On June 7, 2023, Atimonan, a municipality in Quezon, Philippines, recorded a concerning heat index of 44°C despite the rainy season. The reading was taken at 2:12 p.m. by the town's Automated Weather Station. In response, the Atimonan Disaster Risk Reduction and Management Office issued a public advisory urging residents to limit sun exposure, particularly between 10 a.m. and 4 p.m., to mitigate risks of heat cramps, exhaustion, and potential heat stroke. Earlier that same day, the heat index had already reached 42°C at noon. The heat index, which combines air temperature and humidity to reflect how hot it feels, is critical for assessing heat-related health risks. The Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) classifies heat index values in the range of 42°C to 51°C as dangerous. Although Pagasa has stopped regular heat index forecasts since June 5 to focus on weather updates for the rainy season, it continues to advise monitoring for high temperatures and adhering to health precautions against heat-related illnesses.
