Temperatures do not vary greatly throughout the year, though there are seasonal variations. Average temperatures range from high 80’s (F) to the mid 60’s (F) with little rainfall and seasonal breezes and fog. 

The warm season occurs from December though May and is characterized by hot sunny days, periodic rain showers, warm water and calm seas. The cool season occurs from June through November and is characterized by warm days, no rain, fog and trade winds. Find more detail on Galapagos Islands seasons.

Weather in the Galapagos Islands is attractive to adventure travel and small ship cruising year-round. Conditions can change dramatically over short periods of time going from hot and sunny to rain showers or from windy to calm in a matter of minutes.

Depending on prevailing ocean currents water temperatures can vary as much as 10 degrees (F) on a single day, depending on your location in the archipelago.

Northern Currents

The warm Panama current from the north warms the water and brings sunny days with sporadic rains from December until May. The rain usually arrives in the afternoon, and often clears up by the early evening. The ocean water is more calm during this time making for ideal underwater visibility and optimal snorkeling. 

Southern Currents

From June to November, both the cool Humboldt and Peru currents from the south arrive and cooler weather predominates, but rain is uncommon creating comfortable hiking weather. Although seas are rarely rough, tradewinds cause the ocean to be choppier this time of year and a misty fog (garua) may linger into the day.

Galapagos Climate Monthly Highlights

June starts the dry season with relatively cooler temperatures. Giant tortoises migrate from highlands to lowlands for suitable nesting places. In July, blue-footed boobies and cormorants are active and whales can be observed off the western coast of Isabela Island. August brings, masked boobies, swallow tailed gulls and Galapagos hawks nest and court. In September, air temperatures are at their lowest. Penguins, sea lions and marine birds are active, with sea lion births becoming more common. In October, fur seals begin their mating period. Through October and November, the majority of sea lion pups are born (however visitors may see sea lion pups during most of the year).

Puerto Villamil Climate & Weather For Travelers

Puerto Villamil, on Isabela Island is the westernmost settlement in the Galapagos and most influenced by the equatorial Cromwell current. Bringing rich nutrients from deep in the Pacific Ocean the Cromwell current is the principle reason why the marine environment surrounding the Galapagos Islands is so interesting.

In Puerto Villamil the cool season might be slightly shorter than the rest of the archipelago. Summers are hot and humid with calm seas.  Winters are cooler with fog, trade winds and cooler water temperatures.

As ocean temperatures increase due to climate change the weather and climate in the Galapagos is increasingly unpredictable. The delicate balance of life in the Galapagos and the crucible of evolution that occurs there has always been at the mercy of ocean currents. As those systems are increasingly disrupted the islands are subject to even greater evolutionary pressures. Species must adapt or die out. Scientists agree this process is speeding up.

Researched published in 2014 indicates that rising ocean temperatures are making El Nino weather patterns more frequent and more intense. The United Nations educational and cultural agency warns the Galapagos are one of the places most vulnerable to climate change.  Dive deeper into the effects of climate change in the Galapagos with this New York Times article

The typical traveler will not notice the changes described above. The Galapagos Islands, to the casual observer, appears rich, diverse, wild and pristine (because it is). Travelers should be aware of the issues and challenges of the islands and the impact of Galapagos travel. Most Galapagos small ship cruises will tackle this subject head on by educating travelers about climate change in the Galapagos and its effects on the wildlife and ecosystems. 

Rather than take a doomsday approach to see it before it’s gone, we hope you will visit and fall in love. Only when you love a place are you motivated to protect it. Changing our behavior to help reduce climate change to protect the Galapagos and its wildlife will do us all some good.
