Strong El Nino Predicted for Winter 2026-27 - This Is What Skiers Need to Know

Sea surface temperatures in the central and eastern Pacific have risen since March, increasing the likelihood of El Niño. NOAA estimates an 82% chance of El Niño emerging by May-June-July and a 96% chance it persists through December 2026 to February 2027. By fall, there is about a two-in-three chance it reaches strong intensity, with Niño 3.4 anomalies above +1.5°C. The temperature outlook favors above-normal warmth across nearly all ski-relevant areas throughout winter. The strongest warm signal is in the northern tier, including the Pacific Northwest, northern Rockies, Great Lakes, and northern New England. No meaningful cold signal appears in the southern tier. Precipitation is expected to follow a classic El Niño pattern, with regional differences implied by the forecast maps.

"NOAA's Climate Prediction Center dropped its latest long-lead seasonal outlook on May 21, and yes, forecasting seven-plus months ahead is more art than science. Take it with the appropriate pinch of salt. That said, El Niño is knocking on the door, the signal is unusually strong for this time of year, and if you're the kind of person who likes to plan your season around something more than a hunch, the El Niño 2026-27 ski forecast is already shaping up to be one worth following."

"After a neutral winter, sea surface temperatures in the central and eastern Pacific have been climbing steadily since March. NOAA now puts the odds of El Niño emerging by May-June-July at 82%, rising to a 96% chance it persists through the core of winter (December 2026-February 2027). By fall, there's roughly a 2-in-3 chance it reaches "strong" intensity; Niño 3.4 anomalies above +1.5°C."

"The temperature story is unambiguous: above-normal warmth is favored virtually everywhere that matters to skiers, all winter long. The northern tier (Pacific Northwest, northern Rockies, Great Lakes, and northern New England) faces the strongest warm signal, with probabilities exceeding 50% above normal in December-January-February. The southern tier shows more uncertainty, but there's no meaningful cold signal anywhere."
