This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section. This market will resolve to the temperature range that contains the highest temperature recorded at the Miami Intl Airport Station in degrees Fahrenheit on 19 Aug '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Miami Intl Airport Station, available here: https://www.wunderground.com/history/daily/us/fl/miami/KMIA. To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C. 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 and AccuWeather model runs position Miami for a peak temperature of 96–97°F on August 19, driven by a strong subtropical ridge maintaining clear skies, light southerly flow, and minimal afternoon convection to limit cooling. This aligns with the market’s 52.5% implied probability for that bin and follows several consecutive days of 93–96°F readings that have already broken daily records. Typical August climatology centers near 89°F, yet persistent high pressure and elevated dew points have sustained above-normal heat. Updated short-range guidance and any late-day sea-breeze or thunderstorm development remain the key variables that could shift odds toward the 94–95°F range before the daily maximum is recorded.
