These temperatures aren't the only things that drop in September the length of the days does too. The average high temperature decreases from 23☌ to 18☌, while the average low drops from 13☌ to 10☌. The first weeks of September are undoubtedly the best time of the month to visit. Both these high and low temperatures fall significantly in the course of the month, though.

If you're visiting Vienna in September, make sure to bring a jacket. In the afternoons, the mercury climbs to a still comfortable 19☌ high, but at night, it drops to a chillier low temperature of 10☌. The average temperature in Vienna in September is 15☌, which is already four degrees fewer than it was in August, but still also five degrees more than it will be in October. There are fewer tourists, but the weather is definitely still good enough to spend your days outside, walking from, say, museum to museum. September, although it is slightly cooler, has the big advantage that it is much quieter than the two peak summer months of July and August. It marks the end of the summer season in the city and in Austria in general, a season that was very sunny and warm. September is the last month of the year to enjoy comfortably warm temperatures in Vienna, temperatures that allow you to walk around in a T-shirt in the afternoon and sweater or light jacket at night.
