Singapore in autumn, from September to November, is warm, humid and gets wetter each month. Daytime highs stay around 31°C to 32°C, nights sit near 24°C to 25°C, and humidity runs from 80% to over 90%. September is the driest of the three. By November, the rain picks up as the year-end monsoon approaches, and it becomes one of the wettest months of the year.
The weather won’t feel like autumn, but the calendar is full. Lanterns go up in Chinatown for the Mid-Autumn Festival in September, the Formula 1 night race takes over Marina Bay in October, and Little India lights up for Deepavali in late October or November. Time your trip around one of these and you’ll see the city at its busiest, though hotel prices near Marina Bay jump during race week.
Summary
Expect highs of 31°C to 32°C, nights around 24°C to 25°C and humidity of 80% or more.
September is the driest month. October brings more afternoon storms, and November is one of the wettest months of the year.

Haze from regional fires can affect air quality in September and October in some years.
Plan outdoor sightseeing for the morning, indoor visits for mid-afternoon, and go back out after the rain clears in the evening.
What is autumn like in Singapore?
Singapore sits about 1.3° north of the equator, so it’s warm and humid every month of the year. The weather service divides the year by monsoon periods rather than seasons, and September to November spans two of them.
September is the tail end of the Southwest Monsoon, usually one of the drier stretches of the year. October and November make up the Second Inter-Monsoon period, when winds are light and changeable, and strong daytime heating builds thunderclouds that tend to break in the afternoon or early evening. The Northeast Monsoon, Singapore’s wettest season, starts in December.
September
Daytime highs average about 31.6°C, with nights around 25°C. Singapore in September is the driest of the three autumn months, which makes it the most comfortable for walking tours and outdoor sightseeing. Mid-Autumn lantern walks in Chinatown usually fall in this month too.
Before you go, check the haze. In some years, smoke from forest fires in neighbouring countries drifts over Singapore between August and October, and the NEA website or the myENV app shows the current air quality.
October
Highs stay around 31.8°C and nights around 25°C. Thunderstorms become more frequent, usually building in the afternoon and lasting 30 to 90 minutes before clearing. Race week falls in early or mid October, which makes this the most expensive month for hotels near Marina Bay.
November
Singapore in November gets the most rain of the three months, roughly 250 mm, with rain on more than half the days. Highs drop slightly to around 31.2°C, and nights to about 24.6°C. Once race week and Deepavali are over, hotel prices usually come down.
The Formula 1 Singapore Grand Prix
Race dates and format
The 2026 race ran from 9 to 11 October and was Singapore’s first Sprint weekend, with a shorter Sprint race on Saturday alongside qualifying for the main Grand Prix.
The 2027 Grand Prix is scheduled for Sunday 10 October and goes back to the standard format: practice on Friday, qualifying on Saturday and the race on Sunday night. It runs after dark on the Marina Bay Street Circuit, a 19-turn track of just under 5 km through the city centre.
Choosing where to sit
The Pit Grandstand faces the start and finish line, pit lane and podium, so it’s the pick if you want the race start and the celebrations. Turn 1 is where drivers brake hard after the start, which makes it the best spot for overtakes on the opening lap. The Padang Grandstand sits close to the Padang Stage, handy if the concerts matter as much to you as the racing.
If the grandstands sell out, a Premier Walkabout ticket lets you move between all four zones of the circuit park. You won’t have a seat, but you can watch from several viewing areas and catch more of the concerts.
Concerts and food around the circuit
Every race ticket includes access to the Zone 4 stages, including the Padang Stage, on the day the ticket is valid. In 2026, The Killers played after qualifying on Saturday and Lana Del Rey closed Sunday, with Janet Jackson, Zara Larsson and Major Lazer Soundsystem also on the line-up. The 2027 acts haven’t been announced yet.
For food outside the circuit, Lau Pa Sat’s satay street in the CBD is a short walk from the track, and Maxwell Food Centre is one MRT stop further out. Satay by the Bay at Gardens by the Bay is another option.
If you’d rather watch from above, LeVeL33 at Marina Bay Financial Centre and CÉ LA VI on top of Marina Bay Sands both overlook parts of the circuit. Prices go up on race nights, so book well ahead.
Autumn festivals and light-ups
The festival light-ups are some of the best things to do in Singapore in autumn, and you can see them without a ticket.
Mid-Autumn Festival (September)
The Mid-Autumn Festival falls on the 15th day of the eighth lunar month, which is 15 September in 2027. It isn’t a public holiday, so shops and offices stay open as usual.
In the weeks before, Chinatown hangs lanterns along Eu Tong Sen Street and New Bridge Road, and the evening street market sells lanterns and snacks. Gardens by the Bay usually holds its own lantern display around the Supertree Grove.
It’s also mooncake season. The traditional kind is baked with lotus seed paste and a salted egg yolk in the middle. Snowskin mooncakes are chilled, with a soft mochi-like crust, and come in flavours like durian and chocolate truffle. Pomelos, a traditional festival fruit, show up at stalls around the same time.
Deepavali (October or November)
Deepavali, the Hindu festival of lights, falls on 8 November in 2026 and 28 October in 2027. It’s a public holiday in Singapore.
Serangoon Road in Little India is lit with light arches for several weeks beforehand, and a festive bazaar near Campbell Lane sells sweets, flowers, clothes and decorations. Go in the evening, after the afternoon rain, when the lights reflect off the wet streets and photos come out best.
Planning your autumn trip
September has the best weather of the three months, plus the Mid-Autumn lanterns in Chinatown. Pick October if you’re coming for the Grand Prix, and book your hotel and race tickets early. November is the wettest month, but hotels are usually cheaper, and in 2026 you’ll catch Deepavali in Little India.
If you’re comparing Singapore tour packages for race week, check whether race tickets are included or need to be bought separately, since grandstand seats sell out months ahead. Couples looking at Singapore honeymoon packages should consider September, when the weather is drier and Chinatown’s lanterns make for easy evening walks.

September, October and November. Singapore doesn’t have four seasons, so the term just refers to the calendar months. Temperatures stay between about 24°C and 32°C all year.
Is autumn the best time to visit Singapore?
It’s a good time if you want festivals and the Grand Prix. For the least rain, September is the strongest of the three months. If you mainly want dry weather, February is usually drier than any autumn month.
Does it rain all day in Singapore in autumn?
Rarely. Most rain comes as afternoon or early-evening thunderstorms that last 30 to 90 minutes, and the sky often clears by evening. November has the most rainy days of the three months.
Are concerts included with F1 Singapore Grand Prix tickets?
Yes. Every race ticket includes access to the Zone 4 stages, including the Padang Stage, for the day the ticket is valid. The Wharf and Barge stages need a Zone 1 ticket.
