Very often in the Bahamian islands, the weather is like what South Florida is experiencing. Google islands to find out their rainy seasons, which might sway you, as to booking your cruise.
Wind, that's at Mother Nature's whim. In November 2010, we couldn"t leave the pier in Cozumel, due to the high winds, so we had to overnight.
But Aruba has the trade winds that bend the Divi Divi trees,a constant there.
So, pack, a travel umbrella case of rain, and hope the wind won't blow you away.
