(A) Sea surface temperature values of the Caribbean Sea from NOAA buoy data. The values for San Andrés Island are from the years 2009 and 2020 (from buoy 42057), compared to the average Caribbean Sea data. (B) Sea surface temperature anomaly data from the NOAA Global Time Series dataset given for the location of San Andrés, the Caribbean Island (as defined by NOAA) and an average trend for the northern hemisphere. The anomaly values are plotted with respect to the average value of the respective base period of 1981–2010 (San Andrés Island), 1910–2000 (Caribbean Islands) and 1901–2000 (northern hemisphere).
