high of 8.8 °C, a low of 0.6 °C and 55 mm of rain. August was the busiest (13.3%): average high 25.2 °C, average low 13.3 °C, 126 mm of rain. The visitor figures are for the whole country, and they do not show that the weather makes a month busier or quieter, so we do not say it does.
Similar weather, quieter: ideas for August
August was Austria's busiest month in 2025 (13.3% of its tourist nights). These places had an average high within 2 °C and rainy days within 3 of Graz's in August, in a different country, and August took a smaller share of its 2025 tourist nights than August did of Austria's:
- Stuttgart, Germany: average high 25.1 °C, 9.7 rainy days; August was 12.4% of Germany's year.
- Basel, Switzerland: average high 25.3 °C, 10.2 rainy days; August was 12.8% of Switzerland's year.
- Antwerp, Belgium: average high 23.5 °C, 10.5 rainy days; August was 13.1% of Belgium's year.
Weather: 1991–2020 averages at each city's weather station (World Meteorological Organization normals in Europe, Japan Meteorological Agency in Japan); a rainy day has at least 1 mm of rain. “Quieter” compares a month with the rest of that place's own year. Try another month or place.
What these figures are
One weather station stands for Graz; places nearby can differ, especially by height or distance from the sea. For the rest of Austria, including regions and holidays, see our Austria page; for other places, the weather by city list and golden hour by place.
