El Niño is strengthening and preparing for an extended presence. Climate models predict the phenomenon will persist through fall and winter, continuing into spring 2027. Columbia University’s climate scientist Azhar Ehsan recently presented data showing a near-certain probability of El Niño extending to spring. Ehsan stated, “I wrote near-certain but it’s 100%.” The National Oceanic and Atmospheric Administration’s (NOAA) Climate Prediction Center concurs with this forecast, indicating a 100% probability of El Niño remaining for six more months. The prediction reflects data for various three-month periods projected by NOAA.
This El Niño event is expected to be unusually robust, accelerating more rapidly than any previous El Niño on record. It is anticipated to reach “super” strength in fall or winter. This will significantly influence weather patterns in the coming months, according to Nexstar meteorologist Brian James. He noted its impact on hurricane season, increasing activity in the Pacific while calming the Atlantic.
The effects of El Niño will vary across the United States. Northern states are likely to experience drier and warmer conditions than usual, while southern states will see cooler and wetter weather. Despite these general trends, occasional cold air masses may still affect central U.S. regions, and snow is still possible in the northern Plains. Overall, however, the pattern will not favor heavy snowfall across the northern U.S.
The Climate Prediction Center projects El Niño’s strength will diminish from “very strong” to “strong” by early spring, eventually settling into the “moderate” category.
