PAGASA: 10 areas under 'danger' level heat index on June 4, 2026

Ten areas in the country are expected to experience “danger” level heat index on Friday, May 29, the state weather bureau PAGASA said.

Based on PAGASA’s five-day heat index forecast, the following areas may record heat index levels ranging from 42°C to 49°C:

49°C

• Infanta, Quezon

44°C

• Roxas City, Capiz

43°C

• Alabat, Quezon City
• Cuyo, Palawan
• BIA-Daraga, Albay
• Zamboanga City, Zamboanga del Sur

42°C

• Tuguegarao City, Cagayan
• Mambusao, Capiz

• Guiuan, Eastern Samar

Meanwhile, over 60 other areas are expected to experience “extreme caution” heat index levels ranging from 36°C to 41°C.

There are two areas also expected to experience “caution” heat index levels: Abucay, Bataan (30°C) and Tanay, Rizal (32°C).

The following areas are expected to record “not hazardous” heat index levels, or below 27°C:

• Baguio City, Benguet - 23°C
• BSU, La Trinidad, Benguet - 23°C
• Benguet Radar, Tuba, Benguet – 16°C

The heat index refers to the temperature felt by the human body when relative humidity is combined with actual air temperature. High humidity slows the evaporation of sweat, making it more difficult for the body to cool down.

PAGASA advised the public to limit their time outside and use umbrellas or caps when outdoors. The state weather bureau also recommended drinking lots of water and avoiding intake of tea, coffee, and sodas. —Vince Angelo Ferreras/LDF, GMA News
