Annual Water Temperature Trend

Little Torch Key sits in the lower Florida Keys and enjoys subtropical, relatively warm waters year-round thanks to the nearby Gulf Stream influence. Seasonal surface temperatures typically run from about 22–24 °C in the coolest winter months (December–February), rise through spring to roughly 24–27 °C (March–May), peak in summer near 28–31 °C (June–August), and ease into the mid to high 20s °C in autumn (September–November). These figures can vary with short-term weather patterns, cold fronts or unusual heat, but overall the area maintains milder sea temperatures than much of the continental U.S., so the water remains inviting for much of the year.
