NASA Confirms El Niño Conditions Are Now Underway
NASA satellite observations have confirmed that El Niño conditions are now underway. According to data from the space agency, sea surface height measurements indicate the 2026 El Niño event continued to strengthen in early June.
El Niño is a natural climate pattern characterized by warmer-than-average sea surface temperatures in the central and eastern tropical Pacific Ocean. These conditions can significantly influence weather patterns worldwide, affecting rainfall distribution, storm activity, and temperature regimes across multiple continents.
The NASA Earth Observatory tracks El Niño development through satellite measurements of sea surface height, which serve as an indicator of ocean heat content. Elevated sea surface heights typically accompany El Niño events as warmer water expands.
