45ºC heat index logged in Dagupan City; ‘dangerous’ level in 4 other areas
MANILA, Philippines — A “dangerous” peak heat index of 45ºC (degrees Celsius) was recorded in Dagupan City, Pangasinan on Thursday, said the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (Pagasa).
Apart from Dagupan City, Pagasa said it has also recorded a 43ºC heat index in Catarman, Northern Samar, and a 42ºC heat index in Laoag City, Ilocos Norte; Puerto Princesa City, Palawan; and Roxas City, Capiz.
Pagasa defines heat index as “a measure of the contribution that high humidity makes with abnormally high temperatures in reducing the body’s ability to cool itself.”
Once it reaches 42ºC to 51ºC, Pagasa considers it part of the “danger category” as it may cause heat cramps, heat exhaustion, and even heat stroke during continued exposure.

Pagasa continues to advise the public to prevent the effects of high heat by limiting the time spent outdoors; drinking plenty of water; avoiding tea, coffee, soda, and liquor; using umbrellas and hats and wearing sleeved clothing outdoors; and scheduling heavy-duty activities on the cooler periods of the day.
Symptoms of heat-related illnesses include: heavy sweating, exhaustion or fatigue, dizziness or lightheadedness, blacking out or feeling dizzy when standing, weak but fast pulse, nausea, and vomiting.
In cases of emergency, Pagasa reminded the public to do the following:
- Move the person to a shady spot and lie him/her down with legs elevated
- If conscious, have them sip cool water
- Remove clothing, apply cool water to the skin, and provide ventilation
- Apply ice packs to the armpits, wrists, ankles, and groin
- Bring to a hospital immediately
