On April 7, 2026, PAGASA forecasts that San Jose in Occidental Mindoro and Dumangas in Iloilo will experience a “danger level” heat index of 42°C, posing risks of heat cramps, exhaustion, and even heat stroke. Residents in these areas are advised to take precautions against extreme heat.

The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) defines the heat index as the measure of how hot it feels when relative humidity is factored in with actual air temperature. A heat index between 42°C and 51°C falls under the “danger” category, which can cause serious health issues if people are exposed for prolonged periods.

According to PAGASA’s latest bulletin,San Jose, Occidental Mindoro and Dumangas, Iloilo are expected to reach this threshold on Tuesday, April 7. The forecast was released at 5 p.m. on April 6, highlighting the need for residents to prepare for potentially hazardous conditions.

The warning comes shortly after PAGASA declared the end of the northeast monsoon (Amihan) season on March 23, officially marking the start of the dry season. With hotter days ahead, the risk of heat-related illnesses is expected to rise across the country.

Health experts emphasize that during danger-level heat indices, people should stay hydrated, avoid outdoor activities during peak hours (10 a.m. to 4 p.m.), wear light clothing, and seek shade or air-conditioned spaces whenever possible. Vulnerable groups such as children, the elderly, and those with pre-existing health conditions are at higher risk of heat stroke.

Local governments in Occidental Mindoro and Iloilo are expected to issue advisories reminding residents to take precautions. Schools and workplaces may also adjust schedules to minimize exposure to extreme heat.

The situation underscores the growing impact of climate change on weather patterns in the Philippines, where rising temperatures and humidity levels are making summers increasingly dangerous. PAGASA continues to monitor conditions nationwide and will issue further warnings if more areas reach danger-level heat indices.

For residents in San Jose and Dumangas, April 7 will be a critical day to prioritize safety and health. With the heat index forecast at dangerous levels, vigilance and preventive measures are essential to avoid heat-related emergencies.
