Mount Washington Observatory instruments at 6,288 feet routinely record gusts driven by steep pressure gradients and orographic effects, though August averages are markedly lower than winter peaks due to weaker synoptic systems. Historical August maxima, such as the 147 mph gust tied to Tropical Storm Isaias, underscore how landfalling or nearby tropical cyclones can produce the month's strongest winds. With 2026 hurricane season forecasts indicating near-normal Atlantic activity and no major systems imminent as of late July, trader consensus reflects limited near-term catalysts for extreme readings. Upcoming National Hurricane Center updates and regional model runs through early August will refine steering patterns and intensity projections that directly inform resolution thresholds.

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.
