Official National Weather Service observations at the primary Los Angeles station confirmed a daily maximum of 70–71°F on June 4, 2026, anchoring the market’s near-certain positioning on that bracket. Persistent marine-layer stratus and onshore flow suppressed afternoon heating, consistent with early-June climatological norms around 71°F at coastal sites and preventing any push into higher ranges. No offshore wind events or clear-sky intensification materialized in the preceding 48 hours to alter this outcome. Realistic challenges would require revised station data or an unexpected late-day clearing that elevated readings beyond the measured peak, though current verification leaves little room for such shifts.
