Vienna
April to May and September to October.
April, May, September and October give the best mix of mild weather and manageable queues. July and August are warm and busy at the palaces, and December fills up with visitors for the Christmas markets. January and February are cold and grey, which suits museums and coffee houses better than long walks.

1 to 5 °C · about 7 rainy days a month
Highs sit around 4 to 5 degrees and nights are near freezing, with short daylight. In December the Christmas markets draw large crowds, especially in the evenings.
What to wear: Wear a warm coat, hat and gloves, and shoes with grip for wet cobbles. Indoors is well heated, so dress in layers.
Rain is spread across the year, with May to August the wettest months, so keep an indoor plan for each day. The Kunsthistorisches Museum, the Albertina, the Belvedere and the Natural History Museum can each fill half a day, and a coffee house is the standard way to wait out a shower. The Ferris wheel and the Schönbrunn gardens lose most of their appeal in low cloud.
July and August afternoons reach about 27 degrees, which is warm rather than punishing. The Ringstrasse, the Schönbrunn park and the Naschmarkt have little shade at midday, so do them in the morning or evening. Spend the hottest hours in a museum or a cool church, and carry water, since the tap water is safe to drink.
