The Health Promotion Board (HPB) has cancelled all its outdoor activities scheduled for Monday, 12 October 2026, because of the haze. Its indoor activities will proceed.
In a Facebook announcement on the evening of 11 October, cited by 8world, HPB said it was taking this precaution because air quality was forecast to remain unhealthy over the following 24 hours.
Check Healthy 365 Before Heading Out
HPB advised participants to check the Healthy 365 app for updated activity arrangements or ask the organisers at the venue, according to 8world.
The report also noted that HPB had posted notices on 9 and 10 October cancelling the following day’s outdoor activities. That means its outdoor sessions have been affected across three consecutive days, from 10 to 12 October.
For booking updates, HPB’s Help Centre advises users to enable push notifications, check their email and look at the Booked tab on the Healthy 365 dashboard. Participants can find organisers’ contact details in the information for their session.
Haze Forecast to Persist
In its 11 October evening advisory, reported by CNA, the National Environment Agency (NEA) forecast that the 24-hour Pollutant Standards Index, or PSI, would stay in the unhealthy band over the next 24 hours.
NEA said smoke from southern Sumatra and West Kalimantan was moving towards Singapore, with winds potentially bringing more haze here.
Although showers were forecast for Singapore and parts of the surrounding region, dry weather was expected to persist in parts of southern Sumatra and Kalimantan.
What to Know About Outdoor Exercise
Under HPB’s standing haze policy, outdoor activities can be relocated indoors where possible or cancelled when the 24-hour PSI reaches the unhealthy band of 101 to 200, or hourly PM2.5 reaches the elevated band of 56 to 150 micrograms per cubic metre. PM2.5 refers to fine airborne particles.
HealthHub’s guidance distinguishes between the readings: hourly PM2.5 helps people decide about an immediate outdoor activity, while the 24-hour PSI forecast helps with planning the next day.
When PSI is unhealthy, healthy people should cut back on lengthy or strenuous outdoor exercise. Older people, pregnant women and children should keep such exertion to a minimum, while people with chronic heart or lung disease should avoid it.
