The official language in the whole country is the Portuguese, a language with Latin roots quite easy to understand if you speak already Spanish, Italian or French. If you don’t speak any of these languages don’t freak out! In most of the touristy places they know and speak English, the only reall language challenge will be in the small villages and traditional sites.
In Algarve, exactly the same than in the South of Spain, they have high and warm temperatures the whole year, which makes it an ideal destination for all those who search for a hot-warm weather. Despite Algarve is located in the Athlantic Ocean, the weather is more Mediterranean. Sunny days, smooth temperatures in the Winter and hot Summers, always calmed by the Athlantic breeze. In the region it doesn’t rain a lot, but when it rains it does it mostly during the Winter, from November to February.
