Hangzhou has a humid subtropical climate with four distinct seasons.
What's the weather like in Hangzhou by month?
Each month classified as peak (best balance of weather and value), shoulder (a step in either direction), or low season.
Why visit Hangzhou during Mar–May, Sep–Nov?
The reason to come. Cherry blossom around West Lake peaks in early April (the Su Causeway and Taiziwan Park are the prime viewing spots), and the pre-Qingming Longjing tea harvest runs April 1–5.
Shoulder season (Feb, Jun, Aug, Dec) trades a small weather concession for noticeably smaller crowds and softer prices — often the sweet spot for travelers who want flexibility.
Low season (Jan, Jul) is when prices fall hardest. Expect weather extremes (heat, humidity, cold, or rain depending on the destination) and reduced hours at some seasonal businesses, but the trade-off can be worth it if budget or solitude matters more than perfect conditions.
What festivals and events happen in Hangzhou?
- Cherry Blossom and Pre-Qingming TeaLate March - early April
The cherry blossom around West Lake peaks in the first week of April; the pre-Qingming Longjing tea harvest runs April 1–5 and is the most celebrated tea event in China. Avoid the Qingming Festival public holiday weekend itself when domestic crowds flood the lake.
- Qiantang River Tidal BoreMid-September (peak around autumn equinox)
The largest river tidal bore on earth, when the autumn equinox tide funnels into the narrowing Qiantang Estuary and produces a 9-metre wave moving upstream at 25 km/h. Best viewing at Yanguan, 40 km downstream of Hangzhou — go with a tour, stay behind the police cordons, and respect the lethal force of the water.
- Mid-Autumn FestivalMid-September to early October
Mooncakes, lantern-lit walks around West Lake, and the famous "Three Pools Mirroring the Moon" pagodas lit from inside on the night of the full moon. The most poetically Hangzhou of all the Chinese holidays. The festival is a 3-day public holiday — book accommodation well in advance.
- Hangzhou International MarathonEarly November
A West Lake-circling road race that closes much of the lakefront for the morning. Worth either entering or actively avoiding the lakeside roads on race day; check current dates with the city tourism office.

Frequently asked
When is the best time to visit Hangzhou?
The best time to visit Hangzhou is Mar–May, Sep–Nov. Hangzhou has a humid subtropical climate with four distinct seasons. These months balance comfortable weather, manageable crowds, and prices that haven't yet hit peak-season highs.
When is the cheapest time to visit Hangzhou?
Low-season months in Hangzhou run Jan, Jul. Flights and hotels typically run 20-40% cheaper than peak. The trade-off is weather (which is why these months are off-peak) and some businesses operating shorter hours, especially in smaller seasonal destinations.
What's the weather like in Hangzhou year-round?
Summer averages around 30°C (86°F) and winter averages around 6°C (43°F) in Hangzhou. Hangzhou has a humid subtropical climate with four distinct seasons. Summers are genuinely brutal — July highs of 33–38°C with 80%+ humidity and the merciless plum rains (méiyǔ) of mid-June to mid-July, followed by typhoon season August through September. Winters are damp and cold without snow most years, and the lakeside wind cuts more than the temperature reading suggests. Spring (late March through May) and autumn (late September through early November) are the windows the city was designed for — the cherry blossoms, the West Lake mist, the autumn osmanthus, the golden ginkgo on Beishan Road. Annual rainfall around 1,500 mm; the lake reflection benefits from the clouds.
