Do you have any information about the current demographics? 
 During the summer, the resident population in the city triples. This seasonal movement from neighboring cities is due to the draw of the beach and about 30% of homes had seasonal use in 2001. This was the highest in Greater Porto. 
 I did not! Can you share more about its history? 
 Wow, triples. Where are the residents traveling from? 
 You are welcome.
