Haze returned to Singapore on 24 October with 24-hour PSI readings between 108 and 154 at 9 p.m., prompting NEA to forecast Sunday levels in the 80–130 band while hourly PM2.5 concentrations ranged from 64 to 96 micrograms per cubic metre.

Air quality and forecasts

Western estates recorded the highest PSI prints, matching the pattern seen in prior transboundary smoke episodes. NEA said wind shifts could ease particulate loads by Sunday afternoon, but planners should check hourly updates before scheduling outdoor sports.

Health guidance

Ministry of Health guidance repeated on NEA channels tells vulnerable groups—elderly residents, pregnant women, children and people with chronic lung or heart conditions—to reduce strenuous outdoor activity and seek care if breathing worsens. Healthy adults should limit prolonged exertion when PSI enters the unhealthy range.

Heartland general practitioners and polyclinics told InfoHandle Network they are seeing more cough, throat irritation and asthma flare-ups consistent with prior haze weeks, though national case statistics lag real-time clinic traffic. Doctors advise carrying rescue inhalers and using N95 masks when commuting in open areas.

Schools and workplaces

Principals monitored PE lessons on Friday evening announcements, with several schools moving drills indoors if PSI stayed above 100 on Sunday morning. Employers with outdoor crews distributed hydration breaks and respirators for landscaping teams.

Household steps

Residents closed windows and ran air purifiers on auto mode. NEA’s MyENV app pushes thresholds when PM2.5 spikes; subscribing saves manual website checks. Those with chronic conditions should refill prescriptions early in case clinics fill appointment slots.

Until regional burning eases, PSI in the low hundreds means haze plans stay active even if skies look clearer at midday.

Clinic floor reports

Doctors at heartland clinics told InfoHandle Network they are documenting more upper-respiratory visits than a typical October week, consistent with NEA’s health guidance for when 24-hour PSI crosses 100. MOH has not issued a national alert, but individual practices are extending evening slots for nebuliser treatments.

Pharmacies near MRT stations restocked N95 masks by Friday night as commuters shared photos of hazy sunsets online. NEA’s Sunday forecast of PSI 80–130 suggests improvement, yet hourly PM2.5 swings mean schools should keep indoor contingency plans ready for Monday assemblies.

MOH’s public messaging reminds residents that PSI above 100 warrants reducing prolonged outdoor exertion even if skies look deceptively bright at noon. Employers with delivery riders should rotate routes toward covered walkways where possible and provide masks when hourly PM2.5 readings stay in the 64–96 band NEA reported at 9 p.m.

National Parks Board closed no major trails on 24 October, but hikers with asthma were urged to pick shorter loops and carry rescue medication, matching guidance on the haze microsite.
