There are debates about boaters as to what is the best season to travel by boat from Florida to the Bahamas. The reality is that boating is pleasant and possible the whole year. Different periods present different pros and cons. If you are a seasoned boater you will probably know how to mitigate weather’s risks and stay out of trouble. The only area that can pose a problem is when boats leave the coast of Florida they may encounter the effect of “the Gulf Stream System” . The Inner edge of the system is around 10 miles offshore; it may result in increased current and more agitated seas.
From December to April the weather is cooler and dryer and overall more stable, however crossing the gulf stream at this period is not the calmer.
If you intend to dock at marinas or to find sheltered anchorage it is more expensive and more challenging. You will need to reserve your dock in advance and rates are at the highest.
From June to end of October it is the Hurricane season however, they rarely reach the Bahamas and the only good thing about “hurricanes” is that they are announced sometimes up to 10 days in advance so there is plenty of time to find a safe harbor in the Bahamas or in the US. Marinas are way less busy and much cheaper. Summers are less windy with a few short term daily showers.
