PAGASA Officially Declares Start of Summer Dry Season in the Philippines
The Philippine Atmospheric, Geophysical and Astronomical Services Administration, the country's official weather bureau, has formally declared the beginning of the summer dry season, effective today, March 23, 2026. This announcement comes as the agency officially confirms the termination of the northeast monsoon, known locally as "amihan," which had previously brought a series of rainfall events and cooler temperatures to various regions across the nation.
Weather Patterns and Public Advisories
With the shift in seasonal patterns, PAGASA has issued a warning that the entire country should prepare for significantly hotter temperatures in the coming weeks and months. However, the weather bureau noted that brief or intermittent showers and occasional cool spells may still occur due to the influence of prevailing easterlies. Additionally, thunderstorms are possible, particularly during the afternoon hours, as atmospheric conditions become more conducive to convective activity.
The Department of Science and Technology agency strongly advises the public to take proactive measures to avoid heat-related health issues. Recommended precautions include:
- Staying hydrated by drinking plenty of water throughout the day
- Avoiding prolonged exposure to direct sunlight, especially during peak heat hours
- Wearing lightweight, light-colored clothing to help regulate body temperature
- Being aware of the symptoms of heat stress and seeking medical attention if necessary
Historical Context and Seasonal Transition
This year's declaration follows a similar pattern from the previous year, when PAGASA announced the start of the summer season on March 26, 2025. The annual transition from the cooler, wetter northeast monsoon to the hotter, drier summer period represents a significant meteorological shift that affects agriculture, water resources, energy consumption, and daily life across the Philippine archipelago.
The formal declaration serves as an important benchmark for various sectors, including agriculture, tourism, and public health, allowing them to adjust their planning and operations accordingly. As the dry season progresses, monitoring of temperature extremes, rainfall patterns, and potential drought conditions will remain a priority for the weather agency and related government departments.
