Independent cities

Olongapo City is politically independent from Zambales but is included here for regional coverage. It uses a representative point because the source boundary file does not include its geometry.

Data limits

Weather and heat index are model estimates for one coordinate. The province boundary is administrative geography, not a heat measurement. Cooling-place records start as unverified public facilities unless a reviewer has checked public access and cooling suitability.

What the category means

Below 27 °C heat index

The estimated heat index is below the lowest PAGASA hazard band. Heat can still affect sensitive people, especially during direct sun or strenuous activity.

  • Drink water regularly and take breaks in the shade.
  • Check on older adults, young children, and anyone with chronic illness.
  • Watch for changes in official weather advisories.

Sa madaling salita: Hindi pa nasa hazard band ng PAGASA, pero uminom pa rin ng tubig at magpahinga sa lilim.
