2025 Northern California Tide Log

Daily Tidelog Graphics are based on NOAA predictions for San Francisco, at the Golden Gate Bridge. Time and strength of maximum currents and times of slack water are shown daily at San Francisco Bay Entrance and Carquinez Strait. Included at the back of the Tidelog are tide tables for Arena Cove, Port Chicago, and Humboldt Bay and current tables for the Golden Gate Bridge, Benicia Bridge, San Mateo, Richmond, and Oakland. Also included are Tidal Current Charts which offer a comprehensive view of the tidal currents throughout San Francisco Bay.
