Miami’s overnight low on July 2 is expected near 80–82°F under typical early-July subtropical conditions, with high humidity and light winds limiting nocturnal cooling. Forecast models show modest spread driven by variable cloud cover and scattered thunderstorms, which reduce radiative heat loss and keep minima elevated compared with the long-term July average of roughly 78°F. Clear spells could allow brief drops toward the mid-70s, while persistent moisture and sea-breeze effects support readings in the low 80s. National Weather Service and ensemble guidance through the next 24–48 hours remain the key inputs, with any late adjustments to sky cover or precipitation timing likely to shift the precise minimum within the tightly bunched 76–83°F band that currently dominates market-implied odds.
