Plan & prepare

  1. Read the official marine forecast the night before.Offshore, wind and sea state decide the day.
  2. Check the cited local rules above and pay any park fee before you dive.[Placeholder: verified operator list to come]
  3. Study this month's species above.You'll recognise more when you know the names.
  4. Hands off, fins up, buoyancy dialled. Log what you see.Your sightings can become tomorrow's open data.
