Predicted for BOSTON, 1 km away (reliability: high — a close match — expect predictions within a few minutes of the published station table).
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 Boston.
Tides are only half the picture — wind, swell and the bite window matter too.
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.
