Chongqing Weather in September

September feels warm and damp

September is autumn in Chongqing, but it can still feel like summer. Highs reach 29°C, and humidity sits at 76%, so a walk through the hilly streets can leave you sticky. Rain falls on 16 days, often making steps and slopes slippery.

It's a better month for short outings than full days on exposed trails. Duck into the Three Gorges Museum or take a break in a teahouse around Ciqikou when the rain sets in. The Yangtze River Cableway can be fun, but low cloud may hide the views. August is hotter; October is cooler and drier.

Pick your plans around the rain

With only 3.1 hours of sun a day on average, don't count on clear skies for skyline views. Keep Hongya Cave's riverside walk or a ride on the cableway flexible, and save indoor sights for wet spells. For a hill walk, avoid slick stairways after heavy rain.

Travelling with kids? Choose a short visit to Chongqing Zoo, then head indoors if the afternoon turns muggy.

Crowds and local dates

September is usually quieter than the summer holiday period, and prices can ease after August. But crowds and hotel rates may rise around the Mid-Autumn Festival, which sometimes falls in September. China's National Day holiday begins on October 1, so late September can also get busier as people travel.

A useful local tip: Hongya Cave's steps are steep and can be crowded near sunset. Take the metro to Xiaoshizi, then use the riverside entrance rather than tackling the climb from the upper road in wet weather.
