Marine Reservation
The Marine Reservation according to a Ministerial Order of January 20, 1999 (THE BIGGEST OF EUROPE) of Graciosa Island and Small Islands of the North of Lanzarote it occupies 70.700 has and spreads in the Atlantic one including the area that includes the islets and roques to the north of the island ( la Graciosa Island, Montaña Clara, Roque del Oeste, Alegranza, Roque del Este and North coast) " it forms one of the most relevant marine habitats of the Canary Archipelago, considering its peculiar average environmental, not alone patrimony for its vulcanology and sceneries but also for its enormous biological wealth in species florísti endemic flora and marine species.

The marine environment of the Reservation is influenced by the laundering of cold and rich waters produced on the near coast African and responsible to a great extent for the fishing wealths of the zone, together with the extensive continental platform that it does that the funds are slightly deep and therefore illuminated enough.

Its slightly deep privileged funds (which the most western islands lack) are abrupt as it corresponds to a few volcanic islands, with cannons and tunnels but of crystalline waters sheltering species of faune and flora that we will not be able to see in any other place of the Canary Isles.

Climatology
As the rest of the Canary Islands, the Small Islands possess the privilege of climatological benign conditions, for the anticyclone of The Azores, where there originate the winds trade winds of origin north - north-east that dominate in the archipelago great part of the year, and for the cold current of Canaries, descending branch of that of the Gulf, which thinks up in direction south - south-west and which has a regulatory effect of the temperatures.

It is not usual for the precipitations to go on from 200 mm. annual. It is usual for rains to coincide with the presence of tempests in the winter centering at a few hours and days a year. The winds indicate the most determinant features of the climate of La Graciosa Island. Inside the north slope of Lanzarote, exposed to the winds trade winds (N-NE), it is in the summer months when his presence is major.
The element most typical of the sea in the zone, it is its situation, in the step of the cold current of Canaries, which propitiates a few more fresh temperatures of those who would correspond for geographical situation, with few seasonal changes.
