Top 10 Things to Do in Singapore When the Haze Hits
The air has a campfire edge and your eyes are stinging — here is what the NEA numbers actually mean, and ten places worth your afternoon with the doors shut.
You smell it before you see it: that burnt edge in the lift lobby, the skyline going soft somewhere around the fourth tower. On 14 September the 24-hour PSI sat in the unhealthy range across all five regions, at 128 in the east and west, 111 in the south and 104 in the north. That is the number to learn. NEA bands the 24-hour PSI as 0-50 Good, 51-100 Moderate, 101-200 Unhealthy, 201-300 Very Unhealthy and above 300 Hazardous, and it is the index the national health advisory is written against, right down to decisions about whether schools stay open. For anything you are about to do in the next hour, use the 1-hour PM2.5 instead, because it moves first - NEA groups it as normal at 0-55 micrograms per cubic metre, elevated at 56-150, high at 151-250 and very high above 251. Both sit on NEA's haze site, and MOH and NEA put out a personal guide to the 1-hour reading in July for exactly this kind of week.
MOH treats a PSI of 101 and above as unhealthy, and says the health impact depends on your own health status, the PSI level, and how long and how hard the exposure is. The people who should act first are children, the elderly, pregnant women and anyone with chronic heart or lung disease, asthma included. Stay indoors with air-conditioning or a purifier running and the windows shut. An N95 is not needed indoors, and not needed for the short hop from bus stop to mall; it earns its place only if you will be outside for several hours, and only if it actually fits your face, which a surgical mask will never do for PM2.5. Elderly people, pregnant women and anyone with severe heart or lung problems should ask a doctor before relying on one. Drink water. A dry or scratchy throat usually settles once you are out of the air, but symptoms that persist or worsen or a flare of an existing heart or lung condition - mean a doctor, not a wait-and-see. Two things exist in the background and are worth knowing: MOH can activate the Haze Subsidy Scheme at polyclinics and Public Health Preparedness Clinics, which last ran in 2015 at $5 for Pioneers and $10 for other eligible Singaporeans, and clinic operators said this week that MOH has not alerted them about it in 2026; and MOM can issue stop-work orders under the Workplace Safety and Health Act where employers have not mitigated haze risk for outdoor workers.
So, what to drop. Above a 24-hour PSI of 100, cut the outdoor sport - the East Coast run, the Saturday football, the Botanic Gardens picnic — and shorten anything prolonged or strenuous outdoors, with children, the elderly and people with heart or lung disease minimising outdoor exertion at that point. Between 56 and 150 on the 1-hour PM2.5, healthy adults should reduce strenuous outdoor activity and vulnerable people should avoid it outright. From 201 to 300 on the 24-hour PSI, avoid prolonged outdoor activity and move anything planned indoors. Which leaves this list. It is ranked by how little outdoor air the outing costs you door to door, then by value, then by whether you can simply turn up without booking. Free things climb when they are also easy to reach. The entry at the bottom is genuinely good and costs you a walk, which is why it is at the bottom.
ArtScience Museum
6 Bayfront Avenue, Marina Bay Sands, Marina Bay · Art and science museum · Ticketed, with Singapore-resident and concession rates; the museum advises coming in the morning, when traffic is lighter
Photo: https://www.singapore-tickets.com/art-science-museum-tickets/about/ source
The lotus-shaped one, and on a bad-air day the best argument for staying underground the whole way — you arrive at Bayfront and never meet the outside. Concession pricing covers seniors 60 and over, students, children aged two to twelve, persons with disabilities and NSFs, and residents get their own rate on production of an IC, so bring it. The museum itself says to come in the morning because capacity is limited and queues build later, which is advice worth taking when the alternative is standing outside. Check the last-entry time when you book rather than turning up at dusk.
National Gallery Singapore
1 St Andrew's Road, Civic District · National art museum · Free for Singapore citizens and PRs; daily 10am–7pm, admission ends 6.30pm
Photo: https://www.klook.com/en-IN/activity/1256-national-gallery-singapore/ · https://www.klook.com/en-IN/activity/1256-national-gallery-singapore/ source
Cold marble, high ceilings, and a building that swallows three hours without you noticing — the Gallery's own estimate for a visit, and about right. Free for citizens and PRs, which makes it the single best-value place to park yourself for an afternoon in bad air. Note that the UOB Southeast Asia Gallery is closed until late 2027, with works from the National Collection shown across the rest of the building instead, so go for the temporary shows and the rooms you usually skip. Ticket sales and admission stop half an hour before closing.
Canopy Park
Level 5, Jewel Changi Airport, 78 Airport Boulevard, Changi · Indoor gardens and play attraction · Ticketed, Mon–Thu 10am–9pm, Fri–Sun, eves and public holidays 10am–10pm; last admission 30 minutes be
The genius of Jewel on a haze day is the arrival: the train lets you out inside the building and the outdoors never gets a turn. Up top it is mazes, slides and foggy bowls under glass, with bundle deals if you want to string several attractions together rather than pay for each. The Walking Net is closed for maintenance, so if that was the whole reason for the trip, rethink the plan. Best with children who have been bouncing off the walls at home for two days.
Cloud Forest
Gardens by the Bay, 18 Marina Gardens Drive, Marina Bay · Cooled glasshouse conservatory · Ticketed with Singapore Resident rates; Jurassic World: The Experience inside carries an additional $14 entry
Photo: https://www.klook.com/activity/162276-gardens-by-the-bay-ticket-with-hotel-pickup/?dd_referrer=https%3A%2F%2Fwww.google.com%2F source
Cool, misted, enclosed and about fifteen degrees more forgiving than the street — the conservatory is doing on purpose what your flat is doing badly. Jurassic World: The Experience is installed inside, and the Gardens charges an extra $14 on top of conservatory admission for it, so decide at the counter whether you want dinosaurs with your mountain. Residents pay a lower rate and may be asked to prove it, so carry ID. The last stretch from Bayfront is open air, which is a few minutes of exposure worth masking for.
Flower Dome
Gardens by the Bay, 18 Marina Gardens Drive, Marina Bay · Cooled glasshouse conservatory · Children 12 and under free for Singapore residents from 5 to 27 September during Lilytopia; adults pay standa

