Weekly Sea Surface Temperature Anomaly

This map displays weekly sea surface temperature anomalies for the globe.

Weekly sea surface temperature anomalies are calculated with respect to the 1991-2020 climatology. Yellow to red colors on the map indicate areas where sea surface temperature for the week shown is above the climatological value for that week of the year, and blue shades indicate where sea surface temperature is below normal. Shading starts at +/- 0.5°C. Anomalies are also contoured at an interval of 0.5°C.
