October/November is proper autumn in Vienna. You can expect periods of mild weather and sunshine especially in October as well as foggy, cold and rainy days and even the first snow in November. The average daily temperature hovers around a bearable 15 degrees Celsius at most, and can drop to around 0 degrees at the least. We recommend bringing warm clothing that you can wear in layers. A wind- and waterproof jacket as well as proper shoes are very useful. Please be aware that depending on whether you catch a sunny or rainy phase, the temperatures can vary significantly.
