Route 762 will lead you to Route 763 which goes to Breezyshore Beach. Once again, it's an ocean terrain so you'll need a Water Pokemon with Surf. The weather is usually clear but may rain on occasion. Once again, a little rain won't hurt you at all. It is also filled with teh typical Pokemon from Chinchou, Carsila, Staryu, Caravahn, Marill, and Magikarp.
Good luck, Pokemon Trainers.
