CHIANG MAI, Thailand – Doi Inthanon National Park has recorded frost for the 25th consecutive time this winter as cold conditions continue across Thailand’s highest peak. Clear skies and strong visibility greeted visitors on January 2, creating favorable conditions for winter tourism and nature viewing.
Early morning measurements showed air temperatures of 3 degrees Celsius at the summit, with grass-surface temperatures dropping to 0.4 degrees. Kew Mae Pan recorded 4 degrees, while the park headquarters measured 9 degrees. Frost was observed around the summit area near Protection Unit No. 5.
The first frost of the season occurred on Nov. 24, 2025, with the lowest temperature recorded at 2 degrees on Nov. 27. The most extensive frost formed on Dec. 19 and 20, when ice covered much of the summit area, and grass-surface temperatures fell to minus 3.5 degrees.
Park officials advised visitors hoping to view frost to arrive early, between 6 a.m. and 8 a.m. Recommended locations include the summit parking area, the area in front of Protection Unit No. 5, the Kew Mae Pan viewpoint, and the Ang Ka nature trail.
Authorities urged visitors to drive cautiously, use low gear on steep roads, and wear adequate cold-weather clothing due to extremely low morning temperatures. Tourists were also reminded to follow park guidance to ensure safety and protect the natural environment. (NNT)
