I want to do night ocean photography. what weather conditions do i need for the longest view from shore?

I would like to go to a nice dark area for night photography in between san deigo and los angeles. But sometimes when i go out at night a mist over the ocean stops me from getting a good shot. I have over $4000 of new canon equipment including a tripod, external timers, bubble levelers and canon L lenses. i just need help in finding out what weather conditions i need to get the longest shot over the horizon, so i can see the stars all the way down.
