Predicted for Tarlatt Slough, 4.3 km away (reliability: high — a close match — expect predictions within a few minutes of the published station table). Heights and times are that station's own published offsets applied to harmonic constituents from Toke Point, its reference station 40.1 km away.
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 Long Beach.
Fishare reads the tide, weather, light and moon for your spot and pings you when the next 3-hour peak window opens. The forecast, saved spots and catch log stay free, forever.
