Question about climate on a hypothetical piece of land.?

Question

The hypothetical piece of land has mountains on the North and West sides. South and East are bordered by the ocean. What would the weather/climate conditions be like? The area I believe would be about half the size of the United States and naturally square.

Answer 1

Hard to determine based on what is given.  I would need to know the prevailing wind direction and general latitude, as they  would have effects on precipitation, rain shadow effects, temperatures, etc.

Answer 2

Hypothetically it would be catastrophic.
