CHIANG RAI – The Governor of Chiang Rai, Chucheep Phongchai, has stepped up action on wildfire and toxic haze, with a strict no-burn order in place until May 10. Officials are also protecting Doi Pha Ngom, watching over high-risk groups, and keeping teams on alert around the clock.
The haze and PM2.5 crisis in Chiang Rai is no longer something people notice only from a gray sky or the smell of smoke. Official data now shows how serious the situation has become. According to Nakon Chiang Rai, the Office of Environment and Pollution Control 1, said the 24-hour average PM2.5 level across four upper northern provinces ranged from 40.3 to 198.3 micrograms per cubic meter.
Several areas in Chiang Rai reached levels that clearly affect health. The highest readings included 186.1 in Wiang Phang Kham, Mae Sai district, 152.2 in Wiang, Chiang Khong district, and 94.1 in Wiang, Mueang Chiang Rai district. For comparison, Thailand’s 24-hour standard is 37.5 micrograms per cubic meter.
Put simply, Mae Sai recorded nearly five times the national limit. Chiang Khong was more than four times over, while central Chiang Rai was about two and a half times above the standard. This is not a short-lived spike. It points to a wider crisis that now affects the environment, forests, and public health at the same time.
Wiang Pa Pao, Chiang Rai under the heaviest pressure.
On March 28, Governor Chucheep confirmed that wildfires had worsened between March 24 and 27, especially in the Wiang Pa Pao district. The Chiang Rai Office of Natural Resources and Environment recorded 65 hotspots across the province in the latest report. Wiang Pa Pao had the highest accumulated hotspot count, reaching 95 over the previous few days.
That number is more than a statistic. It shows how hard the area is being hit. When hotspots keep building up, the risk goes far beyond forest damage. Smoke can collect in mountain basins, fires can flare up again, and response teams must stay active with little time to rest.
One of the most closely watched locations is Doi Pha Ngom in Pa Ngio subdistrict, Wiang Pa Pao district. The area includes a sacred stupa and monks’ living quarters. Provincial officials said a forest fire spread heavily late at night on March 27. In response, the governor ordered the wildfire command center to send in joint teams from forest fire units, the Department of National Parks, district officials, local volunteers, and residents.
The operation was difficult from the start. The fire was burning in steep mountain terrain and deep forest, making access hard and increasing the danger of spread toward religious grounds. Teams had to hike in, build firebreaks, and use water to stop the flames from reaching the Tusita Pha Ngom monastic area.
By the morning of March 28, the Wiang Pa Pao district chief was on site directing the response. Officials also launched drones to inspect the area, look for flare-ups, and support 24-hour surveillance even after conditions began to improve.
Field information also showed that four separate wildfire points were found along the same zone. A combined team of 21 officers and volunteers worked from the afternoon of March 26 until the morning of March 27 before bringing the fires under control.
Early estimates put the damage to the dry evergreen forest at about 95 rai. That helps explain what each hotspot really means on the ground: it means real forest loss, real danger, and long hours of work for the people trying to stop it.
The burn ban now comes with strict enforcement.t
The latest order from the governor made the province’s position very clear. If conditions do not improve, the Royal Forest Department and the Department of National Parks may consider temporarily closing forest areas. At the same time, all agencies have been told to remind the public that all outdoor burning is strictly banned until May 10, 2026.
Anyone who breaks the order faces the highest legal penalties allowed. In addition, Chiang Rai plans to bring in military support from the Internal Security Operations Command to patrol high-risk areas, especially Wiang Pa Pao, starting March 30. The province also plans to request artificial rain operations as soon as humidity levels allow it.
This marks a shift from public requests for cooperation to firm control measures. With hotspots continuing to rise and PM2.5 levels far above the standard, Chiang Rai can no longer wait for the problem to ease on its own.
Air pollution is uneven across the province.ce
Official data also shows that the crisis does not hit every district the same way. Some areas face much worse PM2.5 levels than others. Mae Sai and Chiang Khong were both above 150 micrograms per cubic meter on the morning of March 28, while Mueang Chiang Rai measured 94.1. All of these readings fall into the range that already affects health.
At the same time, GISTDA reported that 33 provinces in the North and Northeast had high to very high pollution levels that same morning. Hotspot data from the previous day showed 2,302 hotspots across Thailand, most of them in conservation forests and national reserve forests. Neighboring Myanmar recorded 8,804 hotspots, while Laos had 4,189.
Those figures show that Chiang Rai’s haze crisis does not come only from fires inside the province. Regional pressure also plays a big role. Even if one fire is put out locally, smoke from outside the province and across the border can still keep air quality at dangerous levels.
While forest officers and local authorities fight fires on the ground, the health system is also working under pressure. On March 27, 2026, the Chiang Rai Provincial Public Health Office held its second emergency medical and public health operations meeting for haze and PM2.5 under the PHEOC system for the 2026 fiscal year.
Dr. Kongsak Chaichana, Deputy Provincial Public Health Doctor, chaired the meeting. He instructed health teams to take several urgent steps, including preparing enough clean rooms and face masks, visiting homebound and bedbound patients, and closely monitoring people with severe respiratory illnesses such as COPD and asthma. Every district was also told to open its own PHEOC for continued reporting and surveillance.
