State weather bureau PAGASA announced Tuesday that it will temporarily suspend the issuance of heat index declarations with the start of the rainy season.

In a social media post, the agency said the move aims to provide “accurate and timely information” on hazards associated with the rainy season.

The public is advised to access heat index data through PAGASA’s automatic weather stations and iHeatMap, available under the weather tab on the PAGASA website.

Additionally, PAGASA encourages the public to seek official announcements from local authorities for guidance on heat-related precautions.

Issuance of heat index reports will resume on 1 March 2026, coinciding with the start of the warm season in the Philippines.

Despite the onset of the rainy season, PAGASA warned of possible monsoon breaks — or periods with little to no rainfall.

According to the latest weather forecast, the southwest monsoon is currently affecting most of Luzon, while the intertropical convergence zone (ITCZ) is influencing weather conditions in Southern Mindanao, including the Davao Region, Bangsamoro Autonomous Region, and Zamboanga Peninsula.

“Cloud cover is expected to thin over the western section of Luzon, but its effects may still be felt, particularly in the Ilocos Region as well as in Zambales and Bataan where rains are still likely,” said PAGASA Weather Specialist Rhea Torres.

Torres added that most parts of Luzon are expected to see gradual weather improvement starting Wednesday.

No gale warning has been issued, but moderate sea conditions are expected along the seaboards of Western Luzon and Northern Luzon.
