Mount Washington Observatory data show persistent moderate winds through late August 2026, with recent 24-hour gusts mostly 25–45 mph and a 32 mph reading on August 23 amid fog and light drizzle. These conditions, absent any approaching tropical systems or strong fronts per National Weather Service guidance, represent the main driver keeping market-implied odds heavily favoring outcomes below extreme historical thresholds. August climatology features mean speeds near 24.5 mph and median peak gusts of 42–50 mph, with rare spikes above 80–100 mph usually tied to remnants like Tropical Storm Isaias, which produced the 147 mph record in 2020. With only days left before month-end and stable southwest flow expected, final official summit observations from the observatory will resolve the maximum gust.

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 Observatory data show persistent moderate winds through late August 2026, with recent 24-hour gusts mostly 25–45 mph and a 32 mph reading on August 23 amid fog and light drizzle.
