Just another GR refugee. Other than that, I had a stroke in 2004, and read almost anything I can get my hands on, though I have a particular weakness for history, mystery, and historical fiction.
I don't read on the beach; my knees are not up to it anymore, and the sun is too bright - I am a bit light sensitive. I do like to read on a porch at the beach, in the shade, with a nice cold Coke or a lemonade at my side. And when I do, I like a nice fat juicy read, possibly verging off into "guilty pleasures" territory, or something light and funny. (The 80s were a good decade for this kind of reading, actually.)
I had a whale of a time once at the beach with Spook: Science Discovers the Afterlife, by Mary Roach. (The bit about a 1928 North Carolina court which took testimony from a ghost had me rolling in the aisles.)
But I almost went with Judith Krantz's Princess Daisy. Just so you know.
