When to Go
Vienna is warm and sunny in spring and autumn; July and August can be hot and stormy, with temperatures reaching well above 32ºC (90°F). From November through March, winter can get cold, with snow falling in January and February; lows of -12ºC (10°F) are frequent. Culturally, high season in Vienna is May, June, and September, when festivals, marathons, concerts, and operas are in full swing. In winter, the glittering Christmas markets attract international crowds and during the Ball Season, December through February, nearly 500 balls take place, hosted by nearly every profession or trade; the Coffee House Owners Ball is the biggest, the Opera Ball the most internationally famous. Many Viennese leave the city in July and August, so the city tones down some, though it fills with tourists.
Christkindlmarkt (Christmas Market). In Vienna the biggest Christmas market goes up in mid-November in the plaza in front of the city's Rathaus (town hall); there are more than 30 smaller ones dotted around town, including outside Schönbrunn and the Belvedere Palace, in the Spittelberg Quarter on the Freyung square, and in front of Karlkirche on Karlsplatz.
Donauinselfest (Danube Island Festival). Held in late June, this is Europe's largest open-air music fest, attracting 3 million visitors each year. Entrance is free. Donauinsel, Vienna, Vienna. www.donauinselfest.at.
