For several days, heavy smog and PM2.5 pollution have plagued Thailand. A red alert was issued in all districts on the morning of 2 December. According to the GISTDA, the entire city was covered in smog at around 6 am, and visibility was reduced.
There is also a health risk to citizens. If the situation worsens, it is recommended to strengthen the action.
Pollution situation in the capital
Nong Khaem district recorded a local 102.5 µg/m³. There are Bang Bon and Bang Khae, where it is more than 101. Around 5 am, the smog began to accumulate rapidly and increased the risk of respiratory problems.
At the same time, Thawi Watthana and Bang Khun Thian reached 100. Therefore, the alternatives are advised to stay.
National weather situation
The country’s best Samut Saen is identified as the most polluted province. Natthaburi, Nakhon Pathom and Bangkok also went to the dangerous limit. A total of 15 provinces entered the red alert campaign. The situation in 25 more provinces has moved to the ‘orange zone’. As a result, residents of the country are advised to take precautions.
New health guidelines
On 4 December, 25 PM 2.5 municipalities averaged 43.7 µg/m³. Bang Rak, Sathon, Bang Kholay and Pathum Wan were the danger areas. Therefore, it is recommended to use PM 2.5 protective masks if someone goes outdoors.
It is recommended to complete high-quality work. It is also recommended to seek medical attention quickly.
Social Media Reactions
With the increase in pollution, online public opinion is becoming more difficult. Some say that there were no health problems, but it was difficult to go out. They also said that many sensors are counting fog as pollution, so you have to check it on the political app.
Someone else commented that this pollution will reduce people’s life expectancy, but the number of cars is expected to be right. The welcome and the public’s concern and anger are expressed.
WFH urgent advice
However, the situation is getting worse. BMA institutions can respond if they have to work. It is expected that there will be less air pollution, and pollution will also decrease. That is why, public and private organizations are encouraged to connect to the WFH network. Updates are being made on Facebook pages. Citizens are also advised to get information from the helpline.

@thethaigerofficial PM2.5 Pollution Surges Across Thailand’s Provinces Thailand is grappling with dangerously high levels of PM2.5 air pollution, with 37 provinces exceeding safe thresholds this week. The northern and northeastern regions are the worst affected, including Chiang Mai, Mae Hong Son, and Loei, where levels have spiked beyond international safety standards. Bangkok has also recorded elevated levels in five districts, prompting urgent health warnings. Authorities forecast worsening conditions between 21–27 March, especially in urban centres and the east. The south remains relatively unaffected, maintaining low pollution levels for now. Health officials are urging the public to limit outdoor activities, wear protective masks, and monitor symptoms, particularly among vulnerable groups. The situation reflects a seasonal pattern that has become all too familiar, sparking renewed calls for long-term environmental reform. With respiratory risks increasing, the issue is once again placing air quality at the centre of public concern. Authorities and citizens alike must work together to prioritise sustainable solutions and improve monitoring systems. Stay alert and take precautions as conditions worsen. #ThailandAirPollution #PM25Crisis #ChiangMaiSmog #BangkokAirQuality #EnvironmentalHealth #PollutionAlert #ThailandNews #PublicHealthWarning #CleanAirThailand #SustainableSolutions
