The NOAA Coral Reef Watch (CRW) daily global 5km Sea Surface Temperature (SST) Anomaly product displays the difference between today's SST and the long-term average. The scale ranges from -5 to +5 °C. Positive values mean the temperature measured is warmer than average; negative values mean cooler than average.

This product is updated each afternoon at about 13:30 U.S. Eastern Time.
