The state weather bureau forecasts cloudy to partly cloudy conditions nationwide today, with scattered thunderstorms likely to develop across various regions as atmospheric patterns remain under the influence of easterly winds and a high pressure ridge system.
PAGASA released its weather advisory at 4:00 AM this April 23, 2026, warning of potential thunderstorm activity particularly during late afternoon and evening periods when atmospheric instability typically peaks across the archipelago.
Atmospheric Systems Shape Current Weather
Meteorological analysis reveals that easterly winds – moisture-laden air currents originating from the Pacific Ocean – are the primary weather influence affecting Southern Luzon, the Visayas, and Mindanao regions. These wind patterns commonly generate localized convective activity that manifests as thunderstorms during peak heating hours.

Simultaneously, a high pressure area ridge positioned over eastern portions of Northern and Central Luzon continues to dominate weather conditions in the northern regions. This system generally promotes atmospheric stability while limiting extensive precipitation coverage.
Temperature and Humidity Readings
Yesterday’s meteorological observations in Metro Manila recorded temperature extremes typical for the current season. The mercury peaked at 35.5°C during 5:00 PM and dropped to its lowest point of 22.7°C at 6:00 AM, reflecting normal April temperature variations for the Philippines.
Humidity measurements fluctuated significantly throughout the day, reaching 91% during early morning hours before declining to 32% during afternoon’s peak heating phase, demonstrating the typical daily moisture cycle.
Area-Specific Weather Predictions
Luzon’s Northern and Central Areas
Metro Manila and surrounding northern provinces will encounter cloudy to partly cloudy conditions throughout the day. The prevailing high pressure ridge will generally inhibit widespread rainfall development, although isolated precipitation or brief thunderstorms may occur in scattered locations.
Weather forecasters indicate that any storm activity developing in these areas will typically be short-duration and geographically limited, with most locations remaining predominantly dry.
Southern Luzon Provinces
Areas south of Manila will experience cloudier skies with higher probabilities of isolated thunderstorm development. The easterly flow pattern increases atmospheric moisture content, particularly enhancing storm potential near mountainous terrain where topographic lifting accelerates cloud formation processes.
Visayas Islands
Central Philippine islands will encounter weather conditions similar to Southern Luzon, featuring cloudy to partly cloudy skies with thunderstorm possibilities. Provincial areas should anticipate brief but potentially heavy rainfall episodes during active thunderstorm periods.
Mindanao Island
The country’s southernmost major island will see cloudy to partly cloudy weather with isolated thunderstorms anticipated, especially during afternoon hours when solar heating reaches maximum intensity. Easterly moisture transport will continue supporting thunderstorm development across the region.
Maritime and Wind Conditions
Wind patterns nationwide will maintain generally moderate characteristics suitable for most outdoor activities. Northern and Central Luzon areas will experience light to moderate northeasterly winds, while remaining regions can expect light to moderate easterly wind flow.
Sea conditions around Philippine waters will remain slight to moderate, presenting minimal hazards to maritime operations. However, small vessel operators should maintain standard safety protocols, especially during thunderstorm periods when temporary wind intensification and rougher seas may develop.
Public Safety Guidelines
Despite the generally stable weather outlook, PAGASA emphasizes the importance of thunderstorm preparedness. Even isolated storm systems can create dangerous conditions including rapid flooding in poorly-drained urban areas and low-lying communities. Citizens should avoid traversing flooded roadways and remain indoors during intense rainfall.
Mountain communities face potential landslide risks, particularly in locations with unstable soil or previous slope failure history. Local residents should closely monitor weather developments and maintain evacuation readiness when conditions warrant.
Lightning hazards during thunderstorms require avoiding outdoor activities, open spaces, elevated structures, and water bodies when electrical activity is present. Indoor shelter provides the safest protection during storm passage.
Extended Weather Perspective
Current meteorological patterns featuring high pressure influence over northern territories and easterly dominance elsewhere are forecast to continue in coming days. This suggests similar weather characteristics – partly cloudy conditions with scattered thunderstorm potential – will persist through the immediate forecast period.
Citizens and emergency management authorities should maintain awareness of official weather communications, as seasonal transition periods can produce rapid atmospheric changes during this time of year.
“Current weather drivers include the high pressure ridge over eastern Northern and Central Luzon sections, while easterlies continue affecting Southern Luzon, Visayas, and Mindanao,” stated PAGASA in their forecast discussion.
