**Persistent marine layer and onshore flow are capping the daily high at Los Angeles International Airport (KLAX) near 70–71°F today.** Mid-June climatology features a strong temperature inversion and sea breeze that advects cool, moist air from the Pacific, limiting daytime heating along the coast even under mostly sunny skies. Official National Weather Service guidance and model consensus have held the forecast in the upper 60s to low 70s, consistent with recent days when marine stratus and fog delayed clearing and kept highs 3–5°F below seasonal normals of ~75–79°F. Traders have priced 70–71°F at 86.5% implied probability because real-time observations and short-range models show little potential for significant warming before sunset. Higher bins (72°F+) remain low-probability tail risks only if the marine layer erodes unusually early or offshore winds develop—conditions not supported by current data. The narrow distribution around the 70–71°F bin reflects both the tight forecast envelope and the resolution criterion tied to the KLAX station reading.
