What's the weather like in Venice in October?

The weather in Venice in October is usually mild: expect temperatures between 7°C and 15°C (45°F to 59°F), with either clear blue skies or thick fog. Keep an eye out for the acqua alta (high tide): in 2018, runners in the Venice Marathon ended up finishing with their feet in the water. The Venice Marathon is an October race, so choose a flexible, layerable outfit for running.
