#At a Glance
September looks like the start of autumn on a calendar and feels like the end of summer in the street. It is 31°C by day, with about fifteen wet days and 321mm of rain, and typhoon signals average nearly four days. But the month holds Hong Kong's most beautiful festival. Mid-Autumn falls on Wednesday 15 September 2027, with lanterns in the parks, mooncakes in every bakery, and the Tai Hang Fire Dragon winding through the back streets for three nights. Late in the month the humidity at last begins to drop.
#Weather in Hong Kong in September
Hong Kong in September averages 26–31°C (79–88°F) with around 15 days of rain, and crowds are medium.
The Hong Kong Observatory's 1991–2020 normals give September a high of 31°C / 88°F and a low of 26°C / 79°F, with about 15 wet days, 321mm of rain and humidity of 78%.
What that actually means for your trip:
- The first half is summer. Plan as you would for August.
- The last week can be lovely, with a first hint of dry air.
- Thunderstorms ease, from about nine days in August to about five.
- Storms are still strong. September's signal days are second only to August's.
#The Signals in September
Signal No. 8 averages about two September days in every three years. Keep one day free, and check the Observatory each morning.
- Typhoon No. 3: strong wind. Life continues, but cancel boats and long hikes.
- Typhoon No. 8: gales. Schools and most offices shut, ferries stop, buses thin out and halt, and the MTR keeps running.
- Rainstorm warnings: amber alerts you, red means leave the hills, and black means stay indoors or take shelter.
A storm can move outdoor Mid-Autumn events, so check before you set off.
#Mid-Autumn, Night by Night
Dates come from the Observatory's lunar table, and the detailed programmes follow nearer the time.
- Tuesday 14 to Thursday 16 September: the Tai Hang Fire Dragon, a dragon of straw stuck with burning incense, carried through the small streets behind Causeway Bay by hundreds of performers.
- Wednesday 15 September: the festival itself. Families eat together, then go out to look at the moon in parks and on beaches.
- Around the festival: lantern carnivals at Victoria Park and other large parks, by custom.
- Thursday 16 September: the public holiday, the day after the festival, rather than the festival itself.
#The Storm Record
September has a reputation, and the Observatory’s record shows it is earned.
Six storms have required the No. 10 hurricane signal since 2012: Vicente in July 2012, Hato in August 2017, Mangkhut on 16 September 2018, Saola on 1 September 2023, Wipha in July 2025 and Ragasa on 24 September 2025. Half of those came in September. Before Vicente, the signal had been needed only once since 1983, for York in 1999, so this is a recent run.
None of that makes a September trip reckless. Over 1991 to 2020 a No. 8 or higher averaged about two September days in three years, and the odds of one in any particular week are low. It does change how you should book. Take rates you can cancel, avoid a tight connection on the way home, and if a storm is forecast, buy food early and stay put. Mangkhut in particular left fallen trees across the city for days afterwards, so outdoor plans can stay disrupted once the signal has come down.
The good news is what happens between storms. The sea is warm, the racing season is back at Happy Valley, and the humidity starts to ease in the last week. Hotels hold their summer rates until the autumn fairs begin.
Mid-Autumn sits in the middle of it, on Wednesday 15 September in 2027. See our Mid-Autumn page and the Fire Dragon page for how to spend it.
#What to Do in Hong Kong in September
Look for a clear morning for anything high, and keep the evenings for the festival.
Solo Travellers
See the Fire Dragon on its first or third night, when the crowds are a little smaller, then eat in Tai Hang's small cafés. On a clear day, try Dragon's Back early, with extra water for the heat.
Couples
Take a picnic and a lantern to Repulse Bay or a harbour-front park on festival night, as local families do, and watch the moon rise. Book a Peak restaurant only if the forecast is clear.
Families
Children carry lanterns on Mid-Autumn night, and the carnival at Victoria Park is the natural place to take them. School is back, so Ocean Park and Hong Kong Disneyland are quiet on weekdays.
