Bro??
You have a point about planting new plants/grass in the summer. I've heard about that too. But the summers here in Oregon usually don't get too hot. Just a few days here and there. Besides, if I can get something in there in the next week or so we still have about a month and a half of rainy/cool weather left. But, I may just wait until fall to plant stuff since I'm thinking of doing some patio work first anyway.
