Tide
Definition
Tides are the regular rise and fall of sea levels caused by the gravitational pull of the moon and sun.
More on Tide
Tidal movements impact dive planning, especially for shore and reef dives. High tides may offer easier entries, while low tides can expose hazards or limit access. Tidal currents—especially during mid-tide—can also affect visibility, navigation, and safety. Tides are predictable and vary by location. Divers use tide tables or apps to choose ideal dive times and avoid strong currents or poor visibility. Some dive sites are only accessible or safe at certain tidal stages.
Frequently Asked Questions
Tides can impact visibility, water depth, and current strength—especially near shores and inlets.
High tide generally offers better visibility and safer entries, but check site-specific guidance.
Use tide tables, marine forecasts, or mobile apps that show local tidal changes and timing.
It’s water movement caused by rising or falling tides. Mid-tide often has the strongest currents.
Yes. Many species feed, migrate, or hide based on tide cycles. Timing dives with tides can improve sightings.
