In short

The Meteorological Service Singapore reported that air quality remained within the moderate range on Thursday, with hourly PM2.5 levels staying mostly normal despite a brief morning spike in the west. Increased precipitation and shifting wind patterns will help suppress regional fire activity and disperse lingering particulate matter. Furthermore, total rainfall across most parts of the country is projected to slightly exceed the long-term average during the first half of November.

Favourable winds and wetter conditions are expected to help improve the haze situation in Singapore, the Meteorological Service Singapore said.

SINGAPORE: Haze conditions in Singapore are expected to improve as the inter-monsoon period sets in, the Meteorological Service Singapore said on Thursday (Oct 29).

Inter-monsoon conditions have been progressively setting in over Singapore and the surrounding region with the weakening of the southwest monsoon, the Met Service said.

The inter-monsoon period is characterised by light and variable winds, as well as increased showers and higher lightning activity.

“With the shift from persistent southeasterly or southwesterly winds to light and variable winds in the surrounding region, smoke haze is less likely to be transported from fires towards Singapore,” the Met Service said.

“Together with wetter conditions over Singapore and the nearby areas, the smoke haze situation for Singapore is expected to improve.”

Air quality was moderate across all regions in Singapore on Thursday.

Hourly PM2.5 readings were also in the normal range across the country, although levels briefly crossed into the elevated range in the west on Thursday morning.
