July can be hot, with late-July being hotter than early-July. Crowds are pretty high around the 4th, though. Mid-June--cooler weather (June gloom), but there's Grad Nights and the park closes earlier a few days a week. Can also be crowded as kids are getting out of school. Easter--great weather usually (can be anywhere from low 70s to mid 80s), but again, pretty crowded. Christmas--colder, rain possible. The week before Christmas is crowded but managable, the week after, nuts--very crowded.
