The Atlantic Ocean off Florida is much warmer than the Pacific off CA, so the breezes off the Atlantic must be fairly warm. They may help a bit by moving the air around like a fan, but there is nothing like the CA coast breezes (more frigid in a NorCal than SoCal) that bring the fog in to cool things off.
The "pump" that brings in the coastal breezes and fog is the heating up of inland areas. As the inland areas heat up on summer days, the air rises, the pressure goes down, and this draws in the cold higher pressure ocean fog and winds during the afternoon.
The stratus/fog layer tends to be higher in SoCal because it is a bit warmer than in NorCal, so the ground visibility is better. In NorCal, the fog is colder, so it often comes in right at ground level and reduces visibility to "pea soup" conditions. The late spring/early-mid summer temps along the coast in NorCal are often around 55-65F, in SoCal 65-70F with frequent overcast and drizzle from the stratus clouds, especially from May-early July in SoCal, and May-early August in NorCal.
In late August into late September (sometimes into October), both SoCal and NorCal coastal temps warm up, and the foggy weather is less common. Santa Ana and Diablo Winds can also dry and warm things up in Autumn in both SoCal and NorCal, and cause wildfires to spread.
