Current National Weather Service and model guidance for Los Angeles on August 20 point to a daytime high in the upper 70s to low 80s, driven by persistent marine-layer influence and moderate onshore flow that limits inland heating along the coast. Ensemble forecasts show limited spread around these values, with typical August climatology near 83 °F serving as a baseline but recent cooler-than-normal patterns and patchy fog reducing peak temperatures. Trader-implied odds clustering on 78–81 °F reflect this consensus from official point forecasts and rapid-update models, while lower probabilities for 82 °F or higher account for possible brief clearing that could allow modest warming before resolution at official Los Angeles observation sites.
