Current National Weather Service and ensemble model guidance for San Francisco on June 30 points to a high near 66–69°F, aligning with the market’s tight clustering on those bins. Persistent onshore flow and a shallow marine layer off the Pacific are expected to limit daytime warming, consistent with climatological norms where June highs average 67°F at downtown and airport stations. Recent model runs show no strong offshore wind shift or upper-level ridge that would allow temperatures to reach the low 70s, while fog clearance timing and boundary-layer mixing remain the key variables that could nudge readings slightly higher or keep them capped near 66°F.
