Venice’s climate is shaped by its lagoon setting and proximity to the Adriatic Sea. Summers (June–August) are warm to hot and often humid, with average highs of 28–30°C and nights rarely dropping below 18°C. While the sea breeze can offer relief, humidity can make the heat feel more intense. Afternoon thunderstorms are possible, but rain is generally moderate. The sea is warmest in July and August, reaching 25–26°C, ideal for swimming at the Lido. Sunshine peaks in summer, with up to 9 hours per day.
Winters (December–February) are cold and damp, with average highs of 6–8°C and lows near 1°C. Fog is frequent, and light frosts are common at night. Snow can fall once or twice a year but rarely accumulates. The city is prone to acqua alta (high water) during autumn and winter, when a combination of tides, wind (especially the sirocco), and rain can flood low-lying areas. Spring (March–May) and autumn (September–November) are transitional, with mild temperatures (13–22°C), increased rainfall, and variable weather. The bora wind from the northeast can bring sudden cold spells, especially in spring. Venice enjoys about 2,000 hours of sunshine annually, with the brightest days from May to August.
