(Updated on 30 January 2012)

Northeast Monsoon conditions are expected to prevail over the region till March 2012, with low level winds blowing predominantly from the northeast or northwest. The region is currently in the dry phase of the Northeast Monsoon season. While sporadic increases in hotspot activities can be experienced during brief periods of drier weather conditions, the hotspot situation over Sumatra is likely to remain subdued. Singapore is thus unlikely to be affected by significant transboundary haze. Singapore may however experience brief slight haziness from time to time, especially in the morning. This is due to the accumulation of particulate matter under light wind conditions and/ or mist, and would usually clear later in the day.

The PSI will be updated on this website daily at 4pm.
