PAGASA confirms La Niña, higher rainfall expected until February 2026

The Philippines is likely to experience higher than normal rainfall in the coming months as La Niña conditions have officially begun.

PAGASA confirmed the presence of La Niña on Friday, October 10, noting that cooler sea surface temperatures in the tropical Pacific began in August and met the La Niña threshold in September.

Climate models suggest this La Niña event could persist until at least February 2026.

The weather bureau forecasts that the increased rainfall will be most pronounced in the eastern parts of the country.

This phenomenon may lead to a higher chance of tropical cyclones entering the Philippine Area of Responsibility and other rain-generating weather systems, potentially causing floods and landslides.

The country has already experienced 17 tropical cyclones in 2025, and PAGASA projects that more may form before the year ends, exceeding the annual average of 20.
