Newfoundland is what I've been looking at for the last few hours. Studying up on its climate. It is considered the foggiest place on earth, I believe an average of 210 days a year have clouded conditions.

In response to the precipitation. I suspect that there will be continually varying density with cyclones, but it should be fairly heavy (I think).

I'm thinking about contrast thermal winds that collide near this area and cycling wind that blows it into the valley. Then the mountain wind keeps it bunched into the valley. There can be some volcanic activity along the shelf (which I THINK will promote a healthy aquatic environment), but I'm not sure the effects it would have overall.

With the chill. I think it needs to be at least 33 degrees, but not hot enough to reach a maximum of 75. I know that must be a tough if not impossible order. Any holes people would like to punch into the idea?
