The Climate of Fuerteventura
The island's volcanic mass is over 20 million years old, eroding over this period to result in its current form of rounded hills and flattened peaks. The land on Fuerteventura is essentially desert, without the topographical diversity associated with changes of altitude seen on other islands such as Gran Canaria or La Palma.
Low precipitation (with rainfall of less than 200mm a year) helps contribute to the extreme aridity of Fuerteventura and its vegetation-free hills, a disposition exacerbated by a high degree of sunshine (over 3000 hours per year) and high winds that whip across the island, increasing evaporation and stripping moisture from the soil. All of these effects contribute to the island's Martian-like landscape, which varies little from one season to the next.
Trees find it hard to prosper or find good purchase on the island and much of the vegetation is scrub, which goats feed on. You will see lines of palms that have been planted by hand, but these are watered artificially through irrigation and would not survive without human intervention.
Fertile and lusher areas such as Betancuria display a richer degree of plant cover, but much of the island is sun-baked, stark and raw.
