A heatwave has intensified across Southeast Asia today, April 7, 2026, as a massive “thermal dome” pushes temperatures to record-breaking levels.
According to the latest satellite mapping, air temperatures in major hubs like Bangkok, Hanoi, and Phnom Penh have hit a scorching 38°C, while cities in the Philippines such as Tuguegarao are seeing highs of 35°C.
However, the real danger lies in the soaring Heat Index, which combines high humidity with these extreme temperatures. Forecasters warn that the “feels-like” temperature in parts of Thailand and the Philippines is surging past 45°C, reaching “Extreme Danger” levels that can cause rapid heatstroke.
With authorities in Malaysia and Thailand already initiating cloud seeding and public health red alerts, residents are urged to remain indoors during peak hours as this historic April surge continues to bake the region.
