The weather temperature varies during the year:
June to December - From June to December the southern trade winds bring the colder Humbolt current north to the Galapagos. This means that the water is cooler, and a layer of high atmosphere mist pervades the island skies. In effect, the highlands of the larger islands are kept green and lush, while the sea level islands and shorelines have little precipitation.
Thus, June to December is generally called the "dry season" known for its blue skies and mid-day showers.
During this season tourist may observe a big amount of species around the islands or the sea such as: giant tortoises, Humpback whales, blue- footed boobies, cormorants, oystercatchers, lava lizards, Galapagos hawks, masked boobies, swallow tailed gulls, sea lions, lava herons, brown noddies, penguins, etc. Due to the water temperature it is the perfect time for diving.
