El Niño to Shape Massachusetts' Warmer, Wetter Winter in 2026-27
US · Published Sep 10, 2026
The National Oceanic and Atmospheric Administration (NOAA) has forecasted that the 2026-27 winter in Massachusetts will be significantly influenced by a strengthening El Niño pattern.
This climate phenomenon, characterized by warmer-than-average sea surface temperatures in the tropical Pacific Ocean, is expected to bring above-normal temperatures and precipitation to the region.

Impact & Risks

Massachusetts residents can expect a warmer and wetter winter, which may disrupt typical seasonal activities and impact infrastructure. Above-normal precipitation could lead to localized flooding, while warmer temperatures might affect snow-dependent industries like skiing. The strengthening El Niño, with a 90% chance of becoming very strong by late 2026, could also contribute to broader weather anomalies across New England. These changes may challenge public safety and preparedness efforts, particularly in areas prone to winter storms or flooding.
