Is this a proper habitat for a rabbit?

I asked this before but I have changed the situation, I would keep my rabbit in my room with a dog fence. Just like a bunny x pen except its about 3 feet tall maybe taller. I would put my bunny in a outside pen for a few hours, 2-4 @ around 3 o clock. I live in san diego so tempertures rise over 80 degrees but they have 1/4 of shade and I. Will put a frozen ice bag in there cage and lots of cool water, they will have litter boxs in each cage 2 food bowls one with hay the other with pellets and a water bottle hooking on the side of there cage. I will take them out everyday for about an hour or 2. Is this a good lifestyle for them
