The likelihood of haze affecting Singapore remains low on Tuesday, with prevailing winds and showers helping clear the air, the National Environment Agency reports.
- Showers expected to reduce haze on Tuesday
- PSI forecast remains in good to moderate range
- Vulnerable groups advised to monitor hourly PM2.5 readings
What happened
The National Environment Agency (NEA) issued an advisory stating that the likelihood of smoke haze affecting Singapore is low on Tuesday, October 27. Prevailing winds are expected to come from the northeast or southeast, combined with showers across Singapore and its surrounding areas, which help suppress haze formation.
Air quality measurements support this outlook, with the 24-hour Pollutant Standards Index forecast ranging between 60 and 90, classified within the good to moderate range. Recent PSI readings overnight on Monday stayed within these bands, with the highest pollution levels detected in the western part of the island, but still not reaching unhealthy levels.
Why it feels good
The approaching showers bring welcome relief from transboundary haze which sometimes drifts from regions such as Kalimantan and Peninsular Malaysia. Rainfall reduces airborne particulates, helping clear the skies and providing cleaner air to breathe.
The steady improvement in air quality means residents can continue outdoor and strenuous activities with minimal worry. While moderate haze is still present in parts of nearby Indonesian regions, Singapore’s local conditions including variable winds and rainfall mitigate the impact, keeping health risks low for the majority.
What to enjoy or watch next
Residents should stay informed by checking the latest 24-hour PSI forecasts and hourly PM2.5 readings, especially if they belong to vulnerable groups such as children, elderly, pregnant women, or those with respiratory or heart conditions. This helps tailor outdoor activity decisions on an hourly basis according to air quality changes.
Looking ahead to Wednesday and Thursday, winds are expected to become variable and showers will likely persist, potentially maintaining the suppression of haze. However, areas that remain dry could still experience elevated haze levels. Continued monitoring and timely advisories will ensure that Singaporeans can plan safely and enjoy their outdoor time.
