Pacific Climate Update: Recent Trends and Outlook
SST anomalies near Ecuador and Peru have slightly weakened, while above-average SSTs strengthened in the east-central Pacific. A moderate strength El Niño is favored, with westerly wind anomalies strengthening over the equatorial Pacific. Upper ocean surface and heat content evolution indicate ongoing climate dynamics.
