The best time to visit Clewiston is during the dry season, which runs from November until April. March, in particular, draws the most crowds due to Spring Break and the Clewiston Sugar Festival. Most wildlife sightings occur in the dry season between November and April, so opt for those months to increase the chances of spotting a rare Florida Panther. Temperatures rarely dip below 70°F, so campers can expect warm, humid weather year-round.
