PAGASA defines heat index as a human discomfort index that gives the “apparent” temperature or what a human perceives or feels as the temperature affects the body.
It is at least three to four degrees Celsius higher than the actual air temperature.
A heat index between 41℃ and 54℃ is under what the PAGASA considers as “danger” level due to the high likelihood of heat cramps and heat exhaustion.
