Thai Meteorological Department Predicts Extreme Heat Above Forty-Two Degrees Celsius in 2026 Summer
Officials forecast a later, intense summer season with temperatures exceeding forty-two degrees Celsius across parts of Thailand
The Thai Meteorological Department has issued a forecast indicating that Thailand’s summer of 2026 will bring prolonged periods of extreme heat, with maximum temperatures expected to exceed forty-two degrees Celsius in some regions.
The official outlook anticipates that the summer season will begin later than usual, around the end of February, and extend through mid-May, marked by alternating episodes of scorching heat and convective thunderstorms.
Temperatures are expected to climb particularly during April and May, with many inland and northern provinces facing days of severe heat that could surpass forty-two degrees.
Meteorological officials emphasized that heat intensity is in line with established criteria for “very hot” conditions, defined as daily maximum temperatures of forty degrees Celsius or more.
The forecast underscores the need for heightened public awareness and preparedness measures across affected provinces, with authorities advising residents to take precautions against heat-related health risks and to stay informed on evolving weather updates.
This projection comes amid wider concerns about climate variability and rising heat extremes in Southeast Asia, as official data shows that Thailand has experienced significant hot spells in recent years.
The department’s seasonal forecast reflects both long-range weather patterns and short-term variability, highlighting the potential for intense heat waves to impact daily life, agriculture and energy demand across the country.
