MANILA, Philippines — Thirty areas across the country are expected to register “dangerous” peak indices above 42ºC (degrees Celsius) on Monday, said the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (Pagasa).
Based on Pagasa’s latest computed heat index forecast, Dagupan City in Pangasinan and Aparri in Cagayan are expected to reach the highest peak heat index at 47 °C (degrees Celsius).

Meanwhile, in Metro Manila, the heat index around Ninoy Aquino International Airport (Naia), Pasay City, is forecast to peak at 42ºC.
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.
