Vienna weather by month
June to August is the best time for a warm-weather trip to Vienna, with daytime averages reaching 26°C in July and August. The catch is rain: July averages 12 rainy days, so summer still calls for flexible outdoor plans. May and September offer a gentler alternative at around 20°C, particularly if you prefer walking without as much midday warmth. Winter suits travellers happy to wrap up and spend less time outdoors.

Spring: a chilly start, then comfortable walking weather
March is still a layers-and-coat month: afternoons average 10°C, but nights near 1°C make early starts and late returns feel distinctly cold. April is a more comfortable choice for spending time outside, with daytime temperatures around 16°C and more sunshine than March. Keep a jacket handy rather than packing only for mild afternoons. By May, the daytime average reaches 20°C, making it a good fit for travellers who want warmth without midsummer temperatures. There is a catch, though: May has 12 rainy days on average, compared with 9 in April. Pack a waterproof and leave room to rearrange outdoor plans.
Summer: the warmest choice, but not a dry season
June brings average afternoons of 24°C, warm enough for light clothing while leaving a useful margin below the midsummer peak. July and August both average 26°C by day and 16°C at night, so evenings are milder than in spring, though a light layer remains useful. All these months average 7 hours of sunshine, making summer the strongest choice if warmth and sun matter most. August has a slight practical edge for outdoor plans, with 10 rainy days against 12 in June and July. July is also the wettest month. Plan breaks from midday warmth and carry a waterproof rather than assuming clear weather.
Autumn and winter: September stands apart
September is the easiest autumn choice for an outdoor-focused visit: days average 20°C and nights 12°C, so a light layer should see more use than a heavy coat. October drops to 15°C by day and 7°C at night, making warmer layers more important for lingering outside. November feels much closer to winter, with 9°C afternoons and limited sunshine. December and January call for a proper winter coat, gloves and warm footwear: daytime averages are only 4°C and 3°C respectively, with nights below freezing. February improves to 6°C by day but remains cold after dark at -2°C. Winter is a weaker fit if your main aim is long, comfortable days outdoors; plan shorter walks and regular indoor breaks.
