In Imus City, Cavite, local authorities also reminded residents to observe safety measures after the heat index reached 42.2°C as of 1:05 p.m.

According to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa), the heat index measures the level of discomfort people experience due to the combined effects of air temperature and humidity.

The weather bureau classifies heat index levels into four categories: “caution” (27°C to 32°C), “extreme caution” (33°C to 41°C), “danger” (42°C to 51°C), and “extreme danger” (52°C and above).

Peak heat conditions are usually experienced from midday until late afternoon.

Authorities advised the public to limit outdoor activities during peak hours, drink plenty of water to stay hydrated, wear light-colored, loose-fitting clothing, avoid leaving children or pets inside parked vehicles, and regularly check on vulnerable individuals, including children, senior citizens, and those with existing medical conditions.

Pagasa suspended the issuance of heat index forecasts beginning June 5 to prioritize accurate and timely weather advisories during the rainy season.
