A weak La Niña pattern is set to influence Fiji’s weather conditions into early 2026, leading to wetter-than-normal conditions across much of the nation, as reported by the Fiji Meteorological Service. This ongoing phenomenon within the tropical Pacific Ocean is expected to gradually transition to neutral conditions in the following years.
The service indicates that January is likely to see above-average rainfall throughout the Western and Central divisions, with the Northern and Eastern divisions, as well as Rotuma, anticipated to experience normal to above-normal precipitation. The forecast from January to March suggests that most areas in the Fiji Group will witness above-normal rainfall, while Rotuma is similarly expected to receive normal to above-normal rainfall totals.
As forecasters look ahead to the April-June period, the prediction becomes less definitive, with equal chances of below, normal, or above-average rainfall, suggesting potential variability depending on evolving regional weather patterns. Additionally, there is a heightened risk of tropical systems, with expectations of one to two tropical cyclones affecting Fiji this season. Even minor tropical disturbances or depressions could lead to significant increases in rainfall during this outlook period.
Temperatures will likely remain warmer than usual, particularly through January and into March, with both maximum and minimum temperatures expected to exceed normal levels. The Fiji Meteorological Service notes that typically, La Niña conditions contribute to increased rainfall, especially during the wet season.
In light of these forecasts, local authorities are urging communities, farmers, and businesses to prepare for possible heavy rainfall, flooding, and increased temperatures in the coming months, while emphasizing the importance of staying updated through official weather channels. This proactive approach can help mitigate the impacts of extreme weather conditions and ensure safety across the region.
