Accurate tide predictions for 20,112+ stations across 204+ countries
Powered by harmonic analysis — the same method used by national hydrographic offices worldwide
Accurate high and low tide predictions with smooth interactive charts. 7-day, 15-day, and monthly calendar views.
Find the best fishing times with solunar ratings based on moon phase, lunar distance, and spring/neap cycles.
Sunrise, sunset, moon phases, illumination, and tidal strength. All the conditions you need at a glance.
Plan ahead with full monthly calendars showing every high and low tide, moon phases, and daily conditions.
Whether you're casting a line, catching waves, or exploring tide pools — check the tides first.
Check tide conditions before heading out. Incoming tides and mid-tide windows deliver the best waves at most breaks.
Solunar ratings, spring/neap indicators, and tide changes help you find the most productive fishing windows.
Know when the beach will be widest, when tide pools are exposed, and when it's safest to swim.
Plan coastal shoots around low tides for dramatic rock formations, or high tides for reflections and wave action.
Time your launch and landing with the tide. Avoid getting stranded on mud flats or fighting strong tidal currents.
Visiting tidal landmarks? Check when causeways are passable, when harbours are accessible, and when to explore.
