PAGASA Warns Some Areas Could Reach 52°C Heat Index
The worst is yet to come.
(SPOT.ph) Heat index forecasts are going from 40°C to 50°C real quick, in another warning from the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
High temperatures already surged beyond expectations in early April. Last week, Metro Manila hit a 40°C heat index, but this seems to have escalated as effects of El Niño continue to be felt. Now, PAGASA is warning that heat index could soar to 52°C in certain areas in the coming weeks.
“Based sa monitoring ng PAGASA sa matataas na discomfort index or heat index, may possibility na may areas po na makaranas nitong tinatawag na extreme danger, yung 52 pataas,” PAGASA Chief Ana Liza Solis said in an interview with PTV. “Historically kasi, ang mataas na temperatura na naitatala during the month of April as well as during the months of May.”
Solis did not specify the exact locations of these extreme danger zones, but mentioned that Cagayan Valley and Ilocos in Luzon are especially prone to higher temperatures. Coastal areas like Cavite and Batangas may also experience scorching heat.
But the worst is yet to come, with May anticipated to become even hotter than April due to the rise in relative humidity. This is why PAGASA Weather Specialist John Manalo told GMA Integrated News the same forecast of 52°C or higher next month.
“May possibility po, pero hindi po tayo 100% certain,” Manalo said. “During month of May, tumataas na rin po ang relative humidity. Dahil papunta na po tayo rainy season so 'yung moisture content ng hangin ay mas dumarami na rin as compared sa April and March.”

What is heat index?
Heat index is the "human discomfort index that gives the apparent temperature or what human perceive or feel as the temperature affecting their body,” according to PAGASA. High air temperature and high humidity result in a high heat index.
A heat index of 52°C and beyond falls within the “Extreme Danger” zone, where a heat stroke is imminent.
Anywhere between 32°C and 41°C can cause heat cramps and heat exhaustion especially if you're walking under the sun. Prolonged activity in this heat could also result in heat stroke.
In addition, those with pre-existing health conditions like heart disease, obesity, or diabetes may find that their symptoms worsen in high heat conditions because their bodies are under additional stress.
How to stay safe during extreme heat
It's important to take precautions in high heat environments, such as drinking plenty of water even if you’re not thirsty, taking breaks in the shade or air conditioning, and wearing light, loose-fitting clothing.
Avoid strenuous activities during the hottest part of the day, which is typically from 10 a.m. to 4 p.m. If you must be outside, apply a broad-spectrum sunscreen with an SPF of at least 30. Reapply every two hours.
There are also best practices to take note of inside the home. While electric fans can provide comfort, it will not prevent heat-related illness. Taking a cool shower or bath is a much better way to cool off according to the Center for Disease Control and Prevention.