Drier and brighter than its neighbour, and this month it is full of lilies, with an Egypt-themed display running through the Mediterranean plantings. Until 27 September, children aged twelve and under go free if they are Singapore residents, which turns a family outing into one adult ticket. Organised group visits are excluded from the offer, so this is for the two-parents-and-a-pram version of the day. Pair it with the Cloud Forest if you want to make the trip out to Marina Bay earn itself.
National Museum of Singapore
93 Stamford Road, Civic District · History museum · Free permanent galleries for Singapore citizens, PRs and children under six; daily 10am–7pm
Photo: https://www.nationalmuseum.nhb.gov.sg/plan-your-visit/visitor-information/upgrading source
Free for locals, open until seven, and cool enough that people quietly use it as a weekday refuge — which is the whole point this week. Concession fees apply to specific groups beyond the free-entry categories, so check before you queue. Galleries here rotate through restoration, so look at what is actually open on the day rather than arriving with one exhibit in mind. Ten minutes from the Gallery if you want to do both and never go further than the Civic District.
Singapore Oceanarium
8 Sentosa Gateway, Resorts World Sentosa, Sentosa Island · Aquarium · Tickets from S$43, free for children under four
Photo: https://www.singapore-tickets.com/resorts-world-sentosa/singapore-oceanarium/ source
Three times the size of the old S.E.A. Aquarium, with more than 100,000 animals across 22 zones — meaning several hours indoors without repeating yourself, which is the metric that matters right now. Tickets start at S$43 and under-fours go free, so it is the priciest entry here and the one that most reliably fills a whole day. Take the Sentosa Express rather than walking the boardwalk across; the boardwalk is lovely and entirely the wrong idea at PSI 120. Book online before you leave the house.
Central Public Library
100 Victoria Street, National Library Building, Bras Basah–Bugis · Public library · Free entry, no booking; check current hours on nlb.gov.sg

Free, air-conditioned, and nobody will ask why you have been sitting there since eleven. The library reopened in January 2024 after its first full overhaul, with a local emphasis on Singapore culture and literature and the Children's Biodiversity Library by S.E.A. Aquarium anchoring the kids' section. Bugis, City Hall and Bras Basah are all close, so pick whichever gives you the shortest stretch of open pavement. The most honest entry on this list: it costs nothing and does the job.
Yunomori Onsen & Spa
1 Stadium Place, #02-17/18 Kallang Wave Mall, Kallang · Japanese onsen and Thai spa · Day pass covers all-day access to the baths, steam room, towels and a yukata; sauna in the male onsen area only
Photo: https://www.klook.com/en-IN/activity/144913-yunomori-onsen-and-spa-at-sathorn-10-experience-in-bangkok/ source
Hot mineral water, a yukata and a lounge you are not expected to leave — the correct response to a day when going outside is the problem. The day pass runs all day and includes towels, amenities and lounge access, with the sauna sitting in the male onsen area only, which is worth knowing before you pay. Add a massage if you are making an afternoon of it. It is inside a mall, so the door-to-door exposure is small and the payoff is large.
Science Centre Singapore
15 Science Centre Road, Jurong East · Science museum · Ticketed; open 10am–5pm

Last, and only because of the approach — the walk from Jurong East MRT is real outdoor time, so take a cab to the door at anything above 100 and the whole calculation changes. Inside, it is the same reliably hands-on afternoon it has always been, closing at five, which means an early start. If Snow City is part of the plan, buy those tickets separately and in advance, on Snow City's own site, before you go. Good with children old enough to read the labels, less so with toddlers.
