ILOILO City — Heat index levels across the Visayas have slightly decreased in some areas but remain elevated, with most locations still under conditions that pose health risks, according to the Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA).
According to the agency’s latest five-day monitoring and two-day forecast released at 5 p.m. on April 22, temperatures across Western, Central, and Eastern Visayas continue to fall within the “extreme caution” range of 33°C to 41°C, even as some stations reported modest declines compared to earlier peak readings this week.
In Western Visayas, Iloilo City, which previously reached 42°C, has slightly cooled but is still expected to register around 40°C to 41°C through April 23 and 24. Dumangas in Iloilo and Roxas City in Capiz likewise continue to record high heat indices, generally ranging from the upper 30s to about 40°C.
On Negros Island, La Carlota City in Negros Occidental posted earlier highs of up to 41°C but is now projected to hover between 38°C and 40°C. Dumaguete City in Negros Oriental remains comparatively lower, with readings between 36°C and 37°C.
Central Visayas is seeing more stable conditions, with Cebu and Bohol expected to experience heat indices between 36°C and 37°C, still within levels that can trigger heat-related stress with prolonged exposure.
In Eastern Visayas, readings remain uneven. Tacloban City is forecast to reach around 38°C, while Borongan and Guiuan in Eastern Samar continue to record higher values nearing 40°C. These areas had earlier recorded heat indices at or above the “danger” level and remain under close watch.
Compared with previous reports where some Visayas stations breached the 42°C threshold, the latest figures suggest a slight easing. However, Pagasa emphasized that conditions remain risky, as most areas are still within the extreme caution category where heat cramps and heat exhaustion are likely.
The weather bureau advised the public to avoid prolonged exposure to direct sunlight during peak hours, drink plenty of fluids, and wear light clothing.
Special attention is urged for vulnerable groups such as children, older persons, and individuals with underlying health conditions.
PAGASA attributed the continued high heat index to prevailing fair weather conditions, which allow heat to build up during the day despite isolated thunderstorms. Monitoring continues as elevated temperatures are expected to persist across the Visayas./PN
