Your April weather guide
MildWeather in Vienna in April
April is a good time for Vienna if you prefer mild weather for walking rather than reliable warmth. Average daytime highs reach about 16°C, but nights fall to around 6°C, so a coat still earns its place in your bag. With about 9 rainy days, you also need plans that can bend around wet weather. For a UK traveller, the appeal is comfortable afternoons when conditions cooperate; the catch is chilly evenings and no guarantee of sunshine.

Nights average 5.5°C; one night in ten drops to 0.9°C or lower, so pack a layer for evenings - it is genuinely cool after dark.

Comfortable for walking, less so for sitting outside
Vienna in April suits travellers who are happy to keep moving and adjust their layers. The average afternoon is mild rather than warm, so a jumper and a light coat are a more useful starting point than summer clothes. There can be warmer spells: the warmest 10% of days reach 21.5°C or more, making outdoor breaks more appealing. Cold is still part of the picture, though, with the coldest 10% of nights dropping to 0.9°C or below. Pack something warmer for late returns, and do not judge the evening by how pleasant it felt in the afternoon. Layers give you room to adapt without dressing for winter all day.
Keep outdoor plans flexible
Rain is a practical drawback in April, but it need not rule out a walking-focused trip. Bring a waterproof outer layer and shoes you can comfortably wear on wet streets, rather than relying on a warm-weather forecast when packing. Sunshine averages about 5.9 hours within 13.4 hours of daylight, so there is a useful amount of light for flexible plans, but daylight does not mean clear skies. Leave room to move outdoor time around the forecast and take indoor breaks when it turns wet. If your main aim is dependable warmth, April is a compromise; it works better when you are content with mild weather and occasional cold.
