Bangkok: A warning has been issued regarding a potential surge in PM2.5 levels between January 14-16, 2026, with recommendations for strict control over pollution sources and the extension of work-from-home arrangements. Deputy Spokesperson Ms. Lalida Periswiwatana of the Prime Minister's Office has highlighted the concerns raised by the Air Pollution Control Communication Center (APCC) of the Pollution Control Department about the increasing levels of PM2.5 particulate matter during this period. Special attention is required in Bangkok and its surrounding provinces, as well as the upper central and northeastern regions of Thailand, due to stagnant air conditions and low ventilation rates, leading to the accumulation of particulate matter. An improvement in the situation is expected after January 16.
According to Thai News Agency, the government has instructed the Pollution Control Department, in collaboration with provincial offices of natural resources and environment, to work closely with local agencies to enhance pollution control measures. This includes a ban on burning during stagnant air periods. The government is also coordinating with the Bangkok Metropolitan Administration to consider upgrading measures for low-emission zones and extending work-from-home periods to reduce urban pollution and traffic. Additionally, the Department of Royal Rainmaking and Agricultural Aviation is set to implement weather modification measures to alleviate the particulate matter situation. Cooperation has also been sought from neighboring countries through communication with the ASEAN Secretary-General regarding transboundary pollution.
Ms. Lalida reported that as of January 14, 2026, at 12:00 PM, PM2.5 levels had risen in many areas, notably in Bangkok and its surrounding provinces, the Central region, and the Northeast. Specific areas in Bangkok, such as Bang Rak, Pathum Wan, and Sathorn, registered PM2.5 levels exceeding the standard, classified as red level, while other areas were at the orange level, starting to impact public health.
The National Energy Policy Office (NEPO) has urged the public to monitor air quality before leaving home, avoid outdoor activities during high particulate matter periods, and use public transportation to minimize traffic. If outdoor activities are necessary, wearing a face mask or other dust protection equipment is recommended, along with following the Ministry of Public Health's guidelines.
