The Galapagos - When to Go

The Galapagos Islands can be visited year-round, there is really no "best time".

The warm rainy season is from January to June and this is the best time for snorkeling, with warmer water temperatures. Dry season is from July to December.

High season in the Galapagos tends to be from mid-December through January and June to August, when most vacationers arrive.

Climate & Weather

The Galapagos Islands have a subtropical climate regulated by the cold Humboldt current and the warm El Nino current. The islands are located at this intersection of these currents which result in the weather changing its intensity during the year as the currents' driving trade winds blow and weaken in a cycle that gives two distinct islands and control the pattern and variety of Galapagos plant and animal life.

The weather varies during the year. From December until May temperatures range from low to upper 80's (with possibilities of rain). From June to September temperatures vary from low 60's to high 70's. This is the Garua season (mist in the mornings). From October until December temperatures range from 70's to 80's (dry season).

Water Temperatures

The water is cold. It is recommended that you wear a 5 to 7 mm wetsuit, hood and gloves for diving and snorkeling. Most vessels in the Galapagos rent wet suits to their passengers. Be sure to inquire for your specific vessel.

The water around the islands to the north is warmer, while the central and southern islands have colder water. West of Isabela the waters are very cold. There are often thermo clines between 10 to 30 meters deep. During an El Niño phenomenon the water temperatures can rise significantly.
