Review of Land Fires and Smoke Haze Situation for Second Fortnight of July 2018

1.1 In the northern ASEAN region, no significant hotspot activities were observed.

1.2 In mid-July, drier weather in the southern ASEAN region contributed to an increase in hotspot activities, particularly in northern Riau and West Kalimantan. Smoke haze from hotspots in northern Riau was observed to spread northward across the Strait of Malacca towards Peninsular Malaysia. Several clusters of hotspots with smoke plumes were also observed in West Kalimantan and western Sarawak. These hotspots were short-lived and shower activities toward the end of July 2018 helped to subdue the hotspot activities there.

1.3 Figures below show satellite images over the ASEAN region in the second fortnight of July 2018.

Review of Land Fires and Smoke Haze Situation for First Fortnight of July 2018

1.1 During the review period, hotspot activities in the northern ASEAN region remained subdued due to the prevailing wet weather conditions.

1.2 In the southern ASEAN region, there were increased hotspot activities observed in Sarawak and West Kalimantan in the latter half of the fortnight, as dry weather conditions set in over the region. Smoke plumes were observed emanating from some of the hotspots.

Review of Land Fires and Smoke Haze Situation for Second Fortnight of June 2018

1.1 During the review period, there were isolated hotspots detected in the ASEAN region, but the overall hotspot activities were generally subdued due to the wet weather.

1.2 During the brief periods of drier weather, there were a few hotspots with thin smoke plumes observed on one or two days in central Sumatra. However, the smoke plumes were localised and short-lived.
