FAQ
Questions Tide Calculator owners ask.
- 01
How accurate are these tide predictions?
Predictions use a sinusoidal approximation with a 12h 25m period and adjust for spring/neap cycles based on lunar phases.
- 02
What tidal patterns are supported?
The server supports semidiurnal, diurnal, and mixed tidal patterns.
- 03
Can I find out if the current is flood or ebb?
Yes, by using predict_tidal_currents, you can determine if the water is moving toward the shore (flood) or away from it (ebb).
