Thanks for the magicseaweed link. Clearly, I'm not the only person that wants to go surfing in October. Some promising options mentioned there and above so thanks for the tips.
I don't mind having my hand held on a fully managed week while I'm learning and still keen on Morocco so will look into companies like Surf South-West, Rapture, Africa Extrem(?), Morocsurf and others. Also considering Lanzarote, but not quite so appealing (if only for bragging rights at the new job!).
I have actually attempted to surf in the North Sea off Tynemouth in January and appreciate that the good waves don't always come with the warmer temps (in this country at least).
I think mangoridebike is having a bit of fun in suggesting I go to Cornwall. Probably been a long time since he's seen the sun up in Fort William so anywhere would be warm for him.
