Official National Weather Service observations for Los Angeles on September 12, 2026, recorded a daily maximum of 80–81°F at the primary resolution station, aligning with the strong marine layer influence typical for mid-September along the coast. This kept afternoon highs near the 1991–2020 climatological average of 76–77°F despite seasonal warming trends, as onshore flow and low clouds suppressed further intensification. Trader consensus at near-certain implied probability for the 80–81°F band reflects confirmation from verified hourly data and absence of heat-wave conditions. An upward revision in the final climate summary or use of an alternate downtown station could theoretically shift the outcome into the 82–83°F range, though such adjustments are rare after preliminary reports.
