Crystal River in Citrus County is quite busy during winter time due to the huge number of manatees in King’s Bay. It’s the largest gathering of manatees in North America.

The West Indian Manatee migrates to Crystal River and the surrounding springs roughly mid-November and stays around the springs until mid-March. Guided tours are offered from November to end of March. You experience most activity during the early morning. If you like to get interactions with manatees book the early morning tour in advance! The most popular and best swimming tours are offered by River Ventures USA: Crystal River Florida - 3 Hour Swim with Manatees (safe and reliable booking via GetYourGuide, with excellent service). Book in advance (see below)! Even if you don't plan to swim with manatees, visiting the area to spot these amazing creatures is amazing.

The manatees come here during winter time because they get stressed by the cold gulf if the temp goes below 68°F / 20°C. Although they look like to be prepared for cold temperatures. Their bodies have not much fat for insulation. The springs have a constant temp of 74°F / 23°C. The reason that they gather around the springs. During high tide, they move to the Three Sisters Springs, and at low tide, they gather outside in the channel at Idiot’s Delight I and II. Often hundreds of manatees can be seen at the springs at once.


Florida Manatee Calendar (Summer - Winter)

While manatees can be found in large numbers from mid-November until mid-March, exceptions are possible. In 2018 for example they already left the springs mid-February due to an unusual high day temperature. On the other hand, in one year they stayed until April, even early May. But still, you should stick to most likely months:

Mid-November | December | January | February | March

This is the time to spot Manatees and swim with them. The population in Crystal River goes up to 600-800 manatees. That's why so many visitors are coming in the winter months. Be prepared for competing with the best tour spots with hundreds of others. That's why it's critical to book in advance: Crystal River Tours - Florida (via GetYourGuide, safe booking and extremely reliable).

April | May | June | July | August | September | October

These are the unpleasant and unlikely months. From spring (April and May) throughout summer (June, July, August) until the fall (September, October), you won't see large numbers of Manates in Florida, as they migrated to the ocean. That's why the manatee population ranges between 60-90 only in the Crystal River area outside of the winter months. That also means, there are still some manatee residents, and there is a chance that you might spot one or two. It's still a nice overall experience as it's much quieter of course with very few other visitiors. 


Best Time of Day

It is almost impossible to avoid crowds while swimming with the manatees. Even in the early morning expect 30 to 40 people in the water. The Three Sisters Springs, however, are tranquil when they open the gate early in the morning and the manatees are most active during that time of day. That means, early morning bookings are necessary for the best experience, regardless of other visitors. Just want to spot the manatees without swimming? Also get there early in the morning, as this is the time when the manatees are active.


Weather

During the peak season of the manatees, it can be pretty chilly in the morning. On average it's roughly 50°F / 10°C cold in the early morning. We experienced 28°F / -2°C which happens rarely. It was pretty cold when we got out of the water. Day temps are usually between 58°F / 15°C and 70°F / 21°C. Precipitation occurs year-round with its peak in the summer months. It’s quite hot and muggy in the summer and temps are around 90°F / 32°C.


How Long to Stay

Regardless if you plan to swim with manatees or just want to spot them, we highly recommend staying here for a couple of days. Visit the Three Sisters Spring, have a look to one of the many other springs like the Rainbow Springs and enjoy the manatee encounter. Actually, we planned camping in the Rainbow Springs State Park. Due to the cold night temps of 32°F, we booked a room at the Hampton Inn Crystal River instead last minute. It was just a 5 minutes drive to our manatee tour the next morning. We loved the great breakfast each day. More alternatives can be found here: Hotels in Crystal River - via booking.com with price guarantee
