CHIANG RAI – Northern Thailand’s ongoing struggle with seasonal wildfires and the resulting “death smog” has reached a critical turning point this year. According to the latest figures from the Forward Operating Center for Wildfire, Haze, and Dust Pollution Control, there is a glimmer of hope: the total number of hotspots across the northern region has dropped by more than 3% compared to 2025.
However, a closer look at the data reveals a “tale of two Norths.” While some areas are seeing clearer skies, seven key provinces are currently losing the battle against the flames. Chiang Rai and Chiang Mai, in particular, are facing a dramatic surge in fire activity, prompting officials to mobilize every available resource to prevent a public health disaster.
By the Numbers: A Regional Overview
From January 1st to April 5th, 2026, satellite monitoring and ground assessments tracked the wildfire situation across 17 northern provinces. The data provides a comprehensive look at where the fires are burning and how this season compares to previous years.
The Good News
- Total Hotspots: 48,529 points detected nationwide.
- Net Decrease: This represents a drop of 1,737 hotspots (3.46%) compared to the same period last year.
- Reduced Burn Area: Between January and February, the total burned area covered 2,279,049 rai. This is a significant 32.21% decrease (over 1 million rai) from 2025.
The Areas of Concern in Northern Thailand
Despite the overall decline, the raw numbers in specific provinces remain dangerously high. The “Leaderboard of Fire” for 2026 currently stands as follows:
- Mae Hong Son: 6,977 hotspots
- Chiang Mai: 6,840 hotspots
- Lampang: 6,690 hotspots
The Surge: Why Some Provinces Are Burning Brighter
While the regional average is down, seven provinces have seen a worrying spike in activity. The most alarming increases are happening in the upper North, where rugged terrain makes firefighting extremely difficult.
Provinces with Increasing Hotspots
- Chiang Rai: Saw a massive jump of 1,106 points, a 62.10% increase over last year.
- Chiang Mai: Increased by 2,809 points, rising by 41.07%.
- Phrae: Up by 286 points (8.76%).
- Phayao: Up by 210 points (7.77%).
- Mae Hong Son: Up by 222 points (3.17%).
- Lamphun: Up by 41 points (1.90%).
The sharp rise in Chiang Rai and Chiang Mai is particularly concerning for tourism and local health, as these areas often trap smoke due to their bowl-like geography.
To fight a fire, you have to know what is fueling it. The Forward Operating Center categorized the hotspots by land type to help authorities understand the source of the smoke.
Breakdown by Land Type
- National Forest Reserves: 23,605 hotspots (The largest category).
- Protected Forest Areas: 19,458 hotspots.
- Land Reform Areas: 2,227 hotspots.
Breakdown by Land Activity
The vast majority of the burning is happening in deep forest areas rather than open farmland.
- Forest Areas: 40,989 points.
- Corn & Shifting Cultivation: 2,951 points.
- General Agricultural Areas: 2,109 points.
This data suggests that while “slash and burn” agriculture remains a factor, the bulk of the current crisis is fueled by forest fires—often started by foraging or accidental spread—in hard-to-reach mountainous zones.

Burned Area Analysis: The Impact on the Ground
The “burned area” metric is just as important as the number of “hotspots,” as it measures the total footprint of the damage. Interestingly, the provinces with the most fire points aren’t always the ones with the most charred land.
From January to February 2026, the provinces with the highest total burned acreage were:
- Phetchabun: 535,596 rai
- Nakhon Sawan: 524,498 rai
- Phichit: 216,593 rai
The fact that the total burned area has decreased by over 32% suggests that firefighting teams are getting faster at containing blazes before they spread across thousands of acres, even if the number of individual ignitions remains high in some spots.
The Forward Operating Center has emphasized that the battle is far from over. With the dry season still in full swing, the report calls for a “total mobilization” of forces.
The Strategy for April 2026
- Continuous Patrolling: Ground teams are increasing their presence in National Forest Reserves to catch “fire-starters” and extinguish small blazes before they grow.
- Air Support: Helicopters are being used for water drops in the steep mountains of Chiang Mai and Chiang Rai, where ground crews cannot safely go.
- Inter-Agency Cooperation: The Center is coordinating between the military, local volunteer firefighters, and forestry officials to ensure resources are moved to “hot zones” as they appear.
The Path Forward: What This Means for Residents
For the people of Northern Thailand, these statistics aren’t just numbers—they represent the air they breathe. The decrease in total burned area is a major win for the environment, but the 62% surge in Chiang Rai shows that the threat is moving, not disappearing.
Health officials continue to advise residents in high-hotspot provinces to wear N95 masks and avoid outdoor activities during the early morning hours when PM2.5 levels are typically at their peak.
As we move deeper into April, all eyes remain on the skies. The success of the 2026 season will depend on whether the mobilized land and air forces can turn the tide in the seven provinces currently seeing an upward trend. For now, the message from the Center is clear: we cannot afford to be complacent.
