CAGAYAN DE ORO CITY, June 12, 2026 — Residents across Mindanao should remain alert as localized thunderstorms are expected to affect various parts of the island over the next 24 hours, according to the latest regional weather forecast issued by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) Mindanao Regional Services Division (MINPRSD).
In its 5:00 a.m. weather bulletin on Friday, PAGASA said Mindanao will experience partly cloudy to cloudy skies with isolated rain showers and thunderstorms caused by localized thunderstorm activity.
While much of the region will continue to experience generally fair weather conditions, forecasters warned that severe thunderstorms may trigger flash floods and landslides, particularly in low-lying, flood-prone, and mountainous areas.
“Possible flash floods or landslides may occur during severe thunderstorms,” PAGASA stated in its advisory.
Rain Showers Expected Across All Mindanao Regions
The forecast covers the Zamboanga Peninsula, Northern Mindanao, Davao Region, SOCCSKSARGEN, Caraga Region, and the Bangsamoro Autonomous Region in Muslim Mindanao (BARMM), all of which are expected to experience similar weather patterns.
Areas in the Zamboanga Peninsula, including Zamboanga City, Zamboanga del Norte, Zamboanga del Sur, Zamboanga Sibugay, and Isabela City, are forecast to have partly cloudy skies becoming cloudy at times with rain showers and thunderstorms. Temperatures are expected to range from 24°C to 34°C.
In Northern Mindanao, provinces such as Bukidnon, Camiguin, Lanao del Norte, Misamis Occidental, and Misamis Oriental will also experience isolated thunderstorms. Bukidnon is expected to record some of the coolest temperatures in the region, ranging from 19°C to 32°C.
The Davao Region, including Metro Davao, Davao del Norte, Davao del Sur, Davao Oriental, Davao de Oro, and Davao Occidental, is likewise expected to experience intermittent rain showers and thunderstorms. Temperatures across the region may reach as high as 34°C, especially during sunny periods.
Meanwhile, in SOCCSKSARGEN, North Cotabato is forecast to experience one of the highest daytime temperatures in Mindanao, reaching up to 35°C, while South Cotabato, Sultan Kudarat, and Sarangani will also see warm conditions accompanied by isolated thunderstorms.
The Caraga Region, including Agusan del Norte, Agusan del Sur, Surigao del Norte, Surigao del Sur, and Dinagat Islands, will continue to experience unstable weather conditions. Maximum temperatures may climb to 35°C in some areas, particularly in Agusan del Norte and Dinagat Islands.
Similarly, provinces under the BARMM, including Basilan, Sulu, Tawi-Tawi, Lanao del Sur, Maguindanao del Norte, Maguindanao del Sur, and Cotabato City, are forecast to experience partly cloudy to cloudy skies with occasional thunderstorms throughout the forecast period.
Coastal Conditions Remain Favorable
PAGASA reported that winds across Mindanao will generally be light to moderate, coming from the southeast to south.
Sea conditions along the coastal waters of Mindanao are expected to remain slight to moderate, with wave heights ranging from 0.6 to 1.5 meters, making conditions generally safe for most small fishing vessels and sea travel. However, authorities advised fishermen and operators of small boats to remain cautious during thunderstorm activity, which may bring sudden strong winds and rough seas.
Public Advised to Stay Alert
Weather experts emphasized that localized thunderstorms can develop rapidly and may produce intense rainfall within a short period, increasing the risk of flooding, particularly in areas still recovering from recent natural disasters and soil instability.
Local disaster risk reduction offices are encouraging residents to monitor weather updates, avoid crossing flooded roads and rivers, and immediately seek shelter when thunderstorms occur.
PAGASA continues to monitor weather conditions across Mindanao and advised the public to stay informed through official forecasts and advisories for any significant changes in weather patterns.
The forecast remains valid from 5:00 a.m. on June 12 until 5:00 a.m. on June 13, 2026.
