Marine layer advection from the Pacific continues to moderate San Francisco temperatures, with National Weather Service guidance indicating a high near 66°F for July 7 amid gradual afternoon clearing. This keeps trader consensus tightly clustered on the 64–67°F bins, reflecting model agreement on onshore flow and stratus persistence that limits daytime heating. Key variables differentiating outcomes include marine layer depth and wind speeds, which control how much solar radiation reaches the surface before any late-day clearing; stronger or thicker layers favor the lower 64–65°F range, while quicker erosion could push readings into the upper 60s. Typical July climatology of 67°F highs provides context, yet the current pattern aligns with cooler coastal conditions observed in recent days. Updated model runs tomorrow morning will refine these thresholds ahead of market resolution.
