DEKAD NO. 13 1- 10 MAY 2026

Philippine Agri-Weather Forecast

During the forecast period, the country will be influenced by the easterlies, ridge of the High-Pressure Area (HPA), Low Pressure Areas (LPAs), and localized thunderstorms.

In the first half of the dekad, Visayas and Mindanao will experience cloudy skies with scattered rainshowers and thunderstorms due to the easterlies. Meanwhile, the rest of the country will have partly cloudy to cloudy skies with isolated rainshowers and thunderstorms.

As the period progresses, cloudiness with scattered rainshowers and thunderstorms will continue over Visayas and Mindanao due to the presence of an LPA. Another LPA may develop into a tropical cyclone; however, it is unlikely to directly affect the country. The rest of the country will continue to experience partly cloudy to cloudy skies with isolated rainshowers and thunderstorms.

Winds will generally come from the east to southeast over Northern Luzon, while the rest of the country will experience winds from the east to northeast. These wind conditions are expected to persist throughout the forecast period.

Sea conditions will be slight to moderate over most seaboards of the country. However, moderate to rough seas are expected over Extreme Northern Luzon. Similar sea condition may also occur along the eastern seaboards of Visayas and Mindanao due to the LPA.

ENSO ALERT SYSTEM STATUS: EL NIÑO ALERT (Updated: 22 April 2026)
ENSO-neutral conditions prevail over the Tropical Pacific. Most climate models suggest that El Niño is likely to emerge in the June-July-August season with 79% chance and is likely to persist until early 2027.

El Niño increases the likelihood of below-normal rainfall conditions, which could bring negative impacts (such as dry spells and droughts) in some areas of the country. However, above-normal rainfall conditions during the Southwest Monsoon Season (Habagat) may also be experienced over the western part of the country.

PAGASA will continue to closely monitor the development of this ENSO phenomenon. All concerned government agencies and the general public are encouraged to keep on monitoring and take precautionary measures against the impending impacts of El Niño.

Farm Advisories

Farmers are advised to maximize field operations such as planting, fertilization, and harvesting during the early part of the day when conditions are still favorable. Ensure adequate soil moisture for newly planted rice and corn, while avoiding water stress in vegetables through timely irrigation. At the same time, prepare drainage systems and maintain dikes to prevent waterlogging during sudden afternoon downpours. Crops should be closely monitored for pest and disease outbreaks, which may increase under alternating dry and wet conditions. Proper field management and flexible scheduling of farm activities are recommended to reduce risks and sustain crop productivity under this variable weather condition. Farmers are advised to continuously monitor DOST-PAGASA updates regarding Low Pressure Areas (LPA) and the possible development of tropical cyclone. Sudden weather changes may occur, which can bring heavy rainfall, strong winds, and localized flooding, potentially affecting rice, corn, and vegetable production activities. It is recommended to adjust farm operations based on official forecasts, secure field drainage systems, and ensure readiness for possible adverse weather conditions to minimize crop losses.
