New Territories Weather in September

September: hot and damp

September still feels like summer in the New Territories. Highs reach 29°C, with warm nights and humidity at 81%. Rain falls on 17 days, often making afternoons sticky and paths slick. It's cooler and less rainy than August, but October is much more comfortable.

You can explore Sha Tin's museums or take a short stroll along the Shing Mun River between showers. Sai Kung's waterfront is pleasant for a meal, but boat trips and exposed coastal walks can be disrupted by rain. Save longer hikes on the MacLehose Trail for a drier month.

Mid-Autumn evenings

The Mid-Autumn Festival often falls in September, though its date changes and it can land in October. Families gather to admire the moon, share mooncakes and carry lanterns. The festival brings a warm local feel, but busy parks and public transport can make the evening less peaceful.

Travelling with kids? Look for lantern displays around Sha Tin Park, where you can combine an evening stroll with a visit to nearby New Town Plaza.

Quieter than peak season

September is generally less crowded than October to February, the New Territories' more comfortable travel season. Prices are often softer than in those popular months, though demand can rise around the Mid-Autumn holiday. School-term routines also mean fewer family holiday crowds than in summer.

If you hate crowds, visit the Ten Thousand Buddhas Monastery on a weekday. Its long staircase can be slippery after rain, so take your time and avoid the climb during a downpour. The humidity and frequent showers make September a less comfortable choice for strenuous sightseeing, but indoor stops and flexible plans still work well.
