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.**Current conditions at the Mt. Washington Observatory summit show light winds, with recent observations around 4–6 kt sustained and minimal gusts amid fog and low-level clouds, consistent with typical late-August patterns.** Historical August peak gusts average near 86 mph but spike primarily from tropical cyclone remnants, as seen in the 147 mph record from Tropical Storm Isaias in 2020; no such systems are forecast to affect the region before month-end. July 2026 recorded a 100 mph gust and ranked as the fourth-windiest July on record, yet August data through late in the month indicate subdued activity without comparable events. Official daily summaries from the observatory will determine the final maximum, with only a few days remaining for any late-month shift.
