Persistent heat across South Florida, including record or near-record high minimums recently observed in Miami, anchors trader consensus around 78–81°F as the likely lowest temperature on August 22. Warm Atlantic and Gulf waters, combined with high humidity and limited nocturnal cooling under mostly cloudy skies with scattered storms, sustain elevated overnight readings several degrees above the long-term August average of roughly 76°F. NOAA and NWS guidance highlight continued above-normal conditions without significant frontal passages or tropical influences expected to arrive in the next 24–48 hours. Model consensus supports modest variability in the upper 70s to low 80s, with the heaviest market weighting on the 80–81°F bin reflecting this baseline persistence amid inherent forecast uncertainty in boundary-layer moisture and local wind patterns.
