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
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.
Preview the tide schedule
Beyond right now, preview the upcoming high and low tide schedule. See how the tide moves and decide when to go before you leave.
Live 3s Three-second live wave logs
No photo uploads — just a three-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.
Good waves
Master
Wave ratings · beach masters
