Geographic Factors

The water temp in destin florida benefits from several geographic advantages:

  • Protection from Atlantic Ocean currents
  • Shallow continental shelf extending far offshore
  • Warm gulf stream influences
  • Subtropical climate zone location

Factors Affecting Water Temperature

Weather Patterns
