Cavite is expected to experience extreme heat on Monday, April 20, as the heat index in several areas continues to climb to dangerous levels, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
Based on the weather bureau’s two-day heat index forecast, the temperature in Sangley Point, Cavite City may reach a “danger level” heat index of 42°C.
Monday marks the second consecutive day that Cavite has experienced dangerous heat index levels, following earlier peaks that reached up to 44°C.
According to weather specialist Charmagne Varilla, speaking on DZRH’s Operation Tulong, the continued presence of a ridge of a high-pressure area over extreme northern Luzon is limiting cloud formation and rainfall, contributing to the ongoing rise in temperatures.
Aside from Cavite, several areas are also expected to experience extreme caution-level heat. San Ildefonso, Bulacan is forecast to record a heat index of 41°C, while multiple locations are expected to reach 40°C, including Tuguegarao City in Cagayan, Coron and Cuyo in Palawan, Davao City, Zamboanga City, and Cotabato City.
In Metro Manila, the heat index may rise to around 39°C, particularly in Pasay City, bringing continued uncomfortable and humid conditions for residents.
Despite the intense heat, localized thunderstorms remain possible in Metro Manila and other parts of the country, which may bring brief relief but also sudden weather changes.
PAGASA classifies heat index values between 42°C and 51°C as “danger,” where heat cramps and heat exhaustion are likely, and heat stroke becomes probable with prolonged exposure.
Meanwhile, heat index levels ranging from 33°C to 41°C fall under the “extreme caution” category. Under these conditions, heat cramps and heat exhaustion may occur, and continued physical activity in the heat could lead to heat stroke.
PAGASA continues to remind the public to take necessary precautions against extreme heat, including limiting outdoor activities, staying hydrated, wearing light clothing, and seeking shade or cooler environments whenever possible to avoid heat-related illnesses.
