Solomon Islands Sea Surface Temperature Anomaly

Sea surface temperatures over Solomon Islands reefs show a clear long-term warming trend, with anomalies increasingly above the historical baseline since the mid-1980s. Reef waters are therefore more often exposed to positive temperature anomalies linked to coral bleaching risk. Pacific reef waters around the Solomon Islands were about 0.82 °C warmer in 2022 than in 1990, with recent anomalies of around +0.8 °C to +1.2 °C creating thermal stress conditions. Despite this, Solomon Islands reefs remain relatively resilient, often maintaining high live coral cover and diversity at surveyed sites (Denley, Metaxas and Scheibling, 2020). 

Average Sea Surface Temperature (SST) anomaly from 1985 to 2023 over coral reefs of Solomon Islands. The black line is the long-term trend in SST anomaly, values below this line are negative SST anomalies (i.e. cooler than long-term trend), and values above this line are positive SST anomalies (i.e. warmer than long-term trend). Derived from NOAA Coral Reef Watch data (https://coralreefwatch.noaa.gov/) for the GRCMN report (Wicquart et al., 2025)
