Do El Niño conditions mean more snow for Colorado ski resorts? Here’s what the data shows.

As El Niño conditions strengthen, so do the hopes of abundant snowfall for ski resorts across Colorado. While the shift in sea surface temperatures could provide a precipitation boost for some resorts, historical records suggest that’s not always the case. According to the National Oceanic and Atmospheric Administration’s latest Oceanic Niño Index reading, El Niño conditions — characterized by above-average sea surface temperatures in the Pacific Ocean — continued to strengthen in September. Sea surface temperatures have exceeded 4 degrees celsius in portions of the eastern equatorial Pacific, with meteorologists predicting that a “very strong” or “super” El Niño is not far behind. An October outlook published by the Climate Prediction Center indicates El Niño conditions could continue to strengthen through the end of the year, maintaining a possible transition to a very strong or “super” El Niño by January-March 2027.
