Heck, we saw 12+ in July in Kings Bay by the little islands alone.
Yep that sounds about right, they leave in the winter as soon as the water/air temp starts to warm up because the grass they normally eat isn't very abundant in kings bay, so they want to leave there ASAP. They only go there in the first place for the warmer water but the kings bay area just can't sustain the huge amount of animals and the massive amount of found they eat (think 150 lbs of sea grass per animal PER DAY!) for very long and they leave as soon as possible because they are hungry. Some animals do return and stay there during the summer because the grass has grown back, so yes you probably will see more in the middle of summer than you will right now.
