Why Some Places in Thailand Are Cold

Thailand sits between 5 and 21 degrees north latitude and has a predominantly tropical climate. However, the northern and northeastern regions contain mountain ranges where elevation produces cold conditions that have no parallel elsewhere in the country. Doi Inthanon at 2,565 metres is the coldest place in Thailand and regularly records temperatures below freezing in winter. Cold air masses from China sweep south across Laos and directly hit the northeastern provinces like Sakon Nakhon, which holds Thailand’s official coldest temperature record of -1.4 degrees Celsius from 1974, despite sitting at a lower elevation than Doi Inthanon. The cool season runs from late October to February, with December and January the coldest months across all northern and northeastern destinations.

Doi Inthanon is the coldest place in Thailand and the highest peak in the country at 2,565 metres. Bangkok Post reported in January 2026 that this coldest place in Thailand recorded -5 degrees Celsius at grass level, with frost appearing on 29 occasions during that winter season and a record-breaking continuous frost spell of 12 days from December 22, 2024 to January 2, 2025. The summit ranger station typically records 2 degrees Celsius on the coldest mornings.
