I think the water is getting cool enough now. They usually start to arrive about now!
We were there just before the end of 2018 and there were a lot throughout.
We were there Thursday. Saw one, but not a lot. The gulf water needs to drop to about 68 before they move into the warmer discharge water. It was still near 70 on Thursday.
We visited the park shortly before the turn of the year and there were many manatees there and have often been seen.
