All schools in Selangor, Kuala Lumpur, Putrajaya, Negri Sembilan and several parts of Sarawak will be closed on Monday due to the worsening haze.
The schools closed in Sarawak are those located in Kuching, Sri Aman and Kota Semarahan.
On Sunday, the Education Ministry said in a statement that the closure was because the Air Pollutant Index (API) readings in these areas reached unhealthy and very unhealthy levels.
As of 11am Sunday, the API readings for Port Klang was 252, Shah Alam (281), Petaling Jaya (232), Putrajaya (206) and Batu Muda (256).
In Sarawak Sri Aman recorded an API reading of 188, Kuching (139) and Samarahan (145).
On Sept 15, schools in Putrajaya, Kuala Lumpur, Selangor, Negri Sembilan and Malacca were closed after API readings in some of the areas rose to nearly 200.
An API reading of between 0 and 50 is considered good, 51 to 100 (moderate), 101 to 200 (unhealthy), 201 to 300 (very unhealthy), and 301 and above (hazardous).
The haze in Malaysia is caused by open burning and forest fires in Indonesia.
