National Weather Service forecasts for San Francisco on June 12 point to a daytime high in the mid- to upper 70s, with model guidance showing modest warming from a strengthening offshore flow that can briefly suppress the typical marine layer. This keeps trader-implied odds clustered around the 74–79°F brackets, as small shifts in wind direction or cloud cover can alter peak readings at the official station by several degrees. June climatology features average highs near 69°F, but episodes of clearer skies and reduced onshore winds routinely produce 5–10°F anomalies. Final model runs and afternoon observations will determine resolution, with any late-day fog intrusion likely capping temperatures near the lower end of current expectations.
