When is the Best Time to See Bioluminescence in Florida
Check the information below for the best times and dates to see bioluminescence. Most people try to come in the weekend before or after the new moon - we call these the "Dark Skies" nights. Keep in mind that we do amazing bioluminescence tours every night of the year, and the moon rarely prevents us from seeing glowing plankton or jellies.
