Strong winds at Mount Washington summit are driven by orographic lifting and exposure to passing low-pressure systems or tropical cyclone remnants, which can produce hurricane-force gusts even in September. The historical September maximum stands at 174 mph from Hurricane David remnants in 1979, per Mount Washington Observatory records, well above the typical monthly peak near 94 mph. As of early September 2026, National Weather Service observations at KMWN show sustained winds near 60 mph with gusts to 73 mph amid rain and fog, with forecasts indicating potential gusts to 90–100 mph later in the week from an intensifying system. Traders monitor real-time anemometer data and NHC/NOAA updates for any late-month tropical influences, as September climatology favors occasional spikes but rarely approaches all-time extremes without specific steering patterns or intensification.

This market will resolve based on the highest wind speed, in miles per hour, reported on the summit of Mt. Washington in New Hampshire in September, 2026.
The resolution source will be data published by the Mt. Washington Weather Observatory. F6 reports containing daily wind speed recordings can be found here: https://mountwashington.org/weather/mount-washington-weather-archives/monthly-f6/.
The resolution source for this market measures wind speeds to whole mile per hour (eg, 67mph). Thus, this is the level of precision that will be used when resolving the market.
Revisions to the wind speed recorded within this market's timeframe will be considered until the first datapoint for the following month has been published, after which any alterations will not be considered.Strong winds at Mount Washington summit are driven by orographic lifting and exposure to passing low-pressure systems or tropical cyclone remnants, which can produce hurricane-force gusts even in September.
