The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) in Mactan warned Monday that the Cebu heat index may reach 42 degrees Celcius this April.

PAGASA-Mactan chief Engineer Al Quiblat said this level falls under the “danger” category, where heat cramps and heat exhaustion are likely, and heat stroke is possible with prolonged exposure.

He explained that the high heat index is due to the prevailing easterlies, which continue to affect most parts of the Philippines during the dry season.

The heat index measures the apparent temperature or what people perceive as the temperature felt by the human body, considering humidity and actual air temperature.

However, PAGASA-Mactan forecasted from 14 to 16 April for Cebu to expect partly cloudy skies and warm daytime temperatures.

The temperature will range from 27 to 33 degrees Celcius, while wind and coastal conditions are expected to remain generally stable throughout the period.

The public is advised to take precautionary measures during the hottest times of the day, particularly from late morning until mid-afternoon.

PAGASA recommends staying hydrated, limiting outdoor activities during peak heat hours, and monitoring updates for any further heat advisories.

Despite the generally dry and hot conditions, residents are also urged to remain alert on localized thunderstorms, which may still occur in the late afternoon or evening.
