Rain season
Istanbul spans two continents — winters are wet and cold (December–February), summers warm and largely dry (July–August). Autumn (October–November) brings the most intense rain as Mediterranean fronts interact with cooler air. Annual totals average 840mm. The city's hilly topography and Bosphorus coastal position can produce highly localised heavy rain events.
