Predicted from SAN DIEGO (Broadway), 33 km away (reliability: medium — a moderate distance — local times may differ by 10–30 minutes from the open coast).
These are astronomical tide predictions — the rise and fall driven by the moon and sun, computed by harmonic analysis. They do not include weather effects: a strong onshore wind, low barometric pressure or a storm surge can push the real water level above the predicted high, and offshore winds or high pressure can hold it below the predicted low. For navigation or any safety-critical decision, always check the official tide tables and a live water-level gauge for Oceanside.
