Guilin Weather in September

September weather

Guilin stays warm in September, but it's less hot than August. Days reach about 29°C, and evenings feel mild. The air is still very humid, and rain falls on around 12 days. Showers can interrupt a Li River cruise or muddy paths around the karst hills, so keep your plans flexible.

Cloud and rain can soften the views of the limestone peaks. Still, a clear spell is lovely for a boat trip from Guilin to Yangshuo or a walk beside the Two Rivers and Four Lakes. Reed Flute Cave is a good rainy-day choice. Skip long hill walks when paths are slick.

Events and crowds

The Mid-Autumn Festival sometimes falls in September, though its date changes each year. If it does, you'll see mooncakes in shops and families gathering under the full moon. It's a major Chinese holiday, so trains and popular sights can get busier around the festival.

If you hate crowds, September is a useful shoulder-season choice. Summer's peak travel rush has eased, while October to December is generally a more popular time to visit. Prices are often gentler than in those cooler months, but can rise around Mid-Autumn.

Make the most of your trip

With fair rather than reliably sunny weather, plan outdoor sights around the day's conditions. A rainy morning doesn't have to spoil your visit: take a Li River cruise when skies clear, or head underground at Reed Flute Cave.

For the river route, check whether your ticket is for the full Guilin-to-Yangshuo cruise or a shorter trip. Water levels and visibility can affect the experience after rain. If you're travelling with kids, the cave's colourful rock formations make an easier wet-weather outing than a slippery riverside walk.
