Meanwhile, a heat index of 43 degrees Celsius is also expected in the northern portion of NCR, per Pagasa’s weather station in Quezon City.

Here are the forecast heat index of other areas under the “danger” category as reported by Pagasa’s weather stations:

• Iba, Zambales: 43 degrees Celsius
• Clark, Pampanga: 42 degrees Celsius
• Subic, Zambales: 43 degrees Celsius
• Sangley Point, Cavite: 44 degrees Celsius
• Tanauan, Batangas: 42 degrees Celsius

• Roxas City, Capiz: 45 degrees Celsius
• Mambusao, Capiz: 42 degrees Celsius
• Iloilo City, Iloilo: 44 degrees Celsius
• Dumangas, Iloilo: 43 degrees Celsius

Ranging from 42 degrees Celsius to 51 degrees Celsius, the heat index under the “danger” category could likely cause heat cramps and heat exhaustion, while heat stroke is probable with continued exposure to the sun.

The danger category is just before the “extreme danger” which is the highest category of heat index level, referring to temperatures of 52 degrees Celcius and beyond. Meanwhile, “extreme caution” ranges from 33-41 degrees Celsius and “caution” at 27-32 degrees Celsius.

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

On March 23, Pagasa also officially declared the start of the summer season, marking the end of the prevailing northeast monsoon or amihan which brought colder temperatures nationwide.

Also, Pagasa said El Niño still prevails nationwide, causing below-normal rainfall conditions that could bring “dry spells” or droughts in some parts of the country until the first quarter of 2024.
