The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) registered the 39.0 degrees Celsius heat index around 1:50 p.m. at its Science Garden monitoring station in Quezon City.

The actual temperature was recorded at 35.0 degrees Celsius.

People perceived or felt warmer than the air temperature reading due to high temperature and humidity in the atmosphere.

Heat index, which combines air temperature and relative humidity, is higher by at least 2 to 3 degrees Celsius from the actual air temperature.

PAGASA has warned the public of the various effects of the forecast heat factor to a person’s body.

Take a “caution” if the forecast heat index is between 27 and 32 degrees Celsius (80-90 degrees Fahrenheit) because fatigue is possible with prolonged exposure and activity, while continuing activity could result in heat cramps, PAGASA said.

Consider “extreme caution” if the forecast heat factor is between 32 and 41 degrees Celsius (90-105 degrees Fahrenheit) because heat cramps and heat exhaustion are possible, while continuing activity could result in heat stroke.

Expect “danger” if the forecast heat factor is between 41 and 54 degrees Celsius (105-130 degrees Fahrenheit) as heat cramps and heat exhaustion are likely, while heat stroke is probable with continued activity.

There is “extreme danger” if the forecast heat index is over 54 degrees Celsius (over 130 degrees Fahrenheit) because heat stroke is imminent.
