Our deck is such that an awning does no good. In the late afternoon, the deck, which is faces northwest, gets the sun below any awning. So I put a cantilever 'brella there, in that corner that is about 10 or 11' across, and I hold the base down with 4 50# bags of filter sand. I should bolt it to the deck but I dont....It works PERFECTLY because you can angle the umbrella more and more as the sun goes down. It's a mesh umbrella so it doesn't trap hot stuffy air either. Problem solved!
