Sweltering heat continues to grip the country, and according to state weather agency PAGASA, it’s far from over. The Philippine Atmospheric, Geophysical and Astronomical Services Administration on Monday warned that the heat index—already at dangerous levels—may peak by May.
Over the weekend, San Ildefonso in Bulacan recorded a blistering 47 degrees Celsius heat index, the highest so far this year. But PAGASA cautioned that even hotter days could be ahead.
Veronica Torres, a weather specialist at PAGASA, explained that both actual temperature and humidity are likely to climb in the coming weeks. She said the heat index typically peaks around the first week of May, although extreme temperatures have also been recorded as early as April.
Danger-level heat felt across the country
San Ildefonso wasn’t the only place enduring dangerously high temperatures. PAGASA noted at least 15 other locations reached “danger-level” heat indices, ranging from 42 to 45 degrees Celsius.
Aparri in Cagayan logged the second-highest heat index at 45°C. Other hotspots included Sangley Point in Cavite City, Puerto Princesa in Palawan, and Daet in Camarines Norte—all at 44°C. Meanwhile, 43°C was recorded in Dagupan City, Tuguegarao City, Ambulong in Batangas, Dumangas in Iloilo, and Zamboanga City.
The heat index, which combines air temperature and humidity, indicates how hot it actually feels. PAGASA warns that indices above 42°C are considered hazardous. At this level, people face increased risks of heat cramps, heat exhaustion, and even heat stroke with prolonged exposure.
Casiguran in Aurora, Subic Bay in Olongapo City, Masbate City, La Carlota in Negros Occidental, and Metro Manila also hit 42°C—posing serious health concerns for millions.
Heat relief unlikely as hot winds dominate Luzon, Visayas
Despite the scorching conditions, cooler weather isn’t coming anytime soon—especially for Luzon and Visayas. According to Rhea Torres of PAGASA, the hot and humid weather is being caused by the easterlies, or warm winds blowing in from the Pacific Ocean.
However, some parts of Mindanao may get a brief reprieve from the extreme heat. Rain showers are likely due to the presence of the intertropical convergence zone, a weather system known for bringing thunderstorms.
Still, the public across the country is urged to stay alert. Authorities recommend limiting outdoor activities during peak hours, staying hydrated, and monitoring daily advisories.
PAGASA reiterated that staying updated is key to avoiding heat-related illnesses. Extreme weather like this is no longer unusual and may persist longer due to climate patterns influenced by El Niño.
