Hotter Days Ahead: Heatwave Warning in the Philippines

The state-run weather bureau has issued a warning for much hotter days ahead in the Philippines, with heat indexes reaching extremely dangerous levels. The forecast indicates that these scorching temperatures will persist until the second week of May. While the dry season typically brings warmer weather, the current soaring temperatures and heat indexes are being intensified by the El Niño phenomenon, although it has started to weaken, according to weather specialist John Manalo from the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA).

Impacts of the Heatwave

Manalo cited records showing that at least 36 key areas, including Metro Manila, have already been experiencing “dangerous” heat indexes ranging from 42 degrees Celsius to 51 degrees Celsius. As we progress towards the second week of May, it is expected that the number of affected areas across the country will increase further, with hotter weather and higher heat indexes becoming more evident.

The highest heat index recorded so far was 53 degrees Celsius in Iba, Zambales, on April 28, as reported by the PAGASA forecaster. Metro Manila also registered a record-breaking heat index on April 27. The heat index represents how the temperature feels to the human body when relative humidity is combined with the air temperature. Heat indexes ranging from 41 to 51 degrees Celsius are considered dangerous levels, where heat cramps and heat exhaustion are likely. Continued exposure to such extreme heat could also lead to heatstroke, according to PAGASA. Heat indexes above 52 degrees Celsius are classified as extremely dangerous.

Protective Measures and Precautions

In light of these hazardous conditions, Manalo emphasized the importance of taking necessary precautions. He advised the public to limit their time spent outdoors, especially between 10 a.m. and 4 p.m., when the heat is most intense. Staying hydrated by drinking plenty of water is crucial, while avoiding beverages such as coffee, tea, soda, and alcohol that can contribute to dehydration. Using umbrellas, wearing hats and sleeved clothing, and scheduling outdoor activities for the cooler parts of the day are additional measures that can help protect against the scorching heat.

Transition to Neutral Weather and La Niña

Looking ahead, Manalo mentioned that by June, there will be a transition to a neutral weather system and eventually to the onset of La Niña. During La Niña, sea surface temperatures in the western Pacific are warmer than normal, resulting in increased rainfall and the potential for severe floods. However, the state-run weather agency has predicted a possible delay in the start of the rainy season, which may occur in the second week of June.

At a briefing in the House of Representatives, Jorybell Masallo, Officer in Charge of the Farm Weather Services Section of PAGASA, highlighted that while El Niño will subside, its impact will continue to be felt until the second or third quarter of this year. Masallo further stated that advisories had been issued to agricultural areas, indicating a 60 percent chance of a La Niña phenomenon occurring in June, July, or August.


As the Philippines braces for hotter days ahead and the risk of dangerous heat indexes, it is crucial for individuals to stay informed and take appropriate measures to protect themselves from the scorching temperatures. By following the guidelines provided by PAGASA and remaining vigilant, the public can mitigate the risks associated with the ongoing heatwave. Additionally, the transition to a neutral weather system and the potential arrival of La Niña in the coming months bring the anticipation of relief in the form of increased rainfall. However, it is important to remain prepared for any delays in the onset of the rainy season.
