Brunei, an independent sultanate that is surrounded by East Malaysia's Sarawak state on Borneo, had been affected by the haze from Kalimantan. Rains brought some relief, and on 8 October, the Pollutant Standards Index had dropped to 46, which is within the "good" range.[6] There was a brief spell of clear skies during the first week of Hari Raya, following a spell of rainy weather. But the haze returned on 31 October,[7] with the Department of Environment, Parks and Recreation recording a PSI of 49.[8][9]
