Malaysia and Thailand, Southeast Asia’s most visited countries, are urging tourists to take precautions amid extreme heat, including limiting strenuous outdoor activity and avoiding prolonged sun exposure.
Malaysia has recorded two deaths and 56 cases of heat-related ailments since the start of 2026, with 58% linked to physical activity in hot conditions, The Star newspaper reported.
Both fatalities were attributed to heat stroke.
One was that of a two-year-old child left inside a vehicle, while the other was a 42-year-old man who collapsed after participating in a marathon on Penang Island.
Malaysia is enduring a prolonged hot spell, with temperatures reaching 37 C in tourism hotspots such as Penang Island.
Authorities have issued nationwide heatwave alerts, urging both locals and tourists to stay hydrated, avoid the midday sun, and take precautions against heat-related illnesses.
In Thailand, the heat index in Bangkok surged past 52 C on May 4, reaching the “extreme danger” threshold and prompting authorities to urge tourists to avoid outdoor activity and remain alert for signs of heatstroke, Bangkok Post reported.
The Bangkok Metropolitan Administration issued a critical heat warning, with its environment department cautioning that the severe conditions significantly heighten the risk of heat-related illnesses.
The administration has set up “Heat escape rooms” at more than 300 spots across the city.
Malaysia received 10.6 million tourists in the first quarter of this year, up 5% year-on-year and making it the most visited country in Southeast Asia.
Thailand was second with 9.3 million arrivals, representing a slight year-on-year dip.
