I was going to come here and recommend Trebizon by Anne Digby. They were set more 1980s, there's a nearby boys school and there's definitely boyfriends and teen-appropriate romance. The series protagonist isn't Brilliant At Everything but is definitely brilliant in a couple of areas, and has to make a couple of difficult decisions about her school career as she gets older.
Also they are in Cornwall with swimming in the sea and surfing.
