**Persistent warm overnight conditions during an early October heat wave positioned the 76-77°F bin as the clear leader in trader sentiment for Los Angeles's October 4 low temperature.** Official National Weather Service observations recorded a minimum of 77°F at downtown stations, with forecasts from multiple models converging on 77°F lows amid clear skies, light winds, and elevated daytime highs exceeding 100°F. These factors limited radiative cooling compared to the historical average low near 62°F. Market-implied odds reflect strong consensus around this outcome, with lower-probability bins for cooler readings (e.g., 70-71°F or below) indicating limited expectation of significant model shifts or localized cooling prior to resolution. Upcoming climatological summaries from agencies like NOAA will confirm final values for any edge cases in station-specific readings.
