Trader consensus clusters tightly around 80–83°F for Miami’s July 20 low, reflecting the subtropical marine influence that typically caps overnight cooling near 78–82°F in mid-July. High humidity and frequent cloud cover suppress radiative heat loss, while Atlantic sea-surface temperatures near 86°F maintain a warm boundary layer. Recent model runs show no strong cold front or unusual subsidence that would allow deeper drops, keeping sub-76°F outcomes below 35% implied probability. Forecasters from NOAA and local NWS offices highlight steady easterly flow and typical diurnal ranges of 8–12°F, with any variance hinging on tonight’s cloud timing and wind speed. Updated guidance tomorrow morning will refine the exact minimum before market resolution.

This market will resolve to the temperature range that contains the lowest temperature recorded at the Miami Intl Airport Station in degrees Fahrenheit on 20 Jul '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.
