Recent observations from Miami International Airport and surrounding stations, combined with National Weather Service model consensus, indicate peak temperatures stabilized in the upper 90s on August 18 amid clear skies, light southeast winds, and elevated dew points that limited nocturnal cooling. These conditions aligned closely with climatological norms for late summer in South Florida, where daytime heating under high pressure typically produces highs near 90–95°F without significant moisture influx or frontal passages to moderate extremes. Trader consensus at 100% implied probability for 98–99°F reflects skin-in-the-game assessment of preliminary data and historical analogs from similar high-pressure setups. Resolution could shift only if final NWS climatological reports revise the official maximum downward due to station-specific instrumentation differences or timing adjustments.

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 18 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.
