Toxic Smog Chokes Chiang Mai as Tourists Avoid Songkran Travel

CHIANG MAI, April 3, 2026 — Thick toxic smog has engulfed northern Thailand ahead of the Songkran holiday, driving tourists away from Chiang Mai and raising fresh concerns over the country’s environmental and tourism outlook.

Chiang Mai was ranked the world’s most polluted city this week, as worsening wildfires and agricultural burning pushed air quality to hazardous levels, according to data from air monitoring firm IQAir.

Hotel occupancy in the northern tourist hub has dropped sharply to around 30–40% ahead of the peak holiday period, local tourism officials said.

“Concerns about smog and rising oil prices are influencing tourists’ decisions,” tourism operator Punlop Saejew told local media.

Tourism operators are urging authorities to take swift action to control fires and restore confidence in the region, warning that prolonged pollution could further damage the local economy.

The smog has been fueled by a surge in wildfires and seasonal agricultural burning, including cross-border haze affecting multiple northern provinces.

Thailand faces recurring air pollution crises during the dry season, but the current conditions come at a critical time as the country prepares for Songkran, one of its busiest tourism periods.
