The haze arose from Pelalawan where 102 hotspots were recorded in the morning, Nia Fadhila, analyst at the Pekanbaru meteorology, climatology and geophysics station, stated on Saturday.
Pelalawan is located in the south of Pekanbaru, with the wind blowing from southeast to southwest, she explained.
Executive General Manager of SSK II airport Yogi Prasetyo noted that in spite of the haze, operations at the Sultan Syarik Kasim II (SSK II) International Airport in Pekanbaru were normal.
The local residents of Pekanbaru wore face masks while venturing outdoors since the city’s air quality remained at an unhealthy level.
