It won't be quite as warm as Sanibel, but it will be pleasant. Maybe too cool to spend time in the water, but pretty for beach enjoyment. The crowds won't be too bad, but the pricing could be high because Spring is high season for Savannah Tourism.

I agree with the above. The water temperature is a little cold for the locals but depending on where you are from you may consider it nice.
The north end of Tybee sounds where you want to go. The beach is quiet with plenty of birds and dolphins. Going this weekend-can"t wait
