We carry rain jackets and pants in our back packs. If it gets cold we put them on. Its nice for braking the wind if it comes up and not to heavy. We have been their in December when it was so cold we were wearing sweatshirts and heavy winter jackets with gloves and stocking caps, makes for funny pictures. At best take a sweatshirt and panchos if you have them. Air conditioning can get you sometimes in restaurants. Take two pair of shoes if it rains your shoes will be wet.
