Recent National Weather Service forecasts project a Miami high near 90°F on August 28 amid partly sunny skies and a 40-50% chance of afternoon showers or thunderstorms. This aligns with late-summer climatology, where sea-breeze convergence and daytime instability often trigger convection that limits peak readings through cloud cover and evaporative cooling. The tight market split between 90-91°F and 92-93°F captures genuine forecast uncertainty around storm timing and coverage, as earlier or more widespread activity could cap the maximum while delayed development might allow brief climbs into the low 90s. High humidity will elevate heat indices above 100°F regardless, but official observations will resolve the exact daily maximum.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Miami Intl Airport Station in degrees Fahrenheit on 28 Aug '26.
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.Recent National Weather Service forecasts project a Miami high near 90°F on August 28 amid partly sunny skies and a 40-50% chance of afternoon showers or thunderstorms.
