What Is the Weather Like in Hangzhou?

Hangzhou has a climate with meaningful month-to-month changes. Summers can be warm or hot, winters are cooler, and spring and fall often decide whether a trip feels smooth or weather-complicated. The Hangzhou climate by month shows average highs from about 48F (9C) in the coolest part of the year to about 91F (33C) in the hottest part. Annual precipitation averages roughly 54.7 inches, and snow or ice can be a real winter factor.

Weather in Hangzhou changes the feel of the city because this is a place where comfort depends on more than the number on a forecast. A mild month can make metro transfers, neighborhood walks, outdoor meals, and photography feel easy. A difficult month can make the same itinerary feel slower, sweatier, colder, wetter, or more dependent on indoor breaks.

Best Month to Visit Hangzhou for Weather

October is the best month to visit Hangzhou for weather in a typical year. Average daytime highs are near 76F (24C), while nights are around 57F (14C). Precipitation averages 2.8 inches, so the month is usually more comfortable than the wetter, hotter, or colder parts of the year.

What makes October stand out is balance. It is not necessarily perfect every day, but it usually gives travelers the best combination of outdoor comfort, manageable weather risk, and enough flexibility for a first-time trip. If hotel prices or crowds rise during this period, that popularity is at least partly weather-driven.

Worst Month to Visit Hangzhou for Weather

August is the worst month to visit Hangzhou from a pure weather perspective. Average highs are around 91F (33C), and nights are near 76F (24C). The month also brings heavy rain, averaging about 6.8 inches, which can make long outdoor days less comfortable.

Heat is the main problem. Even if mornings are workable, afternoons can make long walks tiring, and travelers who dislike heat may end up planning the day around shade and air conditioning. Lower hotel prices or fewer visitors can make August acceptable for flexible travelers, but it is not the month I would choose for the best weather in Hangzhou.
