Mount Washington Observatory data show July typically features the year's lowest average wind speeds around 25 mph, driven by a weaker jet stream and more stable summer patterns, though thunderstorms and cold fronts can still generate gusts exceeding 100 mph. The July record stands at 154 mph from 1996, far below the all-time 231 mph April peak, with 130+ mph gusts occurring in some but not all Julys. Continuous anemometer monitoring at the summit provides official resolution data, and traders should watch for any early-July convective outbreaks or frontal passages that could elevate extremes before the month ends.

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.
