The climate on Harbor Island is delightful, with a semi-tropical warmth and enough of a seasonal change to keep it interesting. Springtime blooms early and fall arrives late. There are even days in the middle of December that edge up to low 70s and high 80s. Overall, the year-round average of midday and evening temperatures are approximately 75 and 55 degrees, respectively.
Though all sports are enjoyed year round on the island, even water sports enthusiasts have an advantage on Harbor, since waters are warmed from the Gulf Stream, heating the sea to a year-round average of 69 degrees. And in the spring the ocean heats up quickly, beckoning even the most particular swimmers and sun-worshippers in for a dip.
