Weather forecasts for June 29 point to a San Francisco high near 70°F, reflecting the dominant influence of the marine layer over the cold California Current and persistent onshore westerly flow that limits inland heat advection. Recent National Weather Service discussions note a moderately deep marine layer with variable stratus clearance, keeping coastal maxima well below seasonal interior peaks while allowing brief afternoon warming if winds relax or the inversion strengthens. This setup creates tight clustering around 68–73°F outcomes, as small forecast shifts in layer depth, wind speed, or solar insolation can easily move the daily peak by a degree or two. Historical June averages near 67°F provide baseline context, with current model consensus favoring slight above-normal readings amid ongoing coastal upwelling.
