The Fiji Meteorological Service’s 2024 Annual Climate Summary highlights a persistent warming trend in Fiji, pointing to the ongoing effects of climate change. Since 1959, the country’s national average maximum air temperature has increased by 1.2°C, and the average minimum temperature has risen by 1.0°C. These changes are statistically significant at the 95% confidence level, indicating the profound impact of global warming in the region.
In 2024, Keiyasi recorded the highest annual mean maximum air temperature at 34.5°C. Other high temperatures were seen at RKS Lodoni (32.5°C), Viwa (32.0°C), Yaqara (31.5°C), and Lautoka Mill (31.1°C). Monasavu recorded the coolest annual mean maximum temperature at 24.8°C, with Nadarivatu following at 27.7°C. These temperatures reveal significant variations across Fiji.
The hottest day was February 26 at RKS Lodoni, where the temperature reached 37.8°C. Meanwhile, Viwa registered the highest annual average minimum temperature at 25.1°C. Monasavu again reported the lowest average minimum for night-time temperatures at 18.7°C, with Nadarivatu at 20.2°C. The lowest temperature of the year, 10.9°C, was recorded in Nadarivatu on August 7.
These findings underscore the marked shifts in Fiji’s climate, reflecting global trends driven by rising greenhouse gas concentrations. Past reports, such as in 2023, have consistently noted increasing temperatures over decades, underscoring the need for heightened environmental awareness and strategic climate adaptation policies. These data highlight the urgency for strong measures to combat climate change and encourage innovation in sustainable practices to improve community resilience and environmental protection.
While the rising temperatures present challenges, they also create opportunities for transformative approaches to climate resilience and sustainable development in Fiji. By using the insights gained from these reports, stakeholders can more effectively plan and implement strategies to adapt to a changing climate, fostering a sustainable future.
