A weak La Niña pattern is anticipated to affect Fiji’s weather until early 2026, bringing wetter-than-normal conditions across much of the country, according to the Fiji Meteorological Service. This phenomenon in the tropical Pacific Ocean is expected to transition to neutral conditions in the coming years.
The service highlights that January is projected to experience above-average rainfall throughout the Western and Central divisions. Meanwhile, the Northern and Eastern divisions, along with Rotuma, are expected to see normal to above-normal precipitation. From January to March, most areas in the Fiji Group are likely to receive above-normal rainfall, with Rotuma also forecasted for similar precipitation levels.
Looking ahead to the April to June period, the forecast becomes less certain, indicating equal probabilities of below-average, normal, or above-average rainfall, suggesting potential variability tied to regional weather patterns. There is also an increased risk of tropical systems, with one to two tropical cyclones expected to impact Fiji this season. Even minor tropical disturbances could result in significant rainfall during this period.
In terms of temperatures, they are expected to remain above normal, especially through January and March, with both maximum and minimum temperatures predicted to exceed typical levels. The Fiji Meteorological Service reports that La Niña conditions often correlate with heightened rainfall, particularly during the wet season.
In response to these forecasts, local authorities are advising communities, farmers, and businesses to prepare for potential heavy rainfall, flooding, and rising temperatures in the months ahead. Emphasizing the need to stay informed through official weather updates, they aim to mitigate the effects of extreme weather conditions and enhance safety across the region. This proactive stance can foster resilience and preparedness among the population as they navigate through the expected climatic challenges.
