Meanwhile, in Metro Manila at the Ninoy Aquino International Airport (Naia) in Pasay City, it is forecast to hit a peak of 43ºC.
The lowest expected heat indices remain at Baguio City, Benguet and La Trinidad, Benguet at 27ºC and 28ºC, respectively.
The heat index is the “measure of the contribution that high humidity makes with abnormally high temperatures in reducing the body’s ability to cool itself.”
Once it ranges from 42ºC to 51ºC, the state weather bureau automatically tags it as part of the “danger category,” as it increases the risk for heat-related illnesses such as heat cramps, heat exhaustion, and even heat stroke.
