TACLOBAN CITY — Extreme heat continues to grip Eastern Samar after Borongan City registered a heat index of 48 degrees Celsius on May 11, the highest recorded in the country so far this 2026 dry season, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa).
Pagasa classified the reading under the “danger” level, warning that prolonged exposure to such extreme heat conditions may lead to heat cramps, heat exhaustion, and even heat stroke.
Based on Pagasa’s monitoring, Borongan topped all other weather stations nationwide in terms of computed heat index, highlighting the intensity of the ongoing warm and dry season affecting Eastern Visayas.
The heat index reflects the temperature felt by the human body, combining actual air temperature and humidity levels. High humidity reduces the body’s ability to cool down through perspiration, making conditions feel significantly hotter than the actual air temperature.
With the continued threat of extreme heat, PAGASA advised the public to limit outdoor activities during peak hours from 10 a.m. to 4 p.m., stay hydrated, and wear light, breathable clothing to reduce the risk of heat-related illnesses.
Local authorities also urged residents—particularly senior citizens, children, outdoor workers, and individuals with existing health conditions—to take extra precautions as the region continues to experience intense heat conditions.
Despite occasional rain showers brought by the easterlies, PAGASA said hot and humid weather will likely persist in Eastern Visayas in the coming days.
