Heat index in 7 areas may reach ‘danger level’ on March 28, 2025 — PAGASA

A “danger level” heat index is expected in 7 areas in the country on Friday, PAGASA said in its latest advisory.

A heat index between 42 to 51 °C falls under the "danger" classification, posing health risks such as heat cramps, heat exhaustion, and heat stroke with continuing activity.

Based on its 5 p.m. March 26 bulletin, the state weather bureau said Dagupan City, Pangasinan is expected to experience a 46 °C heat index while General Santos City, South Cotabato could reach up to 43 °C.

Meanwhile, the following areas could reach up to 42°C heat:

• Aparri, Cagayan
• Tuguegarao City, Cagayan
• Cubi Point, Subic Bay, Olongapo City
• Sangley Point, Cavite City
• Cuyo, Palawan

The heat index measures how hot it feels to the human body, factoring in humidity along with the actual air temperature.

In Metro Manila, NAIA Pasay City will have a heat index of 40°C, while Science Garden in Quezon City will be facing a heat index of 39°C.

A heat index from 33°C to 41°C is under the “extreme caution” category, where heat cramps and heat exhaustion are possible, and continuing activity could lead to heat stroke.
