Why wave-log

You drove an hour — and the tide was out

Some beaches are great at high tide and risky at low. Where travel apps give you a flat star rating, wave-log answers with activity × tide stage × time.

The time comes first

Surf Snorkel Swim Rest

Activity × tide suitability

Surfing, snorkeling, swimming, beach rest. Pick an activity and the map keeps only the beaches that suit it right now. Suitability is computed from the activity and the tide stage.

To high tide 1h 48m

Tide clock

See the time left to the next high or low at a glance, with the ebb/flow and spring/neap stage. “High tide at 14:32” — the time comes first.

Plan on a timeline

Instead of now, pick Saturday 2 PM this weekend and preview the suitability and tide stage for that moment. Decide before you leave.

Five-second live wave logs

No photo uploads — just a five-second video shot on site. The tide at posting time is stamped in. You can’t edit it, so it’s exactly what you just saw.
