The Azores in February? Why not? There's lots to do and see all year round when visiting any of the islands in this beautiful archipelago. Not only that, but the weather is very good in comparison to most northern climates in North America or Europe. So if you are from Canada, the Northern United States, or much of Europe, a vacation to this mid Atlantic treasure is well worth considering. Especially if you enjoy any of the following activities ...
... then you should consider going this February.
Outside of the above reasons, the Azores in February is quite affordable. This is the low season so airfare and accomodation costs are quite low.
And the flight is fairly short from most of Western Europe and Eastern North America. the flight from Toronto is only 5.5 hours, and the flight from Boston is only 4 hours! It's even less from many parts of Europe.
If you live in Canada or the United States, the dollar is doing well against the Euro making this trip even more affordable in February 2012.
My personal recommendation would be to visit Sao Miguel and stay at Quinta das Acacias. All of the islands have a lot to offer and are incredible in their own way. But Sao Miguel has more to see and do as it is the largest and most populous.
Quinta das Acacias is a beautiful property with six self catering cottages. The owners, Bonita and Eduino, live on site and are great hosts. They take great pride in the property and have created a private oasis on their spacious grounds. Read more about Quinta das Acacias, my recommended accommodation in Azores
The weather isn't going to be hot like a Caribbean destination. But at a typical temperature in the mid to high fifties (55-60) with some days closer to 70 fahrenheit, this is a great place to get away from freezing temperatures at home.
