Filipinos across the archipelago can expect partly cloudy skies with the possibility of isolated thunderstorms today, as weather patterns continue to be influenced by a high pressure system over Luzon and persistent easterly winds affecting the central and southern regions of the country.
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) issued its forecast at 4:00 AM today, April 23, 2026, indicating that weather conditions will remain generally stable but with localized rain possibilities, particularly during afternoon and evening hours.
High Pressure Ridge Affects Northern Philippines
According to PAGASA's weather analysis, a ridge of high pressure area (HPA) extending over the eastern sections of Northern and Central Luzon is the dominant weather feature affecting the northern part of the country. This weather pattern typically brings more stable atmospheric conditions and reduced rainfall activity.
Meanwhile, easterlies – warm, moist winds coming from the Pacific Ocean – continue to influence weather patterns over Southern Luzon, the entire Visayas region, and Mindanao. These easterly winds often trigger the development of localized thunderstorms, especially during the warmer afternoon hours.
Regional Weather Outlook
Northern and Central Luzon
Residents in Northern and Central Luzon, including Metro Manila and surrounding provinces, can expect partly cloudy to cloudy skies throughout the day. The high pressure ridge will generally suppress widespread rainfall, though isolated light rains or thunderstorms may still develop in some areas.
The weather bureau notes that any thunderstorms that do form in these regions will likely be brief and localized, with most areas experiencing dry conditions for the majority of the day.
Southern Luzon
Southern Luzon provinces will experience partly cloudy to cloudy skies with isolated thunderstorms expected. The easterly wind pattern affecting this region increases the likelihood of afternoon and evening thunderstorm development, particularly in areas near mountain ranges where orographic lifting can enhance cloud formation.
Visayas Region
The Visayas region will see similar weather patterns to Southern Luzon, with partly cloudy to cloudy skies and isolated thunderstorms possible. Island provinces should be prepared for brief but potentially intense rainfall during thunderstorm activity.
Mindanao
Mindanao will experience partly cloudy to cloudy conditions with isolated thunderstorms expected, particularly during afternoon hours when atmospheric heating is at its peak. The easterly winds will continue to provide moisture that can fuel thunderstorm development across the island.
Wind and Coastal Conditions
Wind conditions across the Philippines will remain generally favorable for most activities. Northern and Central Luzon will experience light to moderate winds coming from the northeast direction, while the rest of the country can expect light to moderate easterly winds.
Coastal waters nationwide will remain slight to moderate, with wave heights posing minimal risk to maritime activities. Small watercraft operators should still exercise normal precautions, particularly during thunderstorm activity when winds may temporarily increase and sea conditions can become choppy.
Temperature Outlook
Based on PAGASA's monitoring data, temperature conditions remain within normal ranges for this time of year. Yesterday's temperature readings in Metro Manila showed a maximum of 35.5°C recorded at 5:00 PM and a minimum of 22.7°C at 6:00 AM, indicating typical April weather patterns for the Philippines.
Relative humidity levels also remained within expected parameters, ranging from a maximum of 91% in early morning hours to a minimum of 32% during the afternoon peak heating period.
Safety Reminders and Precautions
While today's weather forecast indicates generally manageable conditions, PAGASA reminds the public to remain vigilant during thunderstorm activity. Isolated thunderstorms, though brief, can still produce hazardous conditions including:
Flash flooding in low-lying and flood-prone areas, particularly in urban centers with poor drainage systems. Residents in these areas should avoid walking or driving through flooded streets and remain indoors during heavy downpours.
Possible landslides in mountainous and hilly terrain, especially in areas with unstable soil conditions or previous landslide activity. Communities in these locations should monitor weather conditions closely and be prepared to evacuate if necessary.
Lightning strikes during thunderstorm activity pose risks to outdoor activities. The public is advised to seek shelter indoors and avoid open areas, tall structures, and bodies of water when thunder and lightning are present.
Extended Outlook
The current weather pattern of high pressure influence over Northern Luzon and easterly wind dominance over the rest of the country is expected to persist in the near term. This suggests that similar weather conditions – partly cloudy skies with isolated thunderstorm possibilities – will likely continue over the coming days.
Residents and local government units should continue monitoring official weather updates, particularly as seasonal weather patterns can shift with little warning during this time of year.
"The ridge of high pressure area extending over eastern sections of Northern and Central Luzon, combined with easterlies affecting Southern Luzon, Visayas, and Mindanao, will continue to be the primary drivers of our current weather patterns," according to PAGASA's latest forecast discussion.
