Thailand's Winter Season Start Delayed for 2026
The Thai Meteorological Department reports that the onset of winter is delayed this year, with rain still persisting across the country.
According to a report by Khaosod Online, the Thai Meteorological Department (TMD) has clarified that Thailand has not yet officially entered the winter season as of October 22, 2026. While the country typically transitions into cooler weather during late October or early November, current conditions remain characterized by scattered rainfall and temperatures that have not yet reached the threshold for the winter season.
The TMD provided historical data for the past four years, noting that the start of winter varied significantly: October 23 in 2025, November 3 in 2024, November 14 in 2023, and October 29 in 2022. For 2026, officials expect the season to begin later than the historical average and conclude around mid-February 2027. The projected average minimum temperature for upper Thailand is expected to be between 22.0 and 23.0 degrees Celsius.
For residents and travelers, this means that the expected drop in temperatures and the arrival of drier, cooler air will be delayed. Those planning trips to northern regions or mountainous areas should monitor official TMD updates, as the transition to winter conditions remains subject to atmospheric changes. The exact date for the official start of the 2026 winter season has yet to be confirmed by the department.
