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.Early September 2026 has featured moderate summit conditions at Mount Washington, with NWS observations and forecasts showing sustained winds mostly 20-40 mph and gusts rarely exceeding 45 mph amid fog and light variable flow. Historical September extremes, such as the 174 mph peak gust from Hurricane David's remnants in 1979, often stem from tropical cyclone interactions that amplify orographic lift and downslope acceleration on the exposed 6,288-foot peak. Trader sentiment reflects the quiet start, tempered by uncertainty in Atlantic tropical development and steering patterns tracked by the National Hurricane Center. Key upcoming factors include updated NOAA model runs for any late-month systems and real-time data releases from the Mount Washington Observatory, which could shift odds if stronger gusts materialize before month-end.
