Air temperature trends, variability and extremes across the Solomon Islands: 1951-2011s

A significant warming trend has been observed across the Solomon Islands from 1951 to 2011, with mean annual temperatures rising by 0.14 to 0.39 °C per decade at seven weather stations. This shift is marked by an increase in warm days (2.2 days/decade) and warm nights (0.8 nights/decade), alongside a decrease in cool days (0.4 days/decade) and cool nights (1.4 nights/decade). The study, utilizing daily minimum and maximum temperature data from all operational stations, reveals that Taro has the highest mean temperature due to its equatorial proximity, while Henderson Island, part of UNESCO World Heritage Sites, recorded the lowest average at 26.9°C. Honiara's elevation contributes to its warmest temperatures during June through October. Overall, the Solomon Islands' climate has warmed significantly, with implications for regional ecosystems and heritage sites.
