This map displays the difference in sea surface temperature anomaly from the previous month.
Monthly changes in sea surface temperature anomalies are shown in units of °C. Yellow to red colors on the map indicate an increase in the monthly sea surface temperature anomaly from the previous month, and shades of blue indicate a decrease in the anomaly from the previous month. Contours are drawn at an interval of 0.5°C, and shading starts at +/- 0.5°C. Monthly sea surface temperature anomalies are calculated with respect to the 1991-2020 climatology. The time label displays the middle dates of the two months over which the difference is calculated; the difference is calculated as the temperature anomaly in the later month minus the temperature anomaly in the previous month.