Groups
Happy Valley's Wednesday races return for the new season, around the start of the month. A night at the rail, HK$10 or so to enter, is one of the city's great cheap outings.
#Getting Around
- To Tai Hang: walk from Causeway Bay. The streets are closed and crowded.
- Airport Express: HK$120 to Hong Kong Station and HK$105 to Kowloon on Octopus.
- MTR: HK$10.60 from Central to Tsim Sha Tsui on Octopus.
- Star Ferry: HK$5 upstairs on weekdays, and it is a fine place to see a full moon.
- Trams: HK$3.30 flat, stopping along Causeway Road.
#Budget & Costs
| Travel style | Per day | What it covers |
|---|---|---|
| Budget | HK$800–1,300 | A hostel or guesthouse, cha chaan teng meals, the MTR |
| Mid-range | HK$1,900–3,000 | A central hotel, restaurants, a museum |
| Luxury | HK$5,200+ | Harbour-view rooms, a hotel mooncake or two |
What things cost:
| What | Price |
|---|---|
| Airport Express to Hong Kong Station, Octopus | HK$120 |
| MTR, Central to Tsim Sha Tsui | HK$10.60 |
| Happy Valley public enclosure | About HK$10 |
| Fire Dragon and lantern carnivals | Free |
| Tram, any distance | HK$3.30 |
Where the money actually goes:
- Mooncakes can be surprisingly expensive: a good box costs far more than a meal.
- Rooms are still at summer rates until the last week.
- Hotels add a 3% tax and usually a 10% service charge, so check a rate includes both.
#Food & Dining
Mooncakes are the month's food, sold in lotus-paste, egg-yolk and custard forms, and given away by the boxful. Pomelo and taro turn up at the festival table. Late in the month the first hairy crabs appear in some Shanghainese restaurants, though most people wait until October. Otherwise it is still a month for cold drinks and rice noodles.
#Nightlife
The rooftops start to come back at the end of the month. Lan Kwai Fong and Knutsford Terrace stay lively, and Tai Hang's small bars are a neighbourhood pleasure after the Fire Dragon. Racing nights at Happy Valley bring a young crowd.
#Shopping
Lanterns and mooncakes fill the shops of Sheung Wan and the old streets of Wan Chai. Hotel mooncakes come in elaborate boxes and sell out early. There is no sales tax.
#Culture & Etiquette
Giving mooncakes is a social ritual, so if you are given a box, accept it with both hands. Paper lanterns and open flames on beaches are controlled, and wax play is banned in many parks; follow the signs. On the Fire Dragon route, watch out for sparks, and stay back from the incense.
#Essential Local Phrases
| Cantonese | Meaning | When to use |
|---|---|---|
| 中秋節快樂 (jung chau jit faai lok) | Happy Mid-Autumn Festival | On 15 September |
| 月餅 (yuet beng) | Mooncake | In every bakery |
| 燈籠 (dang lung) | Lantern | At Victoria Park |
| 舞火龍 (mou fo lung) | Fire Dragon dance | In Tai Hang |
| 打風 (da fung) | "A typhoon is hitting" | Possibly |
| 唔該 (m goi) | Please, or thanks for a service | All day |
#Packing List
- Light clothes, as for summer
- A compact umbrella
- A rain jacket for storm days
- Comfortable closed shoes for the Fire Dragon crowd
- Sun cream and a hat
- Swimwear
- Mosquito repellent
- A power bank
#Backup Plans
- A No. 8: stay near your hotel, buy food early, and check any festival programme after it drops.
- A wet day: M+ at HK$190 and the Hong Kong Palace Museum from HK$70.
- Festival crowds: watch the moon from a quieter beach or an island instead.
#Safety & Health
Dial 999 in an emergency. Heat and typhoons are still the main risks, with crowds at the Fire Dragon a close third: follow the marshals, and hold on to children. Carrying a vape in a public place is also an offence, with a HK$3,000 fixed penalty. National security laws here are strict and cover visitors too: see First Time in Hong Kong.
