Try this the next time you are in Nicaragua - get some of that really good, expensive sunscreen.  Explain to a local surfer that the sun is VERY STRONG in Nicaragua and that it's a good idea to put a little of this on your face before spending the whole day at the beach.  Make sure you watch them as they put on "a little".  Try not to laugh when they ask you "how do I look?".   Armando "El Codo" Lopez ladies and gentlemen.
