Who feels it first, and what to do
Heat does not reach everyone the same way. Outdoor workers, young children, older people and anyone with a heart or kidney condition carry the most risk once the index stays above 41°C for a few hours. Heat does not reach everyone the same way. Outdoor workers, young children, older people and anyone with a heart or kidney condition carry the most risk once the index stays above 41°C for hours.
Outdoor workers first.
Construction crews, farmers, riders and street vendors spend the hottest hours in direct sun. If the work cannot move, move the water: a glass every 20 minutes and a shaded break every hour.
Cool down early.
Get to shade or a fan, loosen clothing, wet your neck and wrists, and sip water. Stop if you feel dizzy, sick, or stop sweating. Those are warning signs, not tiredness.
Watch for 41°C.
PAGASA's scale calls 33 to 41°C extreme caution and 42 to 51°C danger. At 52°C and up, heat stroke is imminent. Confusion, a racing pulse or fainting needs a clinic at any level.
Questions
Heat, answered
Plain answers, with the band and the time it applies to.
What is heat index, exactly?
It is how hot it feels once humidity is counted. Your body cools by sweating, and damp air slows that down, so the air can be several degrees cooler than the index. PAGASA works it out from temperature and relative humidity. It is how hot it feels once humidity is counted.

Which heat index counts as dangerous?

Why give a band and not one number?
Heat index shifts through the day and between stations. Manila, Quezon City and Cebu can sit several degrees apart at the same hour, so the page shows the station reading and the band it falls in.

How often does this page change?
Twice a day during hot spells, in the morning and again after the 2 PM forecast. The index is recalculated whenever PAGASA issues a new bulletin for the station. Twice a day during hot spells, in the morning and again after the 2 PM forecast, whenever PAGASA issues a new bulletin.
