Official meteorological observations from Los Angeles stations, including those aligned with National Weather Service and NOAA reporting, recorded a daily maximum of 74-75°F on June 11, locking in trader consensus at near-certainty. June coastal conditions typically feature marine-layer moderation and onshore flow that suppress extremes, aligning with this measured outcome and historical baselines for early summer. Model runs and real-time sensor data showed no significant heat advection or clear-sky warming to push readings higher. A realistic challenge would require a post-event data revision from primary agencies or a redefined measurement protocol, both low-probability events given the consistency of surface observations.
