I'm planning a trip to California for August. I'm planning on driving around and I hope to include the Grand Canyon, Yosemite National Park and San Francisco. I'd also like to spend a few days on the beach, but I'm concerned that it might not be warm enough in California where temperatures seem to be around 68F/19'C, and I'm not sure about humidity.
Can anyone recommend a good location where my (older) family could enjoy a few days lying on the beach? I don't mind travelling so long as it fits in with the rest of my plans. I did look at flying over to Hawaii but it seems like it might be a bit too much of a hassle logistically.
