Vienna lies in the far east of Austria on the plain of the Danube, at around 200 metres elevation and approximately 48.21°N, 16.37°E. It has a moderately continental climate at the meeting point of Atlantic and continental influences, giving it four clear seasons — warm summers and cold, grey winters — with a wide swing in temperature across the year and no distinct rainy season.

Summer, from June to August, is warm and one of the wetter times of year. July, the warmest month, averages highs around 26–27°C and lows near 15°C, and increasingly frequent heat waves push temperatures past 30°C and occasionally into the mid-thirties. Evenings stay mild, and the warm weather draws people out to the city's gardens and wine taverns, though brief but intense afternoon thunderstorms are common.

Winter is cold and often overcast, with January the coldest month — daytime highs only a few degrees above freezing and nights around or below 0°C. Cold spells driven by Siberian air can drop temperatures to -15°C or lower. Snow falls fairly often, averaging around 50 cm a year, but usually in thin, atmospheric dustings rather than heavy storms, and the city keeps functioning smoothly through it.

Vienna receives moderate precipitation of roughly 620–720 mm a year, spread across the seasons but with a clear summer maximum when convective storms are most active; late winter and early spring are the driest months. Autumn rain tends to be lighter and more persistent, and a share of winter precipitation falls as snow. Live rainfall, humidity, and pressure readings for the city are shown in the panels above.

Spring and autumn are attractive transitional seasons — spring can be changeable with late frosts and sudden showers, while autumn is often drier and milder than places on similar latitudes, with golden foliage in the Vienna Woods. Humidity is relatively high in the colder months, and Vienna tends to see less snow than the Austrian regions closer to the Alps.
