Singapore maintains good air quality through strict environmental regulations, but seasonal haze from regional fires can cause sharp pollution spikes. The tropical climate means year-round warmth and humidity, which can intensify ozone formation. Runners should monitor conditions closely during the haze season from June to October.

Try it freeSingapore typically sees AQI values between 20 and 50 outside of haze season. During haze events (typically August-October), readings can spike above 200, prompting health advisories.
December through June offers the cleanest air. Early morning runs beat both the heat and haze. Gardens by the Bay and the Southern Ridges trail offer excellent routes. Monitor the NEA PSI index during haze season.
Local sources include vehicle emissions, industrial activity, and shipping in one of the world’s busiest ports. The most significant pollution events come from transboundary haze caused by agricultural burning and peatland fires in Indonesia, typically between August and October.
The Southern Ridges trail, MacRitchie Reservoir, and Gardens by the Bay offer excellent running with cleaner air. East Coast Park benefits from sea breezes. The Green Corridor (former Keretapi Tanah Melayu railway) provides a car-free route through greenery. During haze events, indoor tracks at sports complexes are a good alternative.
The Southwest Monsoon season (August–October) brings the highest risk of transboundary haze from Indonesian fires. When haze strikes, the PSI can exceed 200 for days. Outside of haze season, Singapore generally enjoys good air quality year-round due to consistent tropical winds.
