Vienna weather by month
The table uses GeoSphere Austria’s climate normals for 1991 to 2020 at the Wien Innere Stadt station, which sits in the old centre. The figures were read from its 1991 to 2020 normals workbook. Highs and lows are the averages of the daily maximum and minimum. Rainy days are days with 1 mm or more. The rain figures cover most of the 30 years, because the station doesn’t have a full record.
| Month | Average high | Average low | Rain | Rainy days |
|---|---|---|---|---|
| January | 4.2°C | -0.1°C | 37.6 mm | 7.5 |
| February | 7.0°C | 1.1°C | 33.5 mm | 6.3 |
| March | 11.0°C | 4.0°C | 46.3 mm | 7.7 |
| April | 17.4°C | 8.6°C | 39.6 mm | 6.4 |
| May | 21.1°C | 12.3°C | 78.3 mm | 9.3 |
| June | 25.7°C | 16.4°C | 82.0 mm | 9.0 |
| July | 26.9°C | 17.7°C | 80.3 mm | 8.9 |

| October | 15.0°C | 8.9°C | 47.7 mm | 7.0 |
| November | 9.5°C | 5.0°C | 42.9 mm | 6.9 |
| December | 4.7°C | 0.7°C | 39.9 mm | 7.7 |
These are averages over 30 years, so they’re a guide and not a forecast. A single week can run several degrees either side, so pack for the range in the table and check the forecast before you travel. The station is in the old centre.
Spring: March to May
March is still a cold-weather month, with an 11.0°C high and a 4.0°C low. April jumps to 17.4°C by day, and May reaches 21.1°C. The rain’s the other change. April is one of the drier months at 39.6 mm over 6.4 days, while May roughly doubles that to 78.3 mm over 9.3 days.
For March, you’ll want a warm coat and something waterproof. For April, a jacket and a sweater cover most days, and the evenings at 8.6°C still need the layer. In May you can usually drop to a light jacket, and a small umbrella’s worth carrying. The parks fill up once it’s warm, and the Stadtpark is the easy one to reach from the centre. The March, April and May events pages list what is on.
Summer: June to August
June, July and August all have highs between 25.7°C and 26.9°C and lows between 16.4°C and 17.7°C. These are also among the wettest months, with 82.0 mm in June, 80.3 mm in July and 73.8 mm in August. The rain days run from 8.0 to 9.0 a month, so expect a shower or two a week and not a washout.
GeoSphere counts about 27 days a year with a high of 30°C or more at this station, and about 80 days with a high of 25°C or more. Those hot days fall in summer, so it’s smart to bring light clothes, a hat and a water bottle for sightseeing in the middle of the day. Evenings stay mild at around 17°C, and you won’t need more than a thin layer. The water’s where many people go to cool off, from the boats on the Alte Donau to the beaches at Strandbad Gänsehäufel and the long Donauinsel. See the June, July and August events pages for dates.
Autumn: September to November
September still feels like summer, with a 21.6°C high and a 13.8°C low, though it gets 67.3 mm of rain over 7.2 days. October drops to 15.0°C and 8.9°C, with 47.7 mm over 7.0 days. By November the high is 9.5°C and the low 5.0°C, and the rain is down to 42.9 mm over 6.9 days.
September’s the month to pack light layers and an umbrella. October needs a proper jacket and closed shoes. November calls for a warm coat, a scarf and gloves in the evening. The Kahlenberg lookout shows the Danube and the city spread out below. The September, October and November events pages cover the season, and the Christmas markets guide lists the dates for the markets.
Winter: December to February
December averages a 4.7°C high and a 0.7°C low, January 4.2°C and -0.1°C, and February 7.0°C and 1.1°C. January is the coldest month, and the average low sits just under freezing. The station has about 45 days a year when the temperature falls below 0°C, and an average of 15 of them are in January.
Winter is also dry, and February is the driest month of the year. It has 33.5 mm, and January has 37.6 mm over 7.5 days. You’ll want a warm coat, a hat, gloves and shoes with grip, with a waterproof layer for the days that bring rain. The cold is also the season of the Christmas markets, and the tram is the easiest way to move between them. Inside, the coffee houses are made for a cold afternoon, and you won’t be hurried. The December, January and February events pages list what is on.
