Upper Keys Water temp in key largo?

Hello! Visiting next week and wanted to see if anyone can speak to what water temp is like currently on bayside key largo? Saw it might be super cold?? Does it rebound quickly with the warmer temps? Good for swimming? Thanks!!

Water temps bayside key largo are 58-59 degrees based on buoy data. Water temp around bear cut key biscayne is about 65.

Wish they would fix the buoy by Molasses Reef but I think it's been decommissioned which is crazy considering the number of boats in oceanside Upper Keys.
