Venice’s humid subtropical climate brings hot, sticky summers, chilly winters, and the famous acqua alta (high water) that periodically floods the city in autumn and winter. Understanding Venice’s seasonal rhythms is essential for a comfortable visit. This month-by-month guide breaks down Venice’s weather in detail.
Venice Climate Overview
Venice has a humid subtropical climate (Cfa) moderated by the Adriatic Sea and the lagoon. Average annual temperature is 14 degrees Celsius (57 Fahrenheit). July is the hottest month averaging 28 Celsius (82 Fahrenheit) with high humidity. January is the coldest at 7 Celsius (45 Fahrenheit) for highs. Annual rainfall totals about 750 millimetres (30 inches), with autumn being the wettest season.
Acqua alta (high water) occurs primarily from October through January when high tides, wind, and atmospheric pressure combine to flood low-lying areas, particularly St. Mark’s Square. The city has installed elevated walkways for these events. Fog (nebbia) is common in winter, adding an ethereal quality.
Spring (March to May)
Spring is Venice’s most pleasant season. March warms from 12 Celsius (54 Fahrenheit) to May’s 21 Celsius (70 Fahrenheit). The city’s gardens bloom and the tourist season begins. Easter can bring crowds. May delivers near-perfect conditions for walking and gondola rides. Pack layers and a light rain jacket. The Biennale art and architecture exhibitions often open in spring (alternating years).
Summer (June to August)
Venice summers are hot, humid, and crowded. July and August average 28 Celsius (82 Fahrenheit) with humidity making it feel warmer. The narrow streets trap heat, and crowds peak. Mosquitoes are a nuisance near the canals. Despite the challenges, summer delivers long evenings and the city’s most vibrant energy. Book everything well ahead. Pack light clothing, mosquito repellent, and a water bottle (Venice has excellent free drinking fountains).
Autumn (September to November)
September remains warm (24 Celsius / 75 Fahrenheit) but crowds ease after the first week. October cools and brings golden light perfect for photography. November is the rainiest month and acqua alta becomes more frequent. The Venice Film Festival in late August or early September draws stars to the Lido. Autumn is a good season for a slightly calmer Venice experience.
Winter (December to February)
Winter is Venice’s quietest, cheapest, and most atmospheric season. Highs average 7 to 9 Celsius (45 to 48 Fahrenheit). Fog shrouds the canals in mystery. Acqua alta is most frequent from November through January. The Carnival in February transforms the city with masks and costumes. Pack warm layers, waterproof footwear, and a coat. This is the season for having Venice almost to yourself.
