Galapagos Islands Weather

The Galapagos weather despite their tropical location is not so warm because the islands are surrounded by relatively cold waters brought northwards by the Humboldt Current. The Galapagos Islands has two main seasons, each of which has an effect on the flora and fauna: the warm and wet season from January to June and the cool and dry (garua) season, from July to December. During the "garua" season, cooler waters from the Humboldt Current are driven to the Galapagos by the southeast trade winds.

January to June
Temperature	80ºF to 90ºF	(27ºC to 32ºC)
Water temperature	70ºF to 80ºF	(21ºC to 26ºC)

July to December
Temperature	70ºF to 80ºF	(21ºC to 27ºC)
Water temperature	65ºF to 75ºF	(18ºC to 24ºC)

As a result, there is warm tropical air passing over cool water. The moisture evaporating from the sea is concentrated in an inversion layer (300 to 600 m above sea level) and the higher parts of the islands, which intercept this layer, receive precipitation in the form of garua (mist rain). While lowland areas remain dry though cool.
