Official National Weather Service forecasts for San Francisco on June 9 project a daytime high near 69°F under mostly cloudy morning conditions transitioning to gradual clearing, driven by persistent onshore westerly flow and a moderating marine layer typical of early June along the central California coast. This climatological baseline, with historical averages around 67°F, supports the tight clustering of market-implied odds between 66-69°F as traders weigh model consensus on wind patterns and boundary-layer moisture against potential afternoon warming if skies clear more rapidly than expected. Minor uncertainties in local microclimates and exact timing of clearing introduce the narrow spread across adjacent bins.
