Hobie's surfboard gets caught on a piling when he attempts to shoot the pier. When he comes up on the beach and stops next to Landon, he picks up his surfboard from the sand. How did it get there?
Just before Summer spots Courtney and Tiara drinking, she is barefoot. As she walks over to confront them, she is suddenly wearing flip-flops.
When Mitch and Hobie are talking on the beach at the end, a number of extras walk by, then disappear when the camera angle changes.
When Hobie stops his skateboard by the liquor store, a woman in a blue bikini carrying an orange-and-white towel can be seen walking behind him in the distance. This same woman then walks out of the store in his direction, and in a later shot is seen behind him in the distance again.
The kids play a Street Fighter II arcade machine, but the audio is from the Super NES version of the game.
Summer meets Courtney and Tiara as though for the first time. She then mentions them to no one until she talks to Jackie, yet somehow knows they are the two most popular girls at the high school she hasn't started attending.
Summer forgot to set the parking brake on her truck, when she helped Mitch rescue Hobie. Yet the truck conveniently stops on its own - just before entering the surf, and after just missing an oblivious sunbather - which makes the whole situation insultingly contrived.
