Mount Washington’s summit, monitored continuously by the Mount Washington Observatory, experiences peak wind gusts in August that are typically far below winter extremes due to weaker temperature gradients and fewer intense extratropical cyclones. As of mid-August 2026, official observations show sustained winds of 40–48 mph with gusts reaching 64 mph, consistent with normal summer variability driven by passing cold fronts rather than major storms. The market hinges on whether any remaining August low-pressure systems produce higher gusts before month-end, with resolution based on the observatory’s calibrated anemometer data. Traders watch National Weather Service model runs and observatory daily summaries for signals of stronger nor’easter development or jet-stream positioning that could briefly elevate speeds. Historical August maxima rarely exceed 100 mph, underscoring the role of climatological seasonal decline in trader assessments.

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, monitored continuously by the Mount Washington Observatory, experiences peak wind gusts in August that are typically far below winter extremes due to weaker temperature gradients and fewer intense extratropical cyclones.
