Meanwhile, the heat index in Metro Manila is expected to peak at the Ninoy Aquino International Airport (Naia), Pasay City, at 43ºC.
According to Pagasa, the heat index is “a measure of the contribution that high humidity makes [to] abnormally high temperatures in reducing the body’s ability to cool itself.”
When it ranges from 42ºC to 51ºC, Pagasa 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.
Regarding the lowest heat indexes, Baguio City and La Trinidad in Benguet are expected to peak at only 29ºC and 28ºC, respectively.
