The government warns of a rise in PM 2.5 dust levels from 14-16 Jan 2026, emphasizing strict control of pollution sources and a ban on burning. It is also considering extending Work From Home measures to reduce traffic volume and pollution in urban areas.
On 15 January 2026, Ms. Lalida Perdvivatana, Deputy Spokesperson of the Prime Minister's Office, stated that the Air Pollution Communication Center (APCC) of the Pollution Control Department issued a warning about increasing PM2.5 dust levels from 14–16 January 2026. Areas requiring special attention include Bangkok and its vicinity, as well as the upper central and northeastern regions. This is due to closed atmospheric conditions near the surface combined with low air ventilation rates, causing dust to accumulate and not disperse effectively. The situation is expected to ease after 16 January.
Ms. Lalida said the government has instructed the Pollution Control Department to work closely with provincial natural resources and environment offices to communicate and coordinate with local agencies to strengthen pollution source control, especially banning burning during closed air conditions. Coordination with Bangkok authorities is underway to consider tightening Low Emission Zone measures and extending Work From Home durations to reduce traffic and urban pollution. Additionally, the Royal Rainmaking and Agricultural Aviation Department is conducting weather modification to break the temperature inversion layer to alleviate dust levels. The government has also sent a letter to the ASEAN Secretary-General requesting cooperation from neighboring countries regarding transboundary pollution.
Ms. Lalida added that air quality reports on 14 January 2026 at 12:00 indicated rising PM2.5 levels nationwide, particularly in Bangkok and its vicinity, the central region, and the northeast. Some Bangkok districts, including Bang Rak, Pathum Wan, and Sathorn, recorded PM levels exceeding the red standard, while other areas were at the orange level, beginning to impact public health.
The APCC urges the public to monitor air quality before leaving home, avoid outdoor activities during high dust periods, use public transport to reduce traffic, and wear protective masks or dust filters if going outside. People should strictly follow Ministry of Public Health guidelines and can track air quality updates via the Air4Thai website or Air4Thai mobile app.
