Guangzhou Weather in September

September starts to cool slightly, but remains hot and humid with less rain than the summer months. Typhoon risk is still present. It's a transitional month with moderate crowds and prices.

Pack summer clothing with a light layer for evenings. An umbrella is still needed for occasional showers. Comfortable walking shoes are a must.

Mid-Autumn Festival (usually in September) is a major holiday with mooncake celebrations and family gatherings; expect crowds and higher prices. The weather can still be quite hot, so stay hydrated. Book travel early for the holiday.
