The islands are isolated, so the climate is, determined almost entirely by the ocean currents, which in turn are influenced by the trade winds which push the currents.   The Galapagos is a major intersection of several currents, which vary in intensity during the year as their driving trade winds blow and then weaken in a cycle that gives two distinct seasons to the islands.   These currents also control the pattern and variety of Galapagos plant and animal life.

The climate of the Galapagos Islands is unusually dry for the tropics.  There are two main seasons, each of which has a dramatic effect on the vegetation.

  • From January to June, air temperatures are warm and the skies are usually clear with occasional heavy rain showers.   This is known as the warm/wet season, and the winds from the east prevail, and the sea is gentler.
  • From June to December, the air is cooler from 24 to 16°C, the skies are often lightly overcast or cloudy, and there is virtually no precipitation in the lowlands, while the highlands are almost continually wet with light rain “showers” called “garua”.  This period is referred to as the garua or cool/dry season. Prevailing winds are from the southeast and the sea is often choppy.
