CAGAYAN DE ORO CITY – Residents across Mindanao should prepare for another day of cloudy skies, scattered rain showers, and thunderstorms as the Southwest Monsoon (Habagat) continues to affect the entire island, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
In its Regional Weather Forecast for MINPRSD, issued at 5:00 a.m. on Wednesday, July 22, 2026, PAGASA said the forecast remains valid until 5:00 a.m. Thursday, July 23, with the prevailing Southwest Monsoon expected to bring moderate to at times heavy rainfall, increasing the risk of flash floods and landslides, particularly in low-lying communities, flood-prone areas, and mountainous terrain.
Authorities are urging residents to remain vigilant, especially those living near rivers, creeks, and landslide-prone slopes, as intermittent heavy downpours may occur throughout the day and overnight.
Rainy Conditions to Persist Across Mindanao
Virtually the entire Mindanao island is forecast to experience cloudy skies with scattered rain showers and thunderstorms, with no region expected to enjoy prolonged fair weather.
PAGASA also reported light to moderate winds blowing from the southwest to west, while coastal waters across most seaboards will remain slight to moderate, with wave heights ranging from 0.6 to 1.5 meters, making sea travel generally manageable but still requiring caution during thunderstorms.
Zamboanga Peninsula
Residents in Zamboanga City, Zamboanga del Norte, Zamboanga del Sur, Zamboanga Sibugay, and Isabela City can expect cloudy skies accompanied by frequent rain showers and thunderstorms.
Daytime temperatures are forecast to range between 29°C and 32°C, while nighttime temperatures will remain between 24°C and 25°C.
Northern Mindanao
The provinces of Bukidnon, Camiguin, Lanao del Norte, Misamis Occidental, and Misamis Oriental will continue to experience overcast skies with scattered rains.
Bukidnon is expected to record one of the coolest temperatures in the region, ranging from 20°C to 30°C, while coastal provinces may reach highs of 31°C to 32°C.
Davao Region
Across Metro Davao, Davao del Norte, Davao del Sur, Davao Oriental, Davao de Oro, and Davao Occidental, widespread rain showers and thunderstorms are expected to persist throughout the forecast period.
Temperatures will generally range from 23°C to 32°C, with Davao Occidental likely experiencing slightly cooler conditions due to persistent cloud cover.
SOCCSKSARGEN
The provinces of North Cotabato, South Cotabato, Sultan Kudarat, and Sarangani will likewise experience cloudy weather with intermittent rains and thunderstorms.
Maximum temperatures across the region are expected to range between 31°C and 32°C, while minimum temperatures will remain between 23°C and 25°C.
Caraga Region
Residents in Agusan del Norte, Agusan del Sur, Surigao del Norte, Surigao del Sur, and Dinagat Islands should also anticipate unstable weather conditions.
Among all provinces, Agusan del Sur is forecast to be among the warmest, with temperatures reaching up to 33°C, despite the expected rainfall.

The Southwest Monsoon will also continue to affect Cotabato City, Basilan, Lanao del Sur, Sulu, Tawi-Tawi, Maguindanao del Norte, and Maguindanao del Sur.
Lanao del Sur is expected to record the coolest temperatures in BARMM, with lows of 22°C, while the rest of the region will experience temperatures ranging between 23°C and 32°C.
Public Advisory
PAGASA advised the public to monitor official weather bulletins and remain alert for possible flooding, landslides, and sudden thunderstorms that could affect transportation, agriculture, fishing activities, and outdoor operations.
Motorists are encouraged to exercise extra caution on slippery roads, while fishermen and operators of small sea vessels are advised to remain vigilant, especially during thunderstorms, despite generally slight to moderate sea conditions.
Local Disaster Risk Reduction and Management Offices (LDRRMOs) are likewise urged to closely monitor vulnerable communities and be prepared for possible emergency response operations should heavy rainfall trigger flooding or landslides.
The Southwest Monsoon remains the dominant weather system affecting Mindanao, and weather authorities continue to remind the public that localized thunderstorms may produce sudden heavy rainfall, strong winds, and lightning even in areas not initially experiencing rain.
