Hangzhou travel guide — where to stay, what to do, and where to eat in Hangzhou, Zhejiang, China.

Hangzhou has a humid subtropical climate with four distinct seasons: mild, damp winters (December-February, rarely dropping much below freezing but feeling cold and raw due to humidity and limited indoor heating), hot, very humid summers (June-August, typically 30-38°C/86-100°F), a distinct 'plum rain' (meiyu) season of prolonged drizzle in June, and short but very pleasant spring and autumn shoulder seasons. Typhoon-related heavy rain can affect the region July-September, though Hangzhou itself is inland enough to usually see only heavy rain rather than direct typhoon landfall. The best months for sightseeing are late March-May (spring) and late September-November (autumn), when West Lake's gardens are at their best and humidity is manageable.
