November it´s a great time to come to Porto. Friend??? About speaking portuguese, thta´s a real tough language to learn but you will learn fast, i hope . You will always found someone that know english, dont worry about that, and i can go and meet you and take you to the best places of the beach. B) 1 dollar=3 real, and things in here are too cheap, you can exchange money in the US, but check it out, i dont know for sure about this. Dont worry about sun dresses, you gotta bring all you have. It will be very hot at that time. About school, Porto´s school are bad...public school in Brazil sucks, you gotta put your kid in a private school and we have a lot of good private schools. Porto is a beach that people just go there to pass the weekends and vacations. The kids in here plays soccer all the time and exist some tournaments.
But, i still dont believe that you are coming in here.
