Filipinos are urged to take precautions against extreme heat as the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) forecasts dangerously high temperatures in several parts of the country on Tuesday, April 15, 2025.
According to PAGASA’s 5 p.m. bulletin on Monday, 14 areas are expected to experience “danger level” heat index values, which could lead to serious health risks if proper precautions aren’t taken.
A heat index — also known as the “apparent temperature” — represents how hot it feels when humidity is factored in with the actual air temperature. PAGASA considers a heat index of 42°C to 51°C to be under the danger category, where heat-related illnesses such as cramps, exhaustion, and even heat stroke are more likely with prolonged exposure or physical activity.
Areas Forecasted to Reach Danger Levels
The following areas may hit 43°C in heat index:
- Sangley Point, Cavite City
- Puerto Princesa City, Palawan
- Virac (Synop), Catanduanes
- Dumangas, Iloilo
- La Granja, La Carlota, Negros Occidental
Meanwhile, a 42°C heat index is forecasted in:
- Cubi Point, Subic Bay, Olongapo City
- San Ildefonso, Bulacan
- TAU Camiling, Tarlac
- Ambulong, Tanauan, Batangas
- NAS-UPLB, Los Baños, Laguna
- San Jose, Occidental Mindoro
- Cuyo, Palawan
- CMU Agromet, Musuan, Bukidnon
- Davao City
In Metro Manila, residents can expect heat indices of 40°C in both NAIA, Pasay City and Science Garden, Quezon City — still classified under the extreme caution category.
Staying Safe During Extreme Heat
With large parts of the country facing unusually high heat, experts advise the public to take the following precautions:
- Hydrate frequently. Drink water even before you feel thirsty. Avoid alcohol, caffeine, and sugary drinks, which can lead to dehydration.
- Limit outdoor activities, especially between 10 a.m. and 4 p.m., when the sun is at its strongest.
- Wear lightweight, loose, and light-colored clothing to help your body stay cool.
- Use umbrellas, hats, or sunblock when going outside, and stay in shaded or air-conditioned areas as much as possible.
- Take cool showers or baths to help lower your body temperature.
- Check on vulnerable individuals such as the elderly, children, and people with preexisting conditions, who are more prone to heat-related illnesses.
- Never leave children or pets inside parked vehicles. Even with the windows slightly open, temperatures can rise to deadly levels within minutes.
- Eat light meals and avoid hot or heavy foods that can raise body heat.
Looking Ahead
As El Niño continues to influence the region, the Philippines is expected to endure more days of extreme heat in the coming weeks. PAGASA encourages the public to remain vigilant, monitor local weather updates, and take preventive measures seriously.
