When the manatees show up
Florida manatees migrate when the Gulf drops below about 68°F. The springs in Kings Bay hold a steady 72°F year-round, which is why they cluster here. Most years you will see early arrivals in mid-November and a peak count between Christmas and Valentine's Day.
November 15 – December 15 · Early season. Smaller crowds, fewer manatees but they are around every morning.
December 16 – February 14 · Peak season. Book tours and dates early. Cold mornings produce the biggest gatherings.
February 15 – March 31 · Late season. Warming days mean fewer manatees but easier tour bookings and calmer water.
April – November 14 · Off-season. A handful of resident manatees, but the legal swim-with program is suspended in summer.
