Shanghai Weather & Climate Guide 2026

Month-by-month weather, best times to visit, and what to pack for Shanghai.

Shanghai is China's largest city and a global financial hub, where gleaming skyscrapers tower over historic colonial-era buildings along the iconic Bund waterfront. A dynamic metropolis blending East and West, Shanghai offers world-class dining, vibrant arts and culture, and remarkable contrasts between ancient gardens and futuristic architecture.

Shanghai has a humid subtropical climate with four distinct seasons. Summers are hot and humid with frequent rain and occasional typhoons tracking up the coast; winters are cold and damp with occasional frost but rarely snow. Spring is pleasant but often foggy and rainy. Autumn is the most comfortable and scenic season with clear skies and golden trees.
