May and June
Go nowLong days, gardens open, and the season still running
The best combination the city offers: warm without the August heat, light until late, palace gardens and Heurigen in use, and the opera and concert halls still in season until the end of June. Prices are high and it is worth it.
September and October
Go nowThe season restarts, and so does the wine
Warm days, cool evenings, the cultural season opening again after the summer break, and the new wine arriving in the taverns on the hills. The single best window if you want both the music and the wine, and slightly cheaper than early summer.
April
Worth it, butUnreliable weather, everything open, lower prices
Swings between shirtsleeves and sleet without warning, and the gardens are only just waking up. Everything indoors runs normally and rooms cost noticeably less. Easter moves between late March and late April and fills the city when it lands.
July and August
Worth it, butHot, busy, and the opera is dark
The warmest and most crowded weeks, with outdoor cinema, festivals and the Danube island in full use. The catch is that the State Opera and the main concert halls are closed for the summer, and what replaces them is aimed at visitors. Fine if you came for the city; a disappointment if you came for the music.
December
Worth it, butChristmas markets, and very short days
Markets across the city from late November, the concert season at its peak, and daylight that gives up by four in the afternoon. Cold and crowded, and genuinely atmospheric. Around Christmas itself much of the city closes for two days, transport included.
November
Think twiceThe grey month, before the markets open
Damp, dark and without either the autumn colour of October or the December markets, which mostly start in the last week. The museums and concert halls are at their emptiest and their cheapest, and that is the whole of the case for coming.
January, February and March
Think twiceCold, dark, and the ball season if you want it
The coldest stretch, with short days and a real chance of grey weeks. There is one reason to come anyway: the ball season runs from mid-November to Shrove Tuesday, which moves between early February and early March, and several hundred balls happen in that window. Otherwise this is an indoor trip.
