The Southwest Monsoon — locally known as Habagat — is asserting its presence across the Philippines this Tuesday, June 2, 2026, bringing cloudy skies, scattered rainfall, and the risk of flash floods and landslides to large portions of Luzon and the western edge of the Visayas. PAGASA issued its 24-hour public weather forecast at 4:00 AM today, with the bulletin valid until 4:00 AM on Wednesday, June 3.
While Mindanao and the eastern sections of the country face a comparatively calmer weather picture, residents across the western seaboard of the Philippines — from the Ilocos coastline down through Manila Bay's provinces and into Western Visayas — are advised to remain alert for rainfall that could trigger dangerous flooding and landslides in low-lying and mountainous communities.
National Weather Overview
PAGASA identifies the Southwest Monsoon as the primary weather system currently affecting the country. The monsoon is driving moisture-laden winds from the southwest into the western coastal areas of Luzon and has extended its influence into the western portion of the Visayas. The remainder of the Philippines is experiencing weather largely shaped by localized thunderstorm activity rather than a large-scale weather system.
Across the board, PAGASA has flagged the risk of flash floods and landslides — varying by area — as the chief public safety concern for the day. Residents living near rivers, creeks, and hillside communities are urged to stay informed and heed advisories from local disaster risk reduction offices.
Luzon Forecast
Zambales, Bataan, Cavite, Batangas, and Occidental Mindoro
These five provinces bear the brunt of the Southwest Monsoon's direct impact today. PAGASA forecasts occasional rains over these areas, with the agency explicitly warning of possible flash floods or landslides due to moderate to heavy rainfall. Residents in coastal and upland barangays in these provinces should monitor river levels and drainage conditions throughout the day.
Occidental Mindoro, situated along the western facing coastline of Luzon, is particularly exposed to southwest wind-driven rainfall, and communities in hilly terrain should be on heightened alert. In Batangas and Cavite, where suburban and rural communities sit alongside river systems draining from mountainous interiors, the flash flood warning warrants close attention from local government units.
Metro Manila and the Rest of Luzon
Metro Manila residents should expect a wet Tuesday. PAGASA forecasts cloudy skies with scattered rains and thunderstorms for the capital region and the remainder of Luzon, with the Southwest Monsoon again identified as the driving force. Moderate to at times heavy rains are possible, and PAGASA maintains the warning for potential flash floods and landslides.
This forecast covers a wide swath of Luzon beyond Metro Manila — from the Ilocos Region and Cordillera Administrative Region in the north, through Central Luzon, CALABARZON, MIMAROPA, and the Bicol Region in the south. Commuters and motorists across this broad area should anticipate reduced visibility during heavy rain episodes and possible flooding of low-lying roads and underpasses.
For Extreme Northern Luzon — covering the northernmost portions of Ilocos Norte and Cagayan, including the Batanes and Babuyan island groups — PAGASA forecasts moderate winds blowing from the southwest. Coastal waters in this zone will be moderate, with wave heights of 1.2 to 2.5 meters. Mariners and fishing communities in this area should exercise caution.
Visayas Forecast
Western Visayas
Western Visayas — encompassing Iloilo, Capiz, Aklan, Antique, Guimaras, and Negros Occidental — falls under the direct influence of the Southwest Monsoon alongside Metro Manila and the rest of Luzon. The region can expect cloudy skies with scattered rains and thunderstorms, with moderate to at times heavy rainfall possible. PAGASA warns of flash flood and landslide risks here as well, particularly in the mountainous interior of Negros Occidental and Iloilo's eastern highlands.
The Rest of Visayas
Eastern Visayas and the remainder of the Visayas island group — including Cebu, Bohol, Leyte, Samar, Negros Oriental, and Siquijor — are not under the direct influence of the Southwest Monsoon today. Instead, these areas will see partly cloudy to cloudy skies with isolated rainshowers or thunderstorms, produced by localized convective activity. Flash floods remain a possibility during particularly intense or severe thunderstorm episodes. While overall conditions are less severe than in the west, residents should not disregard the potential for sudden, intense local downpours.
Mindanao Forecast
Mindanao as a whole falls under the "rest of the country" category in today's PAGASA bulletin, meaning the island group will experience partly cloudy to cloudy skies with isolated rainshowers or thunderstorms driven by localized thunderstorm activity. This applies to all major regions of Mindanao — Davao Region, Northern Mindanao, the Zamboanga Peninsula, SOCCSKSARGEN, Caraga, and the Bangsamoro Autonomous Region in Muslim Mindanao.
While the threat level is lower than that faced by western Luzon and Western Visayas, PAGASA still cautions that flash floods are possible during severe thunderstorms. Communities near rivers and in low-lying areas across Mindanao should remain alert to rapidly changing conditions throughout the day.
Temperature and Humidity
For reference, PAGASA's weather station at Science Garden in Diliman, Quezon City recorded a maximum temperature of 30.4°C at 3:00 PM yesterday, with a minimum of 25.7°C at 5:00 AM. Relative humidity ranged from a high of 94 percent to a low of 75 percent over the same 24-hour period ending at 8:00 PM yesterday. These figures reflect the warm and humid conditions typical of southwest monsoon season.
Wind and Coastal Water Conditions
PAGASA divides wind and sea conditions into two zones for today's forecast. Over Extreme Northern Luzon, winds are moderate in intensity, blowing from the southwest, with coastal waters running moderate and wave heights reaching 1.2 to 2.5 meters. Fishing vessels and small watercraft operating in these northern waters should exercise appropriate caution.
Over the rest of the country, winds are light to moderate in intensity, blowing from the southeast to southwest, with coastal waters classified as slight to moderate — wave heights between 0.6 and 2.5 meters. Mariners nationwide should check conditions before putting out to sea, particularly given the active monsoon environment.
Astronomical Information for Metro Manila
Sunrise over Metro Manila today is at 5:26 AM, with sunset at 6:22 PM. The moon rises at 8:08 PM and sets at 6:36 AM, with an illumination of 96 percent — effectively a near-full moon. Tidal information for Manila Bay, courtesy of NAMRIA, indicates a high tide of 1.23 meters at 10:25 AM and a low tide of -0.16 meters at 7:18 PM.
Safety Reminders
PAGASA's flash flood and landslide warnings should be taken seriously by residents across the flagged areas. If you live near a river, creek, or hillside — particularly in the provinces of Zambales, Bataan, Cavite, Batangas, and Occidental Mindoro — stay alert to rising water levels and be ready to evacuate if instructed by local authorities. The same applies to communities in Metro Manila and Western Visayas that are prone to street flooding during heavy monsoon rains.
Motorists should drive carefully in low-visibility conditions, avoid flooded roads, and follow advisories from local disaster risk reduction and management councils. Residents in coastal communities should monitor sea conditions before engaging in maritime activities.
Today's 24-hour public weather forecast was issued by PAGASA at 4:00 AM on Tuesday, June 2, 2026, and is valid until 4:00 AM on Wednesday, June 3, 2026. The forecast was prepared by VCT and checked by ADA of the PAGASA Weather and Flood Forecasting Center, Quezon City.
