San Francisco County Weather & Marine Report

Issued: June 3, 2026 � 8:00 AM PDT

San Francisco County will see morning clouds and patchy fog giving way to increasing sunshine through the afternoon. High temperatures are expected to reach the upper 60s to low 70s near downtown, with cooler conditions along the immediate coast. Gusty northwest winds will strengthen through the day, especially near the shoreline and exposed headlands, creating breezy conditions for beachgoers and mariners.

Marine conditions remain active offshore with a mixed swell pattern. NOAA marine forecasts indicate northwest winds increasing to 20 to 30 knots with higher gusts during the afternoon. Combined seas are generally running 5 to 6 feet offshore, producing average wave heights around 5 feet. Small craft should exercise caution, and gale-force gusts are possible over outer coastal waters.

Nearby offshore buoy observations west of San Francisco indicate dominant swell energy from the west-northwest, with swell direction around 285 degrees. Dominant swell periods are averaging 8 to 9 seconds, while longer-period background energy near 14 to 17 seconds continues from the southwest. Significant wave heights are generally between 4 and 5 feet offshore.

Tides today feature a morning low tide followed by a midday to afternoon high tide, then another lower evening tide cycle. Water levels are moderate and typical for early June, with no significant tidal anomalies expected.
