Recent National Weather Service and model guidance point to typical mid-August subtropical conditions limiting overnight radiational cooling in Miami, with dew points near 75°F and light winds sustaining minimum temperatures in the upper 70s to low 80s on August 19. Persistent warmth from a broad high-pressure pattern and high humidity have kept recent overnight lows at or above 80°F, consistent with climatological averages of 78–80°F and rare excursions below 74°F. Trader consensus favoring the 78–81°F bins reflects this stable regime, though any increase in cloud cover or convective activity could modestly enhance cooling and shift probabilities toward the lower end of the distribution.

This market will resolve based on the lowest 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 lowest 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 lowest 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.
