The recent hazy conditions in Singapore are due to accumulated particle matter under light winds, according to the National Environment Agency (NEA).

NEA, which issues daily updates on the haze situation, first warned that Singapore may experience "slightly hazy conditions in the morning" on Tuesday last week.

Since then, haze-like conditions have been reported in certain areas.

Photos taken by The Straits Times on Wednesday evening from the Marina Bay area showed hazy skies.

According to NEA, however, the likelihood of the country being affected by transboundary haze remains low.

"There were eight hot spots detected in southern Sumatra, and no visible smoke plume or haze was observed," NEA said in its last update on Wednesday.

The hourly concentration readings for PM2.5 - tiny pollutant particles associated with haze - for the next 24 hours are expected to stay within the normal range.

As of 9am yesterday, the 24-hour Pollutant Standards Index was in the moderate range.
