ILOILO City – The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) has advised residents of Iloilo to brace for the start of the dry season, which is expected to begin in the coming days or weeks.
PAGASA Iloilo received information from its central office on March 21, announcing the weakening of the northeast monsoon (Amihan), especially in Northern Luzon, and indicating its imminent termination.
“Once the northeast monsoon dissipates, we will officially enter the dry season,” said Charlie Depra, Weather Observer II of PAGASA Iloilo. “Right now, the northeast monsoon is already weak.”
Depra clarified that Ilonggos should not expect the same extreme heat experienced in 2024, as that period was marked by the El Niño phenomenon, which caused abnormally high temperatures and heat indices.
“Temperatures and heat index values will still rise during the dry season, but not as intensely as last year. We are not expecting extreme levels this time,” he added.
With the dry season approaching, Depra encouraged farmers to plan accordingly. He said rice planting is still possible but should be done in irrigated areas rather than rain-fed ones due to the reduced likelihood of significant rainfall.
“Those without access to irrigation can opt for root crops or other high-value crops that can survive with minimal rainfall,” Depra recommended.
He also reminded the public to stay hydrated, carry umbrellas, and watch out for heat-related illnesses such as heat stroke, heat cramps, and heat exhaustion.
PAGASA’s advisory outlined heat index categories and corresponding safety measures:
* Extreme Danger (≥52°C) – Cancel outdoor and physically strenuous activities such as field trips and sports events.
* Danger (42–51°C) – Limit activities for vulnerable groups such as the elderly and unacclimatized workers; schedule events during cooler hours.
* Extreme Caution (33–41°C) – Increase rest periods, hydration breaks, and substitute players more frequently in athletic activities.
* Caution (27–32°C) – Activities may proceed but participants should be monitored for signs of heat-related illnesses.
Technically, the Philippines experiences only two seasons: rainy (June to November) and dry (December to May). However, the term “summer” is colloquially used to describe the hot and dry months of March to May.
According to PAGASA, the transition to the dry season is marked by the retreat of the high-pressure area over Siberia, resulting in weaker northeasterly winds and a shift in wind patterns to easterlies.
“These signify the termination of the northeast monsoon and the start of the dry season and warmer conditions,” the agency said in a statement.
While a general increase in temperature is expected nationwide, PAGASA noted that rainfall may still occur due to easterlies, localized thunderstorms, and the ongoing La Niña phenomenon.
“The number of dry and warm days across the country will continue to increase, though isolated thunderstorms are also likely, especially in the afternoon or evening,” the agency added.
PAGASA urged the public and government agencies to implement measures to reduce heat stress, conserve water, and protect against health risks associated with the changing climate conditions./PN
