As for Metro Manila, Pasay City is expected to have a heat index of 41°C, while Quezon City is expected to have a temperature of 40°C in the “extreme caution” category.

These situations can cause heat cramps and heat exhaustion.

The heat index measures the level of discomfort an average person experiences due to the combined effects of temperature and humidity.

Pagasa declared the start of the summer season in March, as the country is suffering from the effects of El Niño, or the weather phenomenon that increases the chance of below-normal rainfall.

Nevertheless, Pagasa expects one to two tropical cyclones to occur this month.
