Plan & prepare

  1. Read the official marine forecast the night before.Offshore, wind and sea state decide the day.
  2. Confirm access, hours and any fees with the site.[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.
