General information about the country
Portugal is a great country to visit for scuba diving. There is a lot of great diving that can be done off the shore of continental Portugal, but the real magic happens on the Azores and Madeira, its offshore island regions. There especially you can expect warm, crystal-clear waters and in many places: awe-inspiring flora and fauna, including manta rays.
Portugal consists of mainland Portugal, sandwiched between the west side of Spain and the Atlantic ocean, as well as 2 autonomous island regions, the Azores and Madeira, located hundreds of kilometers off of the coast of the mainland. The Azores are home to dozens of active volcanoes, many of which are underwater and produce spectacular rock formations.
The official language of Portugal is Portuguese. Only around a quarter of Portuguese citizens speak English, but in well-known tourist regions, you are likely to be able to get by with only English. About a quarter of the Portuguese speak also French, and about 10% speak Spanish (europa.eu, 2012).
Portugal is a warm and wet country, with temperatures averaging 16 C in the winter and 26 C in the summer, and usually only around 14 dry days in the winter (weatheronline.co.uk, 2018). Portugal experiences a strong rainy season in the winter, with as much as 12 times more rainfall than in the summer months (statista.com, 2017).
