Recent National Weather Service forecasts for Miami indicate an overnight low in the mid- to upper 70s on October 5, consistent with typical early-October patterns where the climatological average low reaches about 76°F. Persistent easterly flow and high humidity from the Atlantic, combined with a modest chance of evening showers, are limiting radiational cooling and keeping temperatures elevated relative to historical minima. No strong cold fronts or dry-air intrusions are expected in the short term to drive readings into the low 70s or below. Model consensus from recent runs supports this range, with limited variability in steering patterns or cloud cover that could alter the minimum. Traders appear to assign elevated implied probability to cooler outcomes based on seasonal variability, though updated NHC and local guidance ahead of the date will provide the next key data points for resolution.
