Koror, Palau — Palau is likely to see more rain than usual from January to March 2025, according to the latest forecast from the Pacific Island Countries Advanced Seasonal Outlook (PICASO). Experts predict a 58% chance of above-normal rainfall during this time, driven by ongoing La Niña weather conditions.
Normally, January sees over 284 millimeters of rain, and the total for January through March averages more than 724 millimeters. With the forecast for extra rain, people in Palau may experience heavier downpours and wetter conditions than usual.
What’s Causing the Rain?
The weather is being influenced by La Niña, a climate pattern that happens when ocean waters in the central and eastern Pacific are cooler than normal. These cooler sea temperatures are expected to last through early 2025, gradually warming up by mid-year. La Niña often brings more rain and higher temperatures to Palau.
For the next several months, weather experts are also predicting warmer-than-usual temperatures alongside the extra rainfall.
How Reliable Is the Forecast?
The prediction is based on strong connections between past rainfall data in Koror and global weather patterns, such as ocean temperatures. Scientists are confident about this forecast, as their models show a clear link between La Niña conditions and more rain for Palau.
What Does This Mean for Palau?
With more rain expected, residents should prepare for potential problems like flooding, slippery roads, and landslides. Farmers could see benefits from extra water for crops but may also face challenges if heavy rains cause damage.
The monthly PICASO updates help people plan for the weather. The next forecast will come out in February, but residents can also get local weather updates from the National Weather Service Office in Palau.
