If you feel that the intense heat is wearing you down, get ready as the hot weather is likely to last for a few more days.
In the Philippine Atmospheric, Geophysical and Astronomical Services Administration’s (PAGASA) forecast heat index this week, Aparri, Cagayan’s maximum heat index could reach 42.2 degrees Celsius (°C) by Tuesday, June 1, and 41.6°C by Wednesday, June 2.
Dagupan City’s maximum heat index could reach 42.2°C by Tuesday and 41.3°C by Wednesday, while maximum heat index in Sangley Point, Cavite could reach 41.4°C by Monday, May 31 and 41.8°C by Tuesday.
PAGASA also said that maximum heat indices from May 31 to June 3, may reach 38.4℃-40.2℃ at the Ninoy Aquino International Airport, Pasay City and Port Area, Manila; and 38.6℃-40.5℃ at the Science Garden monitoring station in Quezon City
So far, the highest heat index in 2021 was registered in Dagupan City, Pangasinan at 53℃ on May 14.
What exactly does a heat index mean?
PAGASA defines “heat index” as a “human discomfort index” that gives the “apparent” temperature or what human perceive or feel as the temperature affects their body.
Simply put, the heat index is the measurement of how hot it feels when relative humidity is factored in with the actual air temperature.
The heat index is at least 3°C to 4°C higher than the actual air temperature.
But PAGASA said that full exposure to sunshine can increase the heat index by 8 degrees Celsius.
With heat indices between 32 to 41°C, PAGASA advised residents to observe “extreme caution” as “heat cramps and heat exhaustion are possible” and “continuing activity could result to heatstroke.”
Meanwhile, with heat indices between 41 and 54°C, PAGASA said there is impending “danger” as ” heat cramps and heat exhaustion are likely” and “heat stroke is probable with continued activity.”
If the heat index is over 54°C, PAGASA said there is “extreme danger” as “heatstroke is imminent.”
To prevent heatstroke, PAGASA has these tips.
1. Stay indoors as much as possible, if air conditioning is not available, stay on the lowest floor out of the sunshine.
2. Wear lightweight and light-colored clothing. Light colors will reflect the sun’s energy. Drink plenty of water regularly. The body needs water to keep cool.
3. Water is the safest liquid to drink during heat emergencies. Avoid drinking liquor because it dehydrates the body.
4. Eat small meals however eat more often. Avoid eating foods of high in protein which can increase metabolic heat.
