regional SST time series

These plots show area-averaged sea surface temperature (SST) from the daily NOAA optimum interpolated SST (OISST) dataset. Black line depicts the 1991-2020 long-term average. Thin gray lines correspond with individual years from 1982 through 2022. 2023 is plotted in red. 2024 (so far) is plotted in blue.

Dashed box on inset map denotes region for area averaging. Anomalies are computed relative to the daily 1991-2020 mean. Click any image to reach the full-sized file. Updated around 1400-1430 UTC for the previous day assuming no delays in SST data. (Note: not updated for February 29 during leap years.)

Status: most recent available file from NCEI is for 22 Jul 2024.

regional SST anomaly time series

These plots show SST anomalies relative to the black line in the regional SST anomaly charts above. Thin gray lines correspond with individual years from 1982 through 2022. 2023 is plotted in red. 2024 (so far) is plotted in blue.

Dashed box on inset map denotes region for area averaging. Anomalies are computed relative to the daily 1991-2020 mean. Click any image to reach the full-sized file. Updated around 1400-1430 UTC for the previous day assuming no delays in SST data. (Note: not updated for February 29 during leap years.)

 

 



 

 



current SST vs. 1991-2020 climatological peak



The above map shows locations that, as of the given date, exceed their annual peak value using a 1991-2020 average. If a location is at or above that value, the color indicates how far above that value they are. Dashed boxes indicate regions to assess percent coverage of at-or-above peak values: MDR in blue, Gulf of Mexico in green, area where most ENP TCs form in purple. Those percentages are listed in the upper left part of the plot.

For additional context, the latest maps of SST and SST anomalies are given below:
