Forecast models from the National Weather Service and other sources indicate a highest temperature near 89–90°F for Miami on August 27, driven by typical late-summer subtropical conditions with southeast winds, high humidity, and afternoon convective activity. Scattered showers and thunderstorms, expected mainly before late afternoon with 40–50% probability, can limit peak heating through cloud cover and evaporative cooling while sea-breeze convergence sustains instability. This consensus positions the 90–91°F bin as the market leader at 52%, with 88–89°F and 92–93°F as secondary outcomes reflecting minor variations in storm timing or intensity. Recent observations on August 26 showed similar patterns with highs in the upper 80s to low 90s amid comparable moisture and wind regimes, underscoring limited deviation from climatological norms absent major synoptic changes.

The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=kmia
This market will resolve off of the Hourly Data provided using the "Show Hourly Data" button.
If NOAA data is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
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.
