Upper ocean heat east of the Dateline in the equatorial East Pacific is steadily increasing. The warming is attributed to an eastward shifting Kelvin Wave which has increased intensity during January. The upper ocean heat warming is similar with 2023 ahead of an El Nino event that developed later that year. Global SSTA forecasts have adjusted to the evolving El Nino scenario for quarter 2 of 2026.
