In Key Largo, August is one of its slowest tourism months, and lodgings cost slightly lower. The seawater is at its warmest in August, and average sea temperatures at 86.7°F. This temperature is deemed unpleasant, and is not favorable for swimming and other related activities, as the cooling effect of the water is absent.

At nights, temperatures are warm, dropping down to 59°F and lesser than 40°F in January. This occurs because the Keys are generally situated in a subtropical region, close to the Gulf Stream and Gulf of Mexico.

The winter season (although not your typical winter) is the best time to visit.
