Briefings
NASA satellites tracked a historic El Niño event in 2026, with NOAA estimating an 83% chance of the strongest El Niño since 1950. Key indicators included a Kelvin wave spotted in January 2026 near Micronesia, which triggered warming in the eastern Pacific by early April. Sea surface temperatures in the eastern Pacific rose approximately 3 degrees Fahrenheit above the long-term average, and sea levels in the eastern Pacific rose by 1 to 1.3 feet. The ocean color data from the PACE satellite showed a measurable decrease in blue hues due to reduced phytoplankton abundance, while sea level data from Sentinel-6 satellites tracked water height changes with 10-day intervals.
Key points
- A Kelvin wave spotted in January 2026 near Micronesia triggered the start of an El Niño event by early April 2026.
- Sea surface temperatures in the eastern Pacific rose approximately 3 degrees Fahrenheit above the long-term average during the 2026 event.
Context
This briefing covers NASA's tracking of a rare El Niño phenomenon in 2026, supported by NOAA's 83% probability estimate. The event is significant because it is rarer than a solar eclipse and more powerful than any single storm system, affecting global weather patterns and sea levels.
Limitations
Evidence is limited to satellite imagery and altimetry data from 2025 and 2026. Some observations, such as the exact timing of the Kelvin wave's impact on trade winds, are inferred from the progression of sea surface temperatures and sea level changes rather than direct measurements.
