When to go, and when not to
May and October are the strongest months to visit Wuxi. May brings a high of 26.3C, a low of 17.0C, 110mm of rain, and 8.1 hours of sunshine per day, while October offers a high of 23.3C, a low of 16.0C, only 76mm of rain, and 6.7 hours of sunshine per day, together giving a comfortable balance of warmth, dryness, and daylight.
These same months are also the peak season, so travelers should expect higher demand at that time. Outside of the peak, June is the wettest month with 279mm of rain, and August is the hottest with a high of 33.4C, closely followed by July at 33.1C; the off-season months of February, July, and August are cheaper but come with either cold, damp conditions or intense heat and humidity.
