Mount Washington’s summit, at 6,288 feet, experiences extreme winds due to orographic enhancement, exposure to the jet stream, and frequent rime icing that affects measurement. As of mid-October 2026, the highest recorded gust stands at 110 mph on October 5, accompanied by the season’s first measurable snow, subzero wind chills, and thick rime per Mount Washington Observatory reports. Subsequent northwest flow events produced gusts to 103 mph on October 10 and 90 mph on October 14, with National Weather Service point forecasts showing sustained winds near 70 mph and gusts to 90 mph through October 15 before moderating. Remaining October days carry potential for stronger systems, but climatological medians for monthly peak gusts hover near 100–110 mph; traders monitor updated NWS model runs and observatory daily summaries for any exceedance of the current high.
