How does the Ocean affect the weather along the coast?

The Japanese current carries cold water down from the north and causes the coastal climate to be cooler than the climate further inland since the prevailing west wind is cooled.

The Pacific ocean is warm so it would keep the coast warm/cool

Oceans will push cool air toward the land acting like an air conditioner

Yes! A high pressure system forms over cool water and a low pressure system forms over warm water. This creates surface winds. A cirrculation cell forms over the ocean from the currents under water....

Yes
