NASA's Sentinel-6 Michael Freilich satellite has detected elevated sea levels and a massive warm Kelvin wave across the equatorial Pacific [1, 2, 3].

These observations indicate the presence of a Super El Niño, a climate phenomenon that can disrupt global weather patterns. The shift in ocean heat content and water levels often leads to extreme weather events across different continents.

The satellite imagery reveals that the warm Kelvin wave spans hundreds of miles [3]. This wave consists of a band of warm water moving across the ocean, which contributes to the overall rise in sea levels in the equatorial region [1, 3].

Data confirmed the Kelvin wave was observed crossing the Pacific in 2026 [2]. The movement of this warm water is a primary driver of the Super El Niño's impact on the marine environment.

Oceanographers use the Sentinel-6 Michael Freilich satellite to monitor these changes in real time. By tracking the height of the ocean surface, NASA can identify the specific areas where water is piling up due to increased temperatures [1, 2].

Warm water shifts associated with this event increase the total ocean heat content. This process causes the sea level to rise locally in the eastern and central Pacific, creating the conditions necessary for a high-intensity El Niño event [1, 3].

The detection of a Super El Niño through high-precision satellite altimetry allows meteorologists to better predict global climate anomalies. Because Kelvin waves transport vast amounts of heat across the Pacific, their movement serves as a precursor to significant shifts in rainfall and temperature patterns worldwide, potentially increasing the risk of floods in some regions and droughts in others.
