Forecast models from the National Weather Service and international sources indicate mostly clear skies, light westerly winds, and minimal marine layer influence for San Francisco on October 6, supporting overnight lows in the upper 50s to low 60s Fahrenheit. This aligns with trader emphasis on the 56–71°F bins, as coastal radiative cooling under high pressure typically yields minima near or slightly above the early-October climatological average of 55°F. The elevated 48.5% implied probability on 72°F or higher reflects uncertainty in exact minimum timing and potential for warmer advection if winds remain light or subsidence strengthens. With resolution hinging on official station readings the following morning, any late-model shift in cloud cover or wind could quickly adjust these market-implied odds.
