Tides for shore divers
Tides significantly impact shore diving. Knowing when to enter and exit is key to ensuring you don’t end up in dangerous surf or far from your gear.
Tides change the landscape
Always check the tide chart for your specific entry point. A site that is easy to enter at high tide may be impossible at low tide.
Why tides matter
Tides dictate water depth, current strength, and entry/exit safety at shore sites. A shallow area might become inaccessible during low tide due to rocks or surf.
Researching your site’s specific tidal behaviors is a fundamental part of pre-dive planning.
Timing your entry
Many shore divers prefer diving near slack water, when tidal movement is minimal. This reduces current strength and makes entries and exits easier.
Consult local dive guides or talk to fellow divers to understand how the tide affects your chosen location.
Planning your exit
Always plan your dive duration with the tide in mind. An exit point that is clear now might be difficult or dangerous an hour later.
Have an alternative exit point ready in case the tide changes unexpectedly.
