Pagasa defines heat index as “a measure of the contribution that high humidity makes to abnormally high temperatures in reducing the body’s ability to cool itself.”

Currently, Pagasa’s heat index classification system consists of four categories:

  • Extreme Caution: 33 to 41 degrees Celsius
  • Danger: 42 to 51 degrees Celsius
  • Extreme Danger: 52 degrees Celsius and beyond

Pagasa advised 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.
