Mount Washington’s summit at 6,288 feet experiences amplified winds from orographic lift and steep pressure gradients, with August typically producing lower averages than winter but occasional spikes from tropical cyclone remnants or strong fronts. Historical peaks include 147 mph in 2020, though median daily maxima hover near 49 mph. As of late August 2026, July’s fourth-windiest conditions on record featured a 100 mph gust, while current summit observations show sustained winds of 25–36 mph with forecasts calling for gusts to 50–55 mph amid an approaching system. The Mount Washington Observatory’s F6 daily summaries, released at month-end, will set the official highest gust; any intensification or new model runs in the final 48 hours could push readings above 90 mph and shift market-implied odds for thresholds at 95 mph and higher.

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 August, 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’s summit at 6,288 feet experiences amplified winds from orographic lift and steep pressure gradients, with August typically producing lower averages than winter but occasional spikes from tropical cyclone remnants or strong fronts.
