Infanta, a municipality in Quezon province, Philippines, is projected to experience a dangerous heat index of 45 degrees Celsius on June 5 and 6, 2026, despite the influence of Tropical Depression 'Ester' and the southwest monsoon. The Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) reported that the area has been facing persistently high heat index levels, including a peak of 49°C on June 3. Pagasa warns that heat index values between 42°C and 51°C can lead to heat cramps and exhaustion, prompting local officials to urge residents to remain cautious against heat-related illnesses. Residents are advised to hydrate adequately, wear light clothing, and limit sun exposure during peak hours. Meanwhile, Tropical Depression 'Ester' is moving northeast towards Taiwan and is expected to exit the Philippine Area of Responsibility by Saturday morning, while the southwest monsoon continues to bring rains to parts of western Luzon.
