During the summer months, snorkeling remains excellent on protected Caribbean-side reefs, although weather forecasts should always be checked during the Atlantic hurricane season.

Water temperatures generally range from 24°C to 29°C (75°F to 84°F) throughout the year, allowing comfortable diving with minimal thermal protection.

  • Wear a properly fitted mask and flotation device if needed.

  • Stay within your experience level.

  • Avoid touching coral, sea fans, or marine animals.

  • Keep a safe distance from turtles and rays.

  • Follow instructions from certified dive guides.
