Record high ocean temperatures are back across the North Pacific when looking at March 2026 in the historical record for that month.

This graph shows the average for a band across the midlatitudes for every March from 1854-2026 using
NOAA ERSSTv5 data (https://psl.noaa.gov/data/gridded/data.noaa.ersst.v5.html).

@ZLabe what, would you say, are the implications on global air temperatures, for the coming year or so, of this spike in ocean temperatures?

@jcmortreux We are already seeing marine heatwaves across the Pacific, including a high-impact one off of Southern California and Mexico.
