It really just varies. One day it can be cool another it may be warm. So basically the climate of the Marine Biome is room temperature most days when you average it. Hope this answer helped :)!
It doesn't really have a climate the water temps change every day depending on the temperature an land.
Climate does not have much affect on the marine biome, but the marine biome largely affects our terrestrial climate! The ocean is a large influence on whether the weather may be sunny or cloudy, especially in Santa Barbara because the ocean is right out the back door.
