Obviously, Portugal has a great climate, but the Algarve is a special area within Portugal. It is separated from the rest of the country by a mountain range that reaches up to 902 meters (in Foia near Monchique) and thus its always warmer than the rest of Portugal. In the months from November up till April, the Algarve has almost 3 times as many hours of sun as London or Amsterdam and only half the number of rainy days. Plus the sun is much stronger than in the north of Europe, you can get a sun tan in winter and you will need a hat. Temperatures are very pleasant, the average maximum temperature in winter is 18C, average minimum temperatures is still 14C degrees.
