Surfing is not really an issue for the majority of students! Really it is not. The few that surf go to Falmouth.
Surely you start looking for courses that are suitable for the subjects a young person likes best. Therefore, if it is sciences, look at pure science but also applied science such as Engineering. If he likes Geography you could consider the huge variety of Geography courses but there is also Planning and courses that are more about the environment.
He will also need to have some idea about which university is in reach. Is he likely to be AAA or CCC? This will hugely impact on where he can apply and what he can study. There are many choices for AAA but far fewer for CCC. Does he want a course leading directly to a job, eg nursing, or teaching? Is he happy to do a standard subject, eg English, History, Languages etc and see where life takes him? Does he want a research led university, or a more vocational course with a year in industry? The newer university are good for these. You presumably know that not all universities or courses are rated equally.
It would help to know what his interests are. He must also have some idea of whether he wants a big lively city, eg Manchester, Sheffield, Leeds, Newcastle, Bristol, or whether he wants quieter places and campus universitites, Loughborough, Bath, Surrey at Guildford for example. Travel home may be an issue if it is hundreds of miles from home but really this should not be a deciding factor above everything else. How often is he intending to come home? The students that tend to come home are the ones who do not settle and have chosen the wrong place. Student life should be more interesting than home for the weeks they have to be there.
I do know people who have prioritised certain universities, eg Newcastle for the nightlife, Loughborough for the sport etc and then checked what courses are on offer that they could do. His A level subjects will be a guiding factor but so are external interests. What does he do in his spare time? What can they lead to?
