Despite widespread rains across many regions, 36 areas in the Philippines are forecasted to experience extreme heat today, with heat indices ranging from 42 to 46 degrees Celsius. The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) has issued a warning for these areas based on a two-day forecast.
Critical Areas and Expected Temperatures
Dagupan City in Pangasinan is expected to face the highest heat index, potentially reaching a scorching 46 degrees Celsius. Similarly, Bacnotan in La Union and Iloilo City are predicted to endure a heat index of 45 degrees Celsius.
PAGASA also highlighted that the Ninoy Aquino International Airport in Pasay City might see temperatures peaking at 44 degrees Celsius, with the Science Garden in Quezon City reaching up to 42 degrees Celsius.
Other areas experiencing severe heat include:
- Dumangas, Iloilo and Zamboanga City: 44 degrees Celsius
- Laoag City, Ilocos Norte; Tuguegarao City, Cagayan; Echague, Isabela; Iba, Zambales; Casiguran, Aurora; Subic Bay, Olongapo City; Sangley Point, Cavite; Ambulong, Tanauan, Batangas; Puerto Princesa City, Palawan; Catbalogan, Samar; and Dipolog, Zamboanga del Norte: 43 degrees Celsius

Understanding the Heat Index
The heat index measures how hot it feels when relative humidity is factored in with the actual air temperature. A heat index between 42 and 46 degrees Celsius is categorized as “dangerous,” posing significant health risks such as heat cramps, heat exhaustion, and heat stroke. PAGASA advises residents in these areas to stay hydrated, avoid strenuous outdoor activities, and seek cooler environments whenever possible.
Mitigation and Safety Measures
Given the severe heat conditions, PAGASA urges the public to take necessary precautions. Employers should ensure that workers have access to cool, shaded, or air-conditioned areas and provide adequate breaks to prevent heat-related illnesses. Schools and outdoor event organizers are advised to adjust schedules to avoid peak heat periods.
Local government units and health agencies are also on high alert to respond to potential heat-related emergencies. Public health campaigns are being intensified to educate communities about the dangers of extreme heat and the importance of preventive measures.
The extreme heat in these 36 areas poses a significant risk to health and safety. Vigilance and proactive measures are essential to mitigate the adverse effects of this severe weather phenomenon.
