Pagasa Issues Advisory on Persistent Warm Weather and High Heat Index Levels
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) announced on Saturday, April 11, 2026, that warm weather conditions will continue to prevail across the Philippines. In its early morning advisory, the agency detailed that the country can expect partly cloudy to cloudy skies with isolated rain showers or thunderstorms.
Weather Patterns and Wind Conditions
Moderate winds and seas are anticipated to affect the eastern section of Northern Luzon, while the rest of the nation will experience light to moderate winds accompanied by slight to moderate seas. This weather pattern underscores the ongoing atmospheric stability in the region.
Elevated Heat Index Forecasts
Pagasa highlighted significant heat index levels, with Dumangas in Iloilo potentially reaching up to 43°C. In Metro Manila, the heat index could soar between 39°C and 41°C. Other areas forecasted to experience high temperatures include:
- Sangley Point, Cavite: 41°C
- Ambulong, Batangas: 41°C
- San Jose, Occidental Mindoro: 41°C
- Zamboanga City: 41°C
Additionally, several locations may see heat indices of 40°C, such as Aparri and Tuguegarao City in Cagayan, Baler in Aurora, San Ildefonso in Bulacan, Tarlac City, Calapan in Oriental Mindoro, parts of Palawan, Legazpi City, Iloilo City, Catbalogan in Samar, Dipolog, Davao City, Cotabato City, and Butuan City.
Monitoring of Tropical Storm Sinlaku
Pagasa is closely monitoring severe tropical storm Sinlaku, which was last observed approximately 2,715 kilometers east of Northeastern Mindanao, outside the Philippine Area of Responsibility (PAR). The storm boasts maximum sustained winds of 110 kph and gusts reaching up to 135 kph. According to Pagasa Visayas, high temperatures are expected to persist while the storm remains under surveillance.
Expected Impact and Safety Recommendations
Weather specialist Ana Dumdum indicated that the heat index on Sunday, April 12, might reach 35°C to 36°C, falling under the extreme caution level. She advised the public to limit sun exposure, stay hydrated, and wear light clothing to mitigate heat-related risks.
Furthermore, a tropical depression being monitored remains distant from the country and outside PAR. It may enter PAR and be named Caloy, but is projected to curve near the boundary. Pagasa assured that no direct effects are anticipated at this time, although isolated rains could occur in the third week of April due to localized thunderstorms.
