Expect more rainy days in the next five months, as well as possible tropical cyclones, in Catanduanes, the Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA) said in its Climate Outlook for the period September 2025 to February 2026.
In the report presented by Ana Liza S. Solis of the Climate Monitoring and Prediction Section, the island province will have above-average rainfall from September 2025 to January 2026, followed by near normal rainfall in February 2026.
The predicted maximum precipitation for said months are the following: September, 318mm; October, 476.4 mm; November, 447.4 mm; December, 648.8 mm; January, 358 mm; and February, 183.4 mm.
From 15 days this month, the number of dry days (with less than 1 mm of rainfall observed) will drop to 13 next month, 11 in November, and 12 in December, the first two months of 2026 predicted to have 16 dry days each.
PAGASA said that a short-lived La Niña is forecast to occur conditions as early as the September
October-November season until the October-November-December season.
It may not develop into a full blown La Niña; but significant impacts may be experienced and may vary in different areas, it stressed.
Among the possible impacts of the looming La Niña conditions include the development of tropical cyclones near or inside the Philippine Area of Responsibility (PAR); more tropical cyclone occurrences during the last quarter of the year based on past histories of weak La Niña; and, higher probability of above normal rainfall, with some areas forecast to have above normal rainfall highly vulnerable to floods and landslides.
It disclosed that between seven (7) to 15 tropical disturbances are likely to develop or enter the PAR during the period: September, 2 to 4; October, 2 to 4; November, 2 or 3; December, 1 or 2; January, 0 or 1; and February, 0 or 1.
