Olongapo City residents faced severe heat conditions Wednesday as the heat index climbed to 43 degrees Celsius, according to readings from the Barretto automatic weather station at 10:15 a.m. The extreme temperatures raised concerns about the risk of heat-related illnesses among the population, particularly for vulnerable groups spending extended periods outdoors.

The City Disaster Risk Reduction Management Office issued warnings as thermometer readings approached dangerous levels. Such elevated heat indices can lead to heat exhaustion and heat stroke, conditions that require immediate medical attention if symptoms such as dizziness, weakness, or excessive fatigue develop.

The sustained high temperatures underscore the challenges facing residents during the hot season. Authorities advised the public to limit outdoor activities during peak heat hours, increase fluid intake, and seek shade whenever possible to mitigate health risks associated with prolonged heat exposure.
