Persistent marine layer conditions driven by cool offshore Pacific waters and seasonal upwelling are anchoring San Francisco's daily high near 70–73°F on June 17. Strong northwest flow and a pronounced temperature inversion limit vertical mixing, suppressing afternoon warming even as interior valleys climb higher. Recent observations show sea-surface temperatures running several degrees below the June climatological average, reinforcing the stable layer and coastal stratus that typically caps readings at or below the mid-70s. National Weather Service model consensus and historical June analogs at KSFO align with this range, leaving only modest probability for excursions above 74°F if the marine layer erodes earlier than expected.
