I can confirm the surf in Lisbon is awesome and a massive variety of beaches near the city. Not sure of the tech scene though. Ireland has awesome surf if you don't mind the cold.
Bristol, Oxford, Cardiff and Swansea in the UK are all in good positions to get to the coast. 2/3 hrs and lest than 1 hr respectively and decent chance of work.
If you have a chance of remote work consider Morocco!
