At a Glance
Compared to this destination's peak season September is a moderate month now that the Grand Prix has moved to October (8–10 October 2027); the Food Festival and the Mid-Autumn Festival on 15 September 2027 bring the crowds to Chinatown and the food venues. In a dry El Niño year, check the haze forecast.

#Weather in Singapore in September
Singapore in September averages 25–32°C (77–90°F) with around 14 days of rain, and crowds are medium.
| Measure | September in Singapore |
|---|---|
| Daytime high | About 32°C / 90°F |
| Overnight low | About 25°C / 77°F |
| Rain | About 170mm across 14 wet days |
| Humidity | 80–90% |
| Rain pattern | Bright mornings, then short heavy afternoon thunderstorms |
| Haze | September and October are the usual risk months in dry El Niño years |
Figures are Meteorological Service Singapore 1991–2020 normals. September sits at the tail of the Southwest Monsoon.
What that actually means for your trip:
- Two things shape the month, and neither is the weather. One is food: the Singapore Food Festival now runs in September, and the Mid-Autumn Festival follows on Wednesday 15 September 2027. The other is the possibility of haze, which has its own section below.
- The F1 night race is not in September any more. The 2027 Singapore Grand Prix is on 8–10 October; a lot of published advice has not caught up.
- Build the day around the tropical rhythm rather than trying to beat it: mornings out, afternoons in, evenings out again.
- Watch the haze forecast before booking. In most years the air is fine; in dry El Niño years, smoke from fires in Indonesia can arrive in September.
Should you come in September? Come for the food. The weather is straightforward, the crowds are moderate now that the Grand Prix has moved, and the mooncake season is in full swing. Keep the itinerary flexible for a possible hazy spell, and you will have one of the best-value months of the Singapore year.
#Haze: The September Wildcard
In some years, smoke from land and forest fires in Sumatra and Kalimantan drifts over Singapore in the late dry season, turning the sky flat and white. The bad years, 1997, 2015 and 2019 among them, came with El Niño, and September and October are the usual peak months. In most years nothing happens at all.
The Singapore Institute of International Affairs publishes a Haze Outlook each year rating the regional risk; in 2026 it rated the risk Red, its highest level. Check the current year's outlook when you book, and the live readings when you travel.
Singapore publishes hourly readings of the PSI (Pollutant Standards Index) at haze.gov.sg:
- 0–50 Good and 51–100 Moderate: normal life.
- 101–200 Unhealthy: reduce prolonged outdoor exertion.
- 201–300 Very Unhealthy: avoid outdoor activity.
- Above 300 Hazardous: stay indoors.
The consolation is real: Singapore is one of the best-equipped cities on earth to wait out bad air. The malls, the museums, the Gardens by the Bay conservatories and Jewel are air-conditioned and linked by covered walkways and the MRT. A hazy week is an eating-and-museums week, which in September is no hardship.
#What to Do in Singapore in September
The Singapore Food Festival
The Singapore Food Festival used to run in July. It now runs in September: the 2026 edition was 4 to 24 September, at Dempsey, in Chinatown and at pop-ups across the island. A lot of published advice still calls it a July event.
The programme mixes large ticketed Signature Events with hawker showcases, chef collaborations and heritage-recipe sessions on the Peranakan, Malay, Tamil and Hainanese roots of Singaporean food. Check the 2027 dates and line-up on VisitSingapore.
Mid-Autumn Festival: Wednesday 15 September 2027
The Mid-Autumn Festival, the mooncake-and-lantern festival, falls on the fifteenth day of the eighth lunar month, which is Wednesday 15 September 2027, ten days earlier than in 2026.
Chinatown is lit with lantern displays for several weeks around it, free, and Gardens by the Bay usually adds its own lantern installations; check the 2027 dates for each.
Mooncakes arrive in every bakery and hotel lobby from August. The traditional ones are baked and dense, filled with lotus-seed paste around a salted egg yolk that stands for the full moon; the modern snowskin ones are chilled and soft, filled with anything from champagne truffle to durian.
The Grand Prix is in October now
The Formula 1 Singapore Grand Prix moved from September to October, and the 2027 race is on 8–10 October at the Marina Bay Street Circuit. For more than a decade the night race was September in Singapore, and a great deal of travel writing still says so.
What September is not good for
A clear-sky, outdoor-heavy trip in a haze year. It is also hot and humid, with no festival of the outdoors. As an eating month, a museum month and an evening month, it is excellent; as a beach-and-hiking month, February is a far safer bet.
