Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA) weather specialist Obet Badrina issued a warning of intensified heat index levels across the country this April. Here are some details according to the report of The Philippine Star.

Heat Index Forecast

According to PAGASA’s heat index forecast, temperatures in two areas of the country could reach up to 43°C this Monday. These areas include Aparri in Cagayan and Catarman in Northern Samar. Additionally, two other locations may experience heat indexes of up to 42°C, including Pili in Camarines Sur and Zamboanga City.

When the heat index reaches the ‘danger level,’ prolonged exposure to the sun can lead to heat cramps and heat exhaustion for individuals.

Metro Manila Alert

In Metro Manila, temperatures may soar to as high as 40°C, prompting extreme caution among residents.

PAGASA also warned of exhaustion or excessive fatigue, profuse sweating, dizziness, weakness with a rapid pulse, dizziness, and vomiting.

2. Hydrate, Hydrate, Hydrate!
  • Drink plenty of water throughout the day to stay hydrated, especially when temperatures soar.
  • Check on friends, neighbors, and family members who may be at higher risk and encourage them to stay hydrated.
3. Seek Cool Environments
  • Find air-conditioned spaces like shopping malls or libraries to cool off when needed.
  • Never leave children or pets unattended in parked vehicles, even for a short time.
4. Dress for the Heat
  • Wear lightweight, light-colored, loose-fitting clothing to help your body stay cool.
  • Don a hat and apply sunscreen with SPF 15 or higher to protect your skin from the sun’s harmful rays.

Visayas Records High Heat Index

Meanwhile, in the Visayas region, PAGASA recorded a heat index of 37 degrees Celsius in Cebu. This reading falls under the ‘extreme caution’ category, indicating the potential for heat cramps, exhaustion, and even heat stroke with prolonged exposure to the sun.

Forecasts for May

Heat Index

Looking ahead, PAGASA anticipates that May, traditionally the hottest month of the year, will bring even higher heat index levels, possibly reaching up to 47 degrees Celsius, categorized as ‘dangerous.’

The combination of the El Niño phenomenon and the onset of the hot dry season contributes to the elevated heat index levels.

Classification of Heat Index

  • 27 to 32 degrees Celsius: Caution (fatigue possible with prolonged sun exposure)
  • 33 to 41 degrees Celsius: Extreme caution (heat cramps and exhaustion likely)
  • 42 to 51 degrees Celsius: Danger (heat stroke probable with continued exposure)
  • 52 degrees Celsius and beyond: Extreme danger (imminent heat stroke)

PAGASA emphasizes the importance of staying informed and taking necessary precautions to mitigate the risks associated with extreme heat.
