The rule that runs the season
Manatees can't tolerate water below 68 degrees for long — so when the Gulf and the rivers turn cold, they head for reliable warm water: constant-temperature springs and power-plant outflows. That's the whole season in one fact, and the roundup film builds the statewide map from it: late November through March is the viewing window, and cold fronts are the best days.
Closest to Orlando: Blue Spring
Three films cover Blue Spring State Park in Orange City — the largest spring on the St. Johns River, a designated manatee refuge about an hour northeast of the theme parks, and the winter home of hundreds of West Indian manatees. Together they give the know-before-you-go (eight things), the boardwalk routine when the run is packed, and how to time your visit. This is the manatee trip an Orlando stay can actually do — boardwalk viewing, no boat required.
The other great refuges
- TECO Manatee Viewing Center (Apollo Beach) — boardwalks and observation platforms over the power plant's warm-water discharge; two films, one after a February cold front with the channel packed. Free, and far more than an observation deck
- Homosassa Springs Wildlife State Park — the Fishbowl underwater observatory at the spring head, the rescued-animal collection, and one of Florida's most reliable winter refuges, filmed on a chilly January morning
- The ranked map — a 10-best-places tour of the springs, refuges and outflows, the 2025 season edition
Want to be in the water with them instead? This site's Crystal River manatee swim page covers the one place it's legal — with its own seasonal rules. This page is the viewing season: where they gather, when, and how to watch without disturbing them.
