Forty-one summers of heat

Each stripe is one year since 1985, colored by its peak heat stress across NOAA's “Leeward Caribbean Islands” region. These are NOAA Coral Reef Watch satellite figures for the whole region, not for this one site.

Conditions

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

Average sea surface temperature by month: NOAA CRW “Leeward Caribbean Islands” 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. 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.
