Weather
Portugal (and it’s weather) is defined by the sea. Its history has been shaped by its proximity to the ocean and its position as the westernmost European nation. So it is today with its weather. A country of sublime climatic conditions, its temperatures are moderated by the Atlantic Ocean, never too cold and never too hot. Always just right, with a nice ocean breeze.
