DUMAGUETE CITY, Negros Oriental — Sunday, October 25, 2026 will be a wet one for Negros Oriental, with the state weather bureau PAGASA issuing a forecast of cloudy skies, rainshowers, and thunderstorms that are expected to persist from early morning through the overnight hours across the province — including coastal areas and the island of Siquijor.
Daytime Forecast: Cloudy with Rain and Thunder
PAGASA’s regional forecast, issued at 5:00 AM on October 25, 2026, projects cloudy skies with rainshowers and thunderstorms over Negros Oriental from 5:00 AM through 5:00 PM. Daytime temperatures will range between 25°C and 31°C. Winds are expected to blow from the southwest to northwest during the morning and afternoon hours.
Overnight Outlook: Rain Chances Persist
From 5:00 PM on Sunday through 5:00 AM on Monday, October 26, PAGASA says conditions will shift to partly cloudy to at times cloudy skies, with rainshowers or thunderstorms remaining possible. Overnight temperatures will ease slightly to a range of 25°C to 29°C, and winds will rotate to a northwest to northeast direction.
Weather System Behind the Conditions
The PAGASA forecast data does not attribute Sunday’s unsettled weather to a single named weather system. The combination of a wind direction shift — from southwest-northwest in the daytime to northwest-northeast overnight — alongside persistent cloud cover and thunderstorm activity indicates an unsettled atmospheric pattern over the Visayas. PAGASA’s official advisories remain the authoritative source for any updated system attribution.
Siquijor and Coastal Waters Also Affected
The wet weather pattern extends beyond the Negros Oriental mainland. Siquijor, located south of Dumaguete across the Tanon Strait, will experience the same cloudy and rain-prone conditions throughout Sunday, according to the PAGASA forecast. Coastal waters in the area are rated slight to moderate for both daytime and overnight periods — conditions that are generally manageable for large commercial vessels but can be uncomfortable and hazardous for smaller craft, especially when thunderstorms are also present.
No Active Wind Signal or Rainfall Warning Raised
PAGASA’s bulletin carries no active tropical cyclone wind signal and no formal rainfall warning — such as a yellow, orange, or red alert — for Negros Oriental at the time of issuance. However, the agency’s thunderstorm forecast carries practical implications: lightning, sudden strong wind gusts, and brief episodes of locally heavy rainfall can occur even without a formal warning level in effect.
Guidance for Travelers and Ferry Passengers
Travelers moving along Negros Oriental’s coastal highway — from Dumaguete south toward Bayawan or north toward Bais and Guihulngan — should prepare for wet road surfaces and reduced visibility during heavy rain bursts. Passengers booked on inter-island routes between Dumaguete, Siquijor, Tagbilaran, and Cebu, including services operated by lines such as OceanJet, are advised to check with their shipping operators before departure, as slight-to-moderate seas combined with possible thunderstorms may affect sailing schedules. Boarding small, open bancas or outrigger boats for inter-island crossings is not advised under these conditions.
Fisherfolk and Small Boat Operators
PAGASA’s slight-to-moderate coastal water rating, combined with the threat of thunderstorms, creates hazardous conditions for small fishing vessels and bancas operating out of Dumaguete, Bayawan, Bais, and other Tanon Strait communities. Lightning at sea poses a serious and immediate danger. Fisherfolk who must go out are advised to stay close to shore in familiar waters and return to port before any storm develops.
Farmers, Outdoor Workers, and Other Groups
Farmers in agricultural areas such as the Guihulngan valley and the lowlands around Bais and Bayawan face disrupted field work due to prolonged rain and thunderstorm activity, with waterlogging a risk in low-lying fields. Outdoor and construction workers are advised to suspend work in exposed areas during thunderstorm episodes, as lightning poses a direct hazard to workers on scaffolding or in open terrain. Families are advised to keep children indoors during periods of active thunderstorm activity, particularly in the afternoon when convective storms tend to intensify.
Temperature Notes
Despite the unsettled conditions, PAGASA’s temperature forecast is not drastically cool. The daytime range of 25°C to 31°C means humid warmth will accompany the rain showers, while the overnight range of 25°C to 29°C offers moderate cooling. The elderly and young children may be particularly affected by the combination of heat and sudden downpours.
