Mount Washington Observatory data show September gusts are frequently driven by tropical cyclone remnants or intensifying nor'easters, which exploit the peak's extreme exposure and orographic lifting to produce the month's highest readings. The all-time September record stands at 174 mph from Hurricane David's remnants in 1979, with typical daily peaks ranging 70-100 mph under strong pressure gradients. As of early September 2026, current summit conditions feature moderate northwest winds with gusts to 50-70 mph amid mostly benign flow, but forecasters from the National Weather Service and observatory models track any Atlantic systems that could intensify late-month gradients. Continuous anemometer measurements distinguish sustained speeds from instantaneous gusts, with resolution hinging on official observatory logs through month's end.

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.Mount Washington Observatory data show September gusts are frequently driven by tropical cyclone remnants or intensifying nor'easters, which exploit the peak's extreme exposure and orographic lifting to produce the month's highest readings.
