Understanding trends in rainfall and temperature extremes is critical for evaluating their impacts on ecosystems, agriculture, water resources, human livelihoods, and health, especially in vulnerable regions like Fiji. This study analysed rainfall and temperature extremes in Fiji from 1970–2020 using the Mann-Kendall trend test, Innovative Trend Analysis, and Theil-Sen’s slope estimator. Results indicated a general decrease in annual, seasonal, and monthly rainfall, with notable declines in the months of November, March, July, and August, and an increase in December. Rainfall extremes showed decreasing trends across most stations, except Nadi, which exhibited an increase. Temperature trends show a consistent and significant increase in both maximum and minimum temperatures, with warming rates ranging from 0.01–0.05°C per year. Temperature extremes revealed a significant warming trend, with increases in extreme indices such as the hottest day (TXx), warmest night (TNx), and warm days (TX90p), alongside decreases in cool days (TX10p), cool nights (TN10p), and cold spell duration (CSDI). These findings underscore the growing challenges of climate extremes in Fiji and provide essential data for informing adaptation and mitigation strategies.
