Mt. Washington’s extreme exposure at 6,288 feet, combined with frequent passage of mid-latitude cyclones and strong pressure gradients, routinely produces August gusts exceeding 90 mph despite lower seasonal averages than winter. Observatory data through mid-August 2026 show only modest sustained winds (13–50 mph) and peak gusts near 55–67 mph, well below the 147 mph historical August maximum recorded in 2020. Traders assign near-certain implied probabilities (>98%) to outcomes of ≥90 mph or higher because remaining days allow time for typical frontal systems or convective events to deliver qualifying gusts before month-end resolution. Key upcoming drivers include updated NOAA and NWS higher-summits forecasts plus real-time anemometer readings from the Mount Washington Observatory, which define the official peak gust using standardized instrumentation.

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.