#Getting Around
Changi Airport connects to City Hall on the East-West MRT line in around 30 minutes, entirely under cover.
Taxis and Grab to Marina Bay run about S$25–45.
Adult card fares on the MRT and buses ran from about S$1.28 for a short hop to about S$2.57 for a long cross-island journey after the December 2025 fare review, and the Public Transport Council reviews them every year, so expect small changes. Use an EZ-Link card, or tap a contactless Visa or Mastercard through SimplyGo, which charges the same fares with nothing to buy.
The Marina Bay road closures that older guides warn about are an October problem now, with the Grand Prix on 8–10 October 2027. September traffic is ordinary.
#Budget & Costs
| Travel style | Per day | What it covers |
|---|---|---|
| Budget | S$70–110 | Hostel dorm, hawker meals, MRT everywhere |
| Mid-range | S$140–220 | 3- or 4-star hotel |
| Comfortable | S$280–450 | 4- or 5-star hotel, restaurants, paid sights |
| Luxury | S$700+ | Marina Bay Sands, Raffles or the Fullerton |
September has become one of the better-value months: for more than a decade the Grand Prix made mid-September the most expensive time of the Singapore year, and the race took the price spike with it to October.
Costs worth knowing:
| What | Price |
|---|---|
| Hawker meal | About S$5–10 |
| Single bakery mooncake | A few dollars |
| Boxed hotel mooncake set | Many times that |
| Taxi, Changi to downtown | About S$25–45 |
| MRT single ride | From about S$1.28 |
- The Grand Prix premium has gone from September. Older guides still price mid-September as the year's peak.
- The Mid-Autumn programme is largely free, and so is much of the Food Festival's hawker programming.
- Haze is the one contingency. A box of N95 masks is cheap insurance.
#Food & Dining
September is Singapore's food month.
Singapore's hawker culture was inscribed on UNESCO's list of Intangible Cultural Heritage in 2020, recognising the hawker centre, where a rojak seller and a banker eat the same cheap lunch at the same plastic table, as a cultural achievement worth protecting. It needs protecting: many hawkers are ageing, and their children often don't want the stalls.
Singapore is where a hawker stall first won a Michelin star, in 2016, for soya-sauce chicken rice at a couple of dollars a plate, and Hill Street Tai Hwa Pork Noodle has held a star too.
Use the month to work through the canon.
Chicken rice at Tian Tian in Maxwell Food Centre. Laksa at 328 Katong, eaten with a spoon. Bak chor mee at Hill Street Tai Hwa, where the queue is long and worth it. Bak kut teh, the peppery pork-rib soup, at Founder in Balestier.
Chilli crab at Jumbo or Long Beach.
And satay on Boon Tat Street outside Lau Pa Sat from about 7pm, when the road closes and the grills come out.
Old Airport Road Food Centre is the hawker hall Singaporeans send you to; Tekka Centre in Little India is the one for biryani and roti prata.
At the top end, Odette, Zén, Burnt Ends and Candlenut, the first Peranakan restaurant to hold a Michelin star, are the names, and September, without the Grand Prix, is an easier month to get into them.
#Nightlife
Singapore's bar scene is world class and, in a month this humid and possibly hazy, mostly indoors.
Atlas in Bencoolen, with its art-deco gin tower, is the most photographed bar in the country.
Manhattan at the Regent Singapore, Jigger & Pony and 28 HongKong Street, the original speakeasy, are regulars on the regional best-bar lists.
For height, CÉ LA VI and LAVO sit on the Marina Bay Sands rooftop, though a rooftop is the wrong booking on a high-PSI evening.
1-Altitude at One Raffles Place is closed for redevelopment, despite still appearing on rooftop-bar lists.
#Shopping
Chinatown is the September destination, for the Mid-Autumn light-up and the mooncake and lantern stalls.
Orchard Road's malls (ION Orchard, Paragon, Ngee Ann City) are linked underground and air-conditioned, which matters in a hazy month.
Bugis Street is the cheap and cheerful end, Haji Lane in Kampong Glam has the independents, and Mustafa Centre in Little India is open around the clock.
Visitors can reclaim the 9% GST on qualifying purchases at Changi.
#Culture & Etiquette
- Mooncakes are a gift. Receive the box with both hands; at home they are cut into wedges and shared.
- Temples are welcoming. Remove shoes and cover shoulders and knees.
- Singlish is affectionate, not broken English. Enjoy it; don't imitate it.
- "Choping": a packet of tissues on a hawker table means it is reserved. Don't move it.
- No eating or drinking on the MRT, and no littering; the fines are enforced.
