Madeira’s sea has a pleasant average annual temperature of 21°C and a fasci-nating underwater world, rich in biodiversity of marine fauna constituted by fish, birds, reptiles and mammals. On the north coast, the sea has deep, rough blue waters with strong waves. On the other hand, the south coast has a peace-ful and transparent sea with calm waves.
It is worth mentioning the Garajau Marine Nature Reserve, located on the south coast, which was created with the purpose of protecting this privileged area of the Madeira’s coast.
The sea on Porto Santo Island has characteristics identical to those of the southern coast of Madeira, but it is even more transparent, and with an incom-parable turquoise colour.
Those who visit the sea of the Madeira’s archipelago can dive in an environ-ment surrounded by groupers and other kind of fish, or visit the artificial reef of the “Madeirense” boat sunk at 30 meters deep, which attracts the best divers in the world. The mild temperature of the sea will allow tourists to swim, surf, sail and practice stand-up-paddle, snorkelling and diving during the four sea-sons of the year.
One of the things Porto Santo is a well-known destination is its golden sandy beaches. Madeira Island is famous for its natural volcanic pools and pebble beaches (volcanic little stones) and black sand. In Madeira there are also some yellow sandy beaches (with imported sand) and several spas, with swimming pools and direct access to the sea. In addition, different beaches have blue flag, a certification of high quality standards.
One of the most emblematic images of Madeira Island is its natural pools. They are made of volcanic rocks; there the sea enters naturally, forming pools of salt water, thanks to the magnificence of the waves. The natural effects of the waves against the rocks are a sight to see; another wonderful natural spectacle that can be enjoyed on days when the sea is calm are the pools becoming real lakes, of-fering the sensation of swimming in the sea, but in a natural pool.
