Monthly Philippine Agro-climatic Review and Outlook

December 2025

Simplified Version Monthly Agroclimatic Review and Outlook
 


For the month of December, the country was affected by several weather systems, including the northeast monsoon, low pressure areas (LPAs), Intertropical Convergence Zone (ITCZ), easterlies, shear line, three tropical cyclone, and localized thunderstorms.

As shown in Figure 1, most parts of the country experienced below to near normal rainfall conditions with patches of above normal conditions over Ilocos Sur and Negros Island Region.

Tropical Depression Wilma, which affected the country from December 4 to 7, 2025, interacted with the Northeast Monsoon (Amihan) and the prevailing shear line, significantly enhancing adverse weather conditions across several regions. This combination of weather systems generated strong to occasionally gusty winds and widespread heavy rainfall over large portions of the country. As a result, multiple weather-related hazards were recorded, including flooding in low-lying and coastal areas and landslides in mountainous and upland communities. According to the National Disaster Risk Reduction and Management Council (NDRRMC) Situational Report dated 09 December 2025, the most affected areas included most parts of MIMAROPA, Regions V (Bicol), VII (Central Visayas), and VIII (Eastern Visayas), the Caraga Region, and the Negros Island Region (NIR).

The highest recorded rainfall for the month was at Borongan Synop Station (816.7 mm), followed by Infanta, Quezon Synop Station (753.4 mm), and Legaspi City, Albay Synop Station (715.3 mm).

Agroclimatic Outlook for January 2026
  • The weather systems that will affect the country in January are the Northeast (NE) monsoon, the ridge of high-pressure areas (HPAs), shear line, easterlies, low-pressure areas (LPAs), Intertropical Convergence Zone (ITCZ), tropical cyclones, and localized thunderstorms.
  • Zero or one (0 to 1) tropical cyclones (TC) may enter or develop within the Philippine Area of Responsibility (PAR) during the month.
  • As illustrated in Figure 2, near- to above-normal rainfall conditions are expected across most areas of the archipelago, except in the Zamboanga Peninsula, where way above-normal rainfall is forecast.

FARM ADVISORY

Before sunrise, lightly sprinkle or spray water on frost-affected crops to melt the frost and gradually transfer heat to the plants, reducing the risk of sun-burning on frozen leaf surfaces. Where possible, cover vulnerable beds with cloths or other protective materials at night to trap warmth. Keep essential tools such as hoses, sprayers, and water buckets ready for quick response if frost forms. During periods of heavy rain, use waterproof covers or tarpaulins to protect harvested produce, drying grains, and farm equipment, and reinforce farm structures such as greenhouses, sheds, and trellises to withstand strong winds and rainfall. Clear drainage ditches and canals regularly to allow excess water to flow away from fields and prevent waterlogging. Store seeds, feeds, fertilizers, and other farm inputs on raised pallets or in covered areas to avoid spoilage. In areas frequently affected by heavy rains or flooding, consider planting flood-tolerant crop varieties or crops with shorter growing cycles, and plan planting and harvesting schedules based on weather forecasts to avoid peak rainy periods. Since prolonged humidity and wet conditions favor pests and fungal diseases, practice integrated pest management (IPM) and conduct regular field inspections.