- No tipping: a 10% service charge and 9% GST are added in restaurants.
- Vaping is illegal, with heavy fines, and pods laced with etomidate are treated under drug law.
Drug laws are among the harshest anywhere.
#Essential Local Phrases
Singapore has four official languages plus Singlish. You'll get by in English everywhere, but a few local words help with menus and hawker stalls.
| What you want to say | What you'll hear in Singapore |
|---|---|
| Yes / OK | Can lah (Singlish) |
| No / Cannot do | Cannot (Singlish) |
| Delicious | Shiok (Singlish) |
| To eat / Let's eat | Makan (Malay) |
| Iced coffee | Kopi peng (Hokkien) |
| Spicy | Pedas (Malay) |
| Thank you | Terima kasih (Malay) / Xie xie (Mandarin) |
| Reserving a hawker table | Chope (Singlish) |
#Packing List
- Light, breathable cotton or linen
- N95 (or KN95 / FFP2) masks in case of haze, and an inhaler if you use one
- A compact umbrella, which doubles as shade
- Comfortable walking shoes and sandals for the evening
- High-factor sunscreen and sunglasses
- A light layer for cold air-conditioning
- Insect repellent, a UK-style three-pin adapter and a refillable water bottle
- Eye drops, if the PSI climbs
#Backup Plans (Rainy Days and Hazy Days)
September needs one plan that covers both: get indoors well.
The connected complexes are enormous.
Marina Square, Suntec City, ION Orchard and VivoCity all have restaurants, cinemas and direct MRT access.
Jewel Changi Airport, with its indoor waterfall, is worth half a day even if you are not flying.
The museum circuit is the strongest option: the National Gallery Singapore, the ArtScience Museum, the Asian Civilisations Museum and the Peranakan Museum, all a short covered walk from City Hall MRT.
The Cloud Forest and Flower Dome at Gardens by the Bay are climate-controlled.
The Mandai wildlife parks are largely open-air, the one major attraction to postpone if the PSI climbs above 150.
#Safety & Health
Singapore is one of the safest cities in the world. September's risks are environmental.
Haze: check haze.gov.sg each morning rather than trusting the look of the sky, because haze and ordinary humidity can look alike. Above a PSI of 100, cut back on prolonged outdoor exertion; above 200, stay in.
Heat and humidity catch people out: drink more than feels necessary and treat the middle of the day as indoor time.
Lightning is a real hazard, among the highest strike densities on earth, and outdoor attractions pause during warnings.
Dengue is a year-round concern; use repellent, especially by day.
Tap water is safe. Healthcare is excellent and expensive, so travel insurance is recommended.
Emergency: 999 for police, 995 for ambulance and fire.

Frequently Asked Questions
Is the Formula 1 Grand Prix in September?
Not any more. The Formula 1 Singapore Grand Prix moved to October, and the 2027 race is on 8 to 10 October at the Marina Bay Street Circuit. For more than a decade it was a September fixture, and much published advice still says so. The road closures, concerts and high hotel prices moved with it, which has made September calmer and cheaper.
When is the Singapore Food Festival?
It now runs in September; the 2026 edition was 4 to 24 September, at Dempsey, in Chinatown and at pop-ups across the island. It used to be a July event, and a lot of advice still says so. Check VisitSingapore for the 2027 dates and programme, and build your visit around the hawker events rather than the most expensive ticketed ones.
Will there be haze in Singapore in September?
Possibly, in a dry El Niño year. Smoke from land fires in Sumatra and Kalimantan can reach Singapore in September and October, as it did badly in 1997, 2015 and 2019, but in most years nothing happens. Check the regional Haze Outlook when you book and the live PSI readings at haze.gov.sg when you travel, and carry N95 masks.
When is Mid-Autumn Festival in Singapore in 2027?
Mid-Autumn Festival falls on the fifteenth day of the eighth lunar month, which is Wednesday 15 September 2027, ten days earlier than in 2026. Chinatown is lit with lanterns for several weeks around it, and mooncakes are sold everywhere from August. A single bakery mooncake costs a few dollars; boxed hotel sets are gifts.
What’s the weather like in Singapore in September?
Singapore in September typically sees temperatures of 25–32°C with around 14 days of rain across the period. Pack light, breathable layers and strong sun protection — days get genuinely hot.
How much does it cost to visit Singapore in September?
Budget-conscious travellers can expect daily costs of $60–1,200+, covering accommodation, food, and local transport. Flexible dates can save up to 20% compared with peak-week rates.
