Luzon heat index could hit 45°C

If you’re in Luzon this weekend, brace yourself — it’s going to be hot.

The latest report from PAGASA (Philippine Atmospheric, Geophysical and Astronomical Services Administration) warns that the heat index in several areas could reach a scorching 45°C.

On Saturday, 19 locations — including Pasay City and Quezon City — were already placed under “Dangerous” heat index levels, ranging from 42°C to 51.

Some of the hottest areas include Laoag in Ilocos Norte, Dagupan City in Pangasinan, Bacnotan in La Union, Tuguegarao City in Cagayan, ISU Echague in Isabela, Baler in Aurora and Iba in Zambales.

Central Luzon also recorded high levels, with CLSU Munoz in Nueva Ecija, Cubi Point Subic Bay in Olongapo City, TAU Camiling and Hacienda Luisita in Tarlac all affected.

Tayabas City in Quezon, Sangley Point in Cavite, Infanta and Alabat in Quezon, San Jose in Occidental Mindoro and Aborlan in Palawan were also included in the warning.

Looking ahead to Sunday, Sangley Point in Cavite City is expected to experience the highest heat index at 45°C. Other areas across Luzon are projected to see heat indices ranging between 36°C and 44°C.

To put that into perspective, a heat index of 36°C to 41°C falls under the category of “Extreme Caution,” while anything between 42°C to 51°C is considered “Danger.”

In these conditions, there’s a higher risk of heat cramps, heat exhaustion and potentially even heat stroke.

PAGASA is urging the public to take necessary precautions: limit outdoor activities, wear light and breathable clothing and stay hydrated — especially between 10 a.m. and 4 p.m. when the heat tends to peak.
