Kuala Lumpur is expected to experience clearer weather till Saturday due a momentary change in wind pattern, said the Malaysian Meteorological Department.
The haze situation, however, is expected to continue until the end of the south-west monsoon season.
"We are now at the last stage of the south-west monsoon season whereby the wind is flowing from Sumatra to the peninsula. Expect it to last for another two to three weeks," Meteorological Department's National Weather Centre senior meteorologist Dr Hisham Mohd Anip told The Straits Times.
Mr Hisham added the haze situation in Malaysia is very dependant on the open burning in Indonesia.
According to the Department of Environment website, the air pollutant index (API) at the Batu Muda station in Kuala Lumpur is 97 at 4pm compared to 100 and 102 at 3pm and 2pm respectively.
API in the 0 to 50 range is good, 51 to 100 is moderate, 100 to 200 is unhealthy; 200 to 300, very unhealthy; and above 300, hazardous.
