The highest heat index is expected in Dagupan City, Pangasinan, with temperatures potentially soaring to 48°C.

The heat index, also known as the apparent temperature, factors in both humidity and air temperature to show how hot it actually feels.

Temperatures from 42°C to 51°C, considered "dangerous," raise the chances of heat-related issues like cramps or exhaustion. 

Too much sun exposure can also lead to heat stroke.

PAGASA advised to reduce outdoor activities, stay hydrated, and avoid specific beverages to prevent heat-related illnesses.

Using umbrellas, hats of wearing long sleeves when outdoors is also recommended.

The state weather bureau also suggested scheduling intense activities for cooler parts of the day.
