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


The US National Weather Service describes heat index as “the apparent temperature, what the temperature feels like to the human body when relative humidity is combined with the air temperature.”

Heat indices ranging from 42 °C to 51 °C fall under the “danger” category, and people exposed to these heat indices are prone to heat cramps, exhaustion, and even heat stroke.

To prevent the effects of the intense heat, weather, Pagasa advised the public to limit time spent outdoors, ensure adequate hydration, avoid tea, coffee, soda and liquor, use umbrellas, hats and sleeved clothing outdoors and schedule strenuous activities on the cooler periods of the day.
