The Southwest Monsoon — known locally as the Habagat — extended its grip over Northern and Central Luzon on Sunday, June 7, 2026, prompting the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) to issue a nationwide 24-hour weather forecast warning of scattered rains, thunderstorms, and the risk of flash floods and landslides across multiple regions. The forecast, issued at 4:00 AM and valid until 4:00 AM Monday, June 8, covers every part of the archipelago.
While the heaviest weather impact is concentrated in Luzon, no region of the country is entirely spared. PAGASA urges all Filipinos — from Batanes to Tawi-Tawi — to remain weather-aware throughout the day.
National Weather Picture: Monsoon Season Sets In
The Southwest Monsoon, a seasonal weather pattern that typically dominates the western side of the Philippines from June through September, is the primary driver of today's unsettled weather. As moisture-laden winds push in from the southwest, they interact with the country's mountainous terrain — particularly in Luzon — to produce significant cloud buildup, rain, and the threat of severe thunderstorms.
PAGASA's synopsis for June 7, 2026 is straightforward: the Southwest Monsoon is affecting Northern and Central Luzon. However, localized thunderstorms driven by daytime heating are expected to affect the rest of the country independently of the monsoon system itself.
Luzon: The Hardest-Hit Region
Ilocos Region: Occasional Rains Expected
In the northernmost reaches of Luzon's western coast, Ilocos Norte and Ilocos Sur are under the direct influence of the Southwest Monsoon. PAGASA forecasts occasional rains for these two provinces throughout the validity period. While the intensity is described as occasional rather than continuous, residents should remain cautious as brief but intense rain bursts are possible. Flash floods and landslides remain a concern whenever rainfall is sustained or heavy.
Metro Manila, CAR, and Central Luzon: Scattered Rains and Thunderstorms
A broader and more significantly affected zone stretches across a large swath of Luzon. Metro Manila — home to over 13 million residents — is forecast to experience cloudy skies with scattered rains and thunderstorms driven by the Southwest Monsoon. Commuters and outdoor workers in the capital should prepare for wet conditions that may intensify without much warning.
The same forecast applies to a wide belt of provinces: the Cordillera Administrative Region (CAR), which encompasses the highland provinces of Abra, Apayao, Benguet, Ifugao, Kalinga, Mountain Province, and Baguio City; and the lowland provinces of Pampanga, Bataan, Tarlac, Bulacan, Rizal, Cavite, and Batangas. The rest of the Ilocos Region — meaning La Union and Pangasinan — is also included in this outlook.
PAGASA specifically flags the possibility of flash floods or landslides due to moderate to at times heavy rains across this entire zone. Residents living near rivers, drainage channels, or steep hillsides are strongly advised to heed any local government advisories and be ready to evacuate if conditions deteriorate.

Visayas and Mindanao: Isolated Showers and Thunderstorms
For the Visayas and Mindanao — collectively described by PAGASA as "the rest of the country" — the forecast is comparatively more benign but not without risk. Partly cloudy to cloudy skies with isolated rain showers or thunderstorms are expected, caused by localized thunderstorms rather than the monsoon system directly.
This means that while sustained, widespread rain is less likely across the Visayas and Mindanao today, brief but powerful thunderstorms can develop rapidly in the afternoon and evening hours as the sun heats the land surface. PAGASA warns that even these localized systems carry the risk of flash floods or landslides during severe thunderstorms.
Residents in the Eastern Visayas, Western Visayas, Central Visayas, Zamboanga Peninsula, Northern Mindanao, Davao Region, SOCCSKSARGEN, BARMM, Caraga, and all other areas outside the Luzon monsoon belt should not dismiss today's forecast simply because it carries less alarming language. Localized thunderstorms can be sudden and intense, and their effects in low-lying or mountainous terrain can be just as dangerous.
Wind and Sea Conditions
Wind conditions today reflect the monsoon's dominance over the north. Northern and Central Luzon will experience moderate winds blowing from the southwest, consistent with the monsoon flow. Coastal waters in these areas are forecast to be moderate, with wave heights of 1.2 to 2.1 meters. Fisherfolk and small vessel operators in these waters are advised to exercise caution.
Across the rest of the country, winds will be light to moderate, blowing from the southeast to southwest. Coastal waters will be slight to moderate, with wave heights of 0.6 to 1.5 meters — generally manageable for most vessels, though small bancas should still proceed with care.
Temperature Outlook for Metro Manila
Based on readings recorded at the PAGASA Weather Station in Science Garden, Diliman, Quezon City, temperatures in Metro Manila for the 24-hour period ending 8:00 PM on June 6, 2026 ranged from a minimum of 25.3°C (recorded at 5:00 AM) to a maximum of 29.9°C (recorded at 2:00 PM). Relative humidity ranged from 71% to 93%, reflecting the muggy, moisture-saturated air typical of the monsoon season.
On cloudy, rainy days like today, maximum temperatures in Metro Manila may stay below the previous day's peak, though the combination of humidity and intermittent sunshine during breaks in the rain can still make conditions feel uncomfortable.
Tidal Information for Manila Bay
For those near coastal areas of Metro Manila, PAGASA — with tidal predictions courtesy of the National Mapping and Resource Information Authority (NAMRIA) — notes the following for Manila Bay on June 7, 2026: a high tide of 1.09 meters at 1:54 PM and a low tide of 0.05 meters at 10:39 PM. Coastal communities should factor in tidal conditions when assessing flood risks from rainfall runoff.
Sunrise, Sunset, and Moonrise
For reference, sunrise over Metro Manila is at 5:26 AM and sunset at 6:24 PM today. The moon will rise at 11:38 PM and set at 10:55 AM, with an illumination of 59% — a waxing gibbous phase.
Safety Advice for All Regions
Whether you are in monsoon-drenched Metro Manila or in Mindanao where only isolated thunderstorms are expected, PAGASA's hazard flags serve as a reminder that the rainy season demands heightened caution. Here is what Filipinos across the country should keep in mind today:
Avoid flood-prone areas. Even a short but heavy downpour can cause rapid flooding in low-lying neighborhoods, underpasses, and near riverbanks. Do not attempt to cross flooded roads or bridges on foot or by vehicle.
Watch for landslide warnings. Those living near slopes, mountains, or hillside communities — especially in CAR, Ilocos, and Rizal — should stay alert for any signs of ground movement or soil saturation after prolonged rain.
Secure loose items. Thunderstorms can bring sudden, strong winds. Secure rooftop items, signboards, and outdoor furniture before storms approach.
Do not travel unnecessarily during heavy rain. If your area is under a thunderstorm, wait for conditions to improve before traveling, especially on mountain roads or coastal routes.
Keep communication lines open. Local government units may issue supplementary advisories specific to your municipality or city. Stay tuned to local radio, television, and official social media channels.
Stay Updated with PAGASA
Weather conditions during the monsoon season can shift rapidly. The forecast issued at 4:00 AM on June 7, 2026 is valid until 4:00 AM on June 8, 2026, but PAGASA may issue updated bulletins throughout the day as the situation evolves. All Filipinos are encouraged to check for the latest advisories regularly.
