Best time to Visit Key Largo

With the Key Largo water temperature ranging from 69 degrees in January up to 87 degrees in July and August, it is ideal for swimming throughout the year, and with a wide range of ocean-going activities on offer including scuba-diving, snorkeling, sports fishing and boating, there is plenty to do.
