The Northeast Monsoon, locally known as "Amihan," continues its pervasive influence across vast swathes of the Philippines, bringing characteristic cool temperatures, cloudy skies, and scattered light rains over Luzon and Visayas. Even as the nation anticipates the gradual transition to its warm and dry season later this month, the lingering cold has driven temperatures to seasonal lows in upland areas, with Baguio City registering 9.0 degrees Celsius and La Trinidad, Benguet, plummeting to 7.5 degrees Celsius on Friday morning, marking the chilliest readings of the Amihan season.
This extended grip of the monsoon impacts daily life, agricultural considerations, and maritime activities for millions across the archipelago. Fisherfolk face hazardous sea conditions, farmers adjust planting schedules, and urban dwellers contend with a prolonged period of brisk weather, underscoring the dynamic and sometimes unpredictable nature of the nation's climate even as it approaches its traditional "tag-init" or summer season. The sustained cool air masses and accompanying rainfall highlight the need for continued vigilance and adaptation across diverse communities.
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) reported that the Amihan remains the dominant weather system, particularly affecting the northern and central regions of the country. According to PAGASA's daily weather forecast issued on Friday, March 14, regions such as Bicol, Eastern Visayas, Caraga, Aurora, Quezon, Oriental Mindoro, and Marinduque are experiencing cloudy skies accompanied by light rains. Further north, areas including Batanes, Cagayan, Isabela, Nueva Vizcaya, Apayao, Kalinga, Mountain Province, Ifugao, Northern Samar, and Eastern Samar are also under similarly cloudy conditions with light precipitation.
The capital, Metro Manila, along with the rest of Luzon and Visayas, the Zamboanga Peninsula, and Northern Mindanao, are also under the monsoon's sway, observing partly cloudy to cloudy skies with isolated light rains. While these conditions generally pose no significant direct impact in most areas, they contribute to the overall cooler atmospheric envelope blanketing the islands.
The prevailing cold air mass has led to notably cooler temperatures beyond the northern highlands. Manila's Science Garden in Quezon City recorded 19.7 degrees Celsius, dipping below 20 degrees for the fourth time this Amihan season. These figures underscore the persistent strength of the cold winds, offering a prolonged respite from the heat typically associated with late March in the tropics.
Beyond the immediate comfort or chill, the Amihan’s influence extends profoundly to maritime conditions. Strong to gale-force winds are currently sweeping over Northern Luzon and the eastern sections of Central Luzon, Southern Luzon, and Visayas, resulting in rough to very rough sea conditions. PAGASA has issued explicit gale warnings, advising small sea vessels, including motor bancas, against venturing out, and urging larger vessels to exercise extreme caution in these treacherous waters. Wave heights in these areas could reach up to 4.5 meters, posing considerable risks to sea travel and coastal communities.
In contrast, the eastern section of Mindanao and the remaining parts of Luzon and Visayas are experiencing moderate to strong winds with moderate to rough seas, necessitating careful navigation. The rest of Mindanao observes lighter winds and calmer coastal waters, offering a temporary reprieve from the more turbulent conditions prevalent further north.
Weather specialist Loriedin De La Cruz-Galicia of PAGASA noted that the northeast monsoon will continue to affect the entire country, bringing low temperatures and dry air, especially in parts of Luzon and mountainous areas. She further explained that while some areas are experiencing more consistent light rains, the general outlook for Metro Manila and the rest of the country remains partly cloudy to cloudy with isolated light rains.
Despite the generally light nature of the monsoon rains, localized thunderstorms can occur, particularly over Mindanao, potentially leading to flash floods or landslides during severe downpours. Residents in these susceptible regions are consistently advised to remain vigilant and heed official weather advisories for their safety and to mitigate potential hazards.
PAGASA indicates that the current cold surge might begin to weaken from Sunday, offering a preliminary signal for a shift in atmospheric patterns. The change in wind direction, a key indicator of seasonal transition, is anticipated in the coming days.
The warm and humid Easterlies, a different weather system characterized by warmer air from the Pacific, are expected to begin dominating by midweek next week. This shift typically ushers in higher temperatures and a reduction in rainfall, signaling the formal commencement of the warm and dry season.
The phenomenon of the Northeast Monsoon is characterized by cold, dry air originating from Siberia and mainland China. As this air mass travels across the Pacific Ocean, it picks up moisture before reaching the Philippines, resulting in the distinct cool and often rainy season experienced in many parts of the country from roughly October to March. This seasonal pattern is a fundamental element of the Philippine climate, deeply integrated into the cultural and agricultural rhythms of the archipelago.
Historically, the transition from the Amihan to the warm and dry season (often referred to as "tag-init" or summer) typically commences during the latter half of March, specifically around the third or fourth week. This year's persistent cold surge, extending past the typical onset of warming trends, marks a slight delay in this annual meteorological calendar, influencing everything from tourism plans to public health considerations related to respiratory illnesses. The timely and accurate forecasting by PAGASA is therefore crucial for national planning and public preparedness in a country regularly exposed to a spectrum of weather phenomena.
The sustained prevalence of the Amihan, even as the calendar advances towards spring, highlights the complex interplay of global weather patterns and local atmospheric conditions. For farmers dependent on predictable planting cycles, for fishermen whose livelihoods hinge on safe passage, and for urban dwellers adjusting their routines, understanding and adapting to these forecasts from PAGASA remains crucial. As the nation prepares to embrace warmer days, the lingering chill and occasional rains serve as a final, brisk reminder of the monsoon's seasonal embrace, prompting a careful watch for the definitive arrival of the dry season.
