National Weather Service forecasts and ensemble model guidance indicate a moderating marine layer influence and light onshore flow will likely cap the Los Angeles high near 77–80 °F on August 3, 2026, following several days of heat advisories. Recent observations show coastal temperatures running a few degrees below inland valleys, with persistent low clouds and fog expected to limit daytime heating. This pattern aligns with climatological norms for early August, when average highs hover around 84 °F but can vary several degrees based on boundary-layer moisture. The market’s heavy weighting toward the 78–79 °F bin reflects trader consensus on these near-term model runs and the low probability of significant warming before resolution.
