Explain how the oceans effects our temperature in Florida

Ocean tempature affects local atmospheric pressure, that affect wind patterns that direct the ocean currents, driving them in a different direction.

Florida, a state that is next to the ocean, therefore meaning that you get more rain and your state tends to be more cooler.

Also you have wind currents going in, from the sea and out. Also making you able to live in a moist condition making the humidity rise (or decrease) making you get hotter.
