Good to Know
- May through October is the best window for visiting—warm, sunny weather with comfortable temperatures for walking and sightseeing.
- December through February brings cold temperatures near or below freezing at night, frequent fog, and risk of acqua alta (high-water flooding that submerges streets), making outdoor exploration challenging.
- Snow is rare but possible in winter; expect light accumulation only. Pack layers and an umbrella year-round since rainfall is frequent though typically light.
- Summer is warm and humid (22–28°C (72–82°F)) but can feel muggy; July and August have slightly less rain than spring and autumn but see higher tourist crowds.
- Spring (March–May) is cool and rainy early on, warming gradually by May. April and May offer pleasant weather without peak summer crowds.
- Autumn (September–November) cools steadily but is stormy and sees the highest flooding risk in October–November—avoid late autumn for outdoor planning if acqua alta is a concern.
