Haze pushes Singapore air to unhealthy levels; Johor schools to reopen

2026-10-25 · Climate · Singapore · Malaysia

Air quality across Singapore turned unhealthy as regional haze from Sumatran fires spread, with 24-hour PSI readings of 104 to 140 at 7am and hourly PM2.5 readings of 44 to 62. CNA reported indoor air can test worse than outdoors, and some expired masks still filter particles. In Malaysia, Johor's education department said all schools will reopen on Oct 26 as conditions improve, while other areas remain affected. In Indonesia's Kalimantan, students protested, demanding the government do more. ASEAN has struggled for decades to stop the fires, with prevention still hinging on Jakarta's willingness to act.

Why it matters：A recurring transboundary pollution crisis is again disrupting health, schooling and travel across Southeast Asia, exposing how little regional mechanisms have achieved.
