New · coastal sightings

See what’s out there before you get in.

The drfty community maps the marine life moving along the coast — orca, dolphins, seals, penguins, whales and stingrays, with a heads-up when jellyfish are about. Free to look, no account needed.

  • Free to browse the map. Sign in only to add your own sighting.
  • “Still here” or “gone” votes keep it honest, so the map shows what’s actually about.
  • Rewind the coast a day, a week or a month.

Sharks stay official-feed only, never crowd-reported. drfty won’t turn a shark scare into a notification.

Not just swimmers

For anyone making a call at the coast.

Useful for dog walkers, surfers, fishers, boaties, nature lovers, swimmers, paddlers and anyone wondering whether it's a yeah or a nah.
