Conditions

Average sea temperature through the year. Check the live readings before you go.

Average sea surface temperature by month: NOAA CRW “Honduras” station climatology (monthly means).

Buoy readings are measurements; forecasts are models. Use them for planning only, and assess conditions on site. Depth and visibility data aren't listed until we can cite a source.

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.
