Understanding the Factors that Influence the Marine Weather Forecast

The marine weather forecast in Key Largo is influenced by a combination of factors, including wind direction and speed, wave height and period, tides, and atmospheric conditions. The Gulf Stream, a warm ocean current that originates in the Gulf of Mexico and flows northward along the eastern coast of the United States, also plays a significant role in shaping the marine weather in Key Largo. The Gulf Stream can contribute to increased wave heights and stronger currents, particularly during periods of strong winds or storms.
