Forecast consensus from the National Weather Service and major models points to a high of 89–90°F in Miami on August 27, driven by typical late-summer conditions with southeast winds, high humidity, and a 50% chance of afternoon thunderstorms that cap daytime heating. This aligns closely with the 1991–2020 climatological average high of 90.5°F and recent model runs showing no strong ridging or cold front to push temperatures outside the 88–92°F window. Heat indices near 105°F reflect abundant moisture rather than extreme air temperatures, while scattered cloud cover and sea-breeze effects further moderate peaks. Updated NWS guidance and ensemble spreads released overnight reinforce trader focus on the 90–91°F bin as the most probable outcome.

To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
This market can not resolve until the first data point for the following date has been published on the resolution source.
The resolution source for this market measures temperatures to whole degrees Fahrenheit (eg, 21°F). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