The key point is simple. Health agencies are not waiting for vulnerable patients to arrive at hospitals. They are trying to reach them first. That matters because long exposure to severe air pollution affects people differently. Some may only feel eye irritation or a sore throat. For older adults, children, and people with chronic illness, the risk can quickly turn into breathing trouble or an emergency visit.
Daily protection matters more than ever.
The Office of Environment and Pollution Control 1 advised people in areas with excessive PM2.5 to avoid outdoor activities. If they must go outside, they should wear proper PM2.5 masks and cut down time spent outdoors, especially during exercise. High-risk groups should stay in cleaner indoor spaces, keep medicine and necessary supplies ready, and contact a doctor quickly if symptoms get worse.
These recommendations match the broader advice to follow trusted air quality updates through tools such as Air4Thai from the Pollution Control Department and hotspot tracking systems from GISTDA. Other platforms, including Windy.com and weather apps, may help people plan travel or avoid risky areas. Still, when it comes to health alerts and official warnings, state sources remain the main reference.
If Wiang Pa Pao reflects the pressure from fires inside the province, Mae Fa Luang highlights the problem of cross-border wildfire. A provincial public relations report dated March 28 said tensions remained high in Mae Fa Luang district after officials found 16 hotspots in Ban Pa Kha Suk Jai. Crews managed to control those fires, but they still had to keep watch 24 hours a day.
Early on March 27, authorities also detected four new hotspots in Ban A Lae. By 8:00 a.m., reports said flames from the Myanmar side had spread toward Ban Mong Kao Lang in Thoet Thai subdistrict, an area that is steep and hard to access.
Mae Fa Luang district chief Pichet Srimarut then ordered security teams, volunteer defense units, disaster prevention officers, local administrative groups, village heads, and volunteer wildfire teams from every village to stay ready with water trucks and personnel at all times. The top concern was clear: stop the fire before it reaches homes.
This part of the crisis matters because it shows the limits of local control. When wildfire and smoke move across an international border, local teams can only focus on reducing damage and stopping flames from reaching communities and Thai natural resources.
Other districts are responding too.
Even though Wiang Pa Pao and Mae Fa Luang have received the most attention, other districts in Chiang Rai are also moving quickly. In Chiang Khong district, local leaders, village security teams, and volunteers in Khrueng and Huai So subdistricts have been patrolling and building firebreaks in community forest areas around Ban Si Lanna and Ban Kaen Nuea.
At Phu Chi Fa National Park, officials reported action on four hotspots in Ban Si Lanna. The response involved 22 personnel from the park, forest fire stations, local administration, and the Khrueng subdistrict municipality.
In Pa Daet district, teams from Mae Puem National Park, the Mae Puem forest fire station, and local volunteers joined forces after satellite data from Suomi NPP detected a hotspot near Ban Rong Chang Nuea. A total of 39 personnel responded, and early estimates put damage to the dry dipterocarp forest at around 72 rai.
Other areas, including Chiang Saen, Wiang Chai, and several community forests, also continued building firebreaks, patrolling, and clearing fuel sources throughout the same day.
All of these points point to one thing: no district can afford to relax. Even if some areas do not top the charts for smoke or hotspots, every district has to stay ahead of the risk. A small fire one day can become a province-wide burden very quickly.
Technology is becoming another layer of defense.
One clear pattern in this response is the growing role of technology. At Doi Pha Ngom, drones helped teams inspect damage from above and spot flare-ups that crews might miss from the ground. Satellite systems such as Suomi NPP and VIIRS are also helping officials track hotspots at the provincial, national, and regional levels through systems connected to GISTDA and local agencies.
For the public, technology has also become part of daily self-protection. Platforms like Air4Thai and GISTDA let people check air quality and hotspot trends before leaving home, going to school, heading to work, or traveling. In a period when pollution changes quickly, real-time information can be the first line of protection.
In comments shared by the provincial public relations office, the governor said the situation reflects the sacrifice of officers and volunteers in every village and community. Many have risked their safety day and night, without breaks, to protect the forest and preserve clean air for Chiang Rai residents.
That message goes beyond a simple thank you. It shows that the wildfire and haze crisis in 2026 is not only about saving forest land in the abstract. It is about protecting the air people breathe every day. The burn ban, patrols, clean rooms, drone use, volunteer mobilization, and plans for rainmaking all serve the same purpose: to reduce damage while conditions remain fragile.
Even so, this crisis also raises a bigger issue for Chiang Rai and the North as a whole. How can the province reduce its dependence on day-to-day emergency responses in the future? The current operations show commitment and sacrifice from many sides, but hotspot data at the national and regional levels suggest the pressure will not disappear soon. Border zones and mountainous terrain also make prevention far harder than in lowland areas.
So the main takeaway from March 28, 2026, is not only that the fire at Pha Ngom has started to ease, or that the province has issued a strict burn ban. The bigger point is that more people now see this for what it is, a shared crisis. It connects forest fires, dirty air, patients at home, warning systems, tracking technology, and public discipline across the whole province.
Putting out tonight’s fires still matters. But reducing next year’s fires and the number of people made sick by smoke may be the harder task. That work has to start now, before the next haze season arrives.
