As temperatures soar during April and May, the hottest months in the Philippines, PAGASA forecasts Dagupan City, Pangasinan, will hit the ‘danger’ heat index of 42ºC today. This level poses significant risks such as heat cramps and exhaustion, with symptoms ranging from fatigue to vomiting, warns the Department of Health.
Heat indexes between 42ºC and 51ºC are considered particularly hazardous, increasing the risk of severe health issues like heat stroke, which can lead to unconsciousness or seizures without proper medical intervention.
Other regions facing high but not ‘danger’ level heat indexes include Iba, Zambales at 41ºC, and 39ºC in locations such as NAIA, Pasay City, and Laoag City, Ilocos Norte, among others. The heat index, a reflection of apparent temperature influenced by humidity, suggests hotter conditions than actual air temperatures alone.
PAGASA advises the public to stay hydrated, minimize outdoor activities, and avoid drinking caffeinated or alcoholic beverages. Wearing protective clothing and scheduling strenuous tasks for cooler times of the day are also recommended.
Ana Liza Solis, the chief of PAGASA’s Climate Monitoring and Prediction Section, noted that although 2024 was the warmest year due to an intense El Niño, 2023 may not reach those extremes. However, with the current northeast monsoon and potential rain from convective activities, the overall climate remains warm and dry.
Solis highlighted that the hottest temperatures might reach up to 39ºC in Northern Luzon, while Metro Manila could see highs of 37ºC during these scorching months.
Last year marked significant temperature records across areas like Clark, Pampanga at 39.1°C, with various locations setting new historical highs. Despite these records, the La Niña alert suggests the possibility of light rain remains this year.
