Sangley Point reports day’s highest heat index at 50°C

A heat index of 50°C, the day's highest, was recorded at PAGASA's synoptic station in Sangley Point, Cavite City, the state weather bureau said Wednesday.

This high point is followed by Ambong, Tanauan City with 49°C, Dagupan City with 48°C, the Science City of Munoz with 46°C and Calapan City, Roxas City, and San Jose, Occidental Mindoro with 45°C.

The heat index is the measure of the temperature that a person feels in contrast to the actual air temperature.

Essentially, it measures "human discomfort" and is computed by factoring in the humidity as well as the air temperature.

PAGASA again warned of dangers associated with a heat index between 41 to 54°C such as heat cramps and heat exhaustion which may lead to heat stroke amid continued physical activity.
