Current National Weather Service and model guidance point to a high near 70 °F in downtown Los Angeles on May 17, driven by a persistent marine layer that has kept coastal temperatures below seasonal averages in recent days. This setup favors the 68-69 °F bin as the market leader, with the next-lower range reflecting lingering uncertainty in how quickly the layer mixes out. Typical May climatology shows an average high of 74 °F, but the current pattern of onshore flow and overnight low clouds has trimmed peak readings by 3–5 °F over the past week. Traders are watching the next NWS update and morning satellite imagery for signs of earlier clearing that could push readings into the low 70s.
