Highs around 21C, thinning crowds after the first week, and the start of the cultural season as the opera and concert halls reopen.

With highs around 21°C, September is outdoor weather: prioritize viewpoints, parks and long walks.
Schonbrunn Palace
TipBuy a timed-entry ticket online, since the palace admits by slot and same-day slots sell out by midday in season. Take the earliest slot around 8:30am or the last two hours of the day to dodge the tour-group peak; the vast gardens, the Gloriette hill and the maze are free, so save the paid interior for the Grand Tour and spend the rest outdoors.
Hofburg Palace
TipThe single Sisi Ticket covers the Imperial Apartments, the Sisi Museum and the Silver Collection here plus the Schonbrunn Grand Tour, so buy it once if you plan both palaces and skip two separate queues. Enter the Imperial Apartments right at 9am opening; the audioguide is included, and the courtyards, Heldenplatz and the arcades are free to walk through any time.
St. Stephen's Cathedral (Stephansdom)
TipThe rear standing area is free, but the nave, the catacombs tour and the two towers each cost separately, so decide before you go in. The south tower's 343 steps give the better climb and skyline; the north tower has a lift to the Pummerin bell and shorter queues, and the tiled roof pattern is best photographed from the Stephansplatz corner opposite.
Prater & Riesenrad
TipThe park itself and its long chestnut avenue are free and open at all hours; only the Riesenrad ferris wheel and the fairground rides cost money. Ride the Riesenrad near sunset for the best light and shortest wait, or skip it and walk the Hauptallee instead, then eat at a garden restaurant like Schweizerhaus for Stelze and a half-litre of beer.
