Current forecasts from the National Weather Service and models indicate a high near 80–89°F for Los Angeles on August 21, driven by persistent marine layer influence and onshore flow that moderates coastal temperatures despite broader regional warmth. This positions the 80–81°F bin as the leading outcome at 47% implied probability, followed closely by 78–79°F at 33.5%, reflecting typical late-August climatology where average highs hover around 84°F but LAX-area readings often run several degrees cooler due to sea breezes. Minor model variations in cloud cover and wind timing account for the spread into the low 80s, with negligible odds above 85°F given the absence of offshore flow or heat dome conditions in the latest guidance.
