Trader consensus on Miami’s August 2 overnight low centers on 80–81 °F (41 % implied probability) because current National Weather Service and ensemble guidance from NOAA project a typical midsummer nocturnal minimum near 79–81 °F under persistent tropical moisture and light winds. High dew points (near 75 °F) limit radiational cooling, while the urban heat-island effect and warm Atlantic/Gulf waters keep surface temperatures elevated; climatological normals for early August place the average low at 78–79 °F, with recent model runs showing only modest day-to-day variability. The secondary 82–83 °F bin (27 %) captures any slight warming from increased cloud cover or delayed sea-breeze onset, while the 78–79 °F tier (24.5 %) reflects the lower tail of forecast spreads if clearer skies develop overnight. No significant frontal passages or tropical systems are expected to alter the pattern before the 24-hour verification window closes, keeping the distribution tightly clustered around the market’s top outcomes.
