The natural marvels of the Galápagos are truly endless—from its famed wildlife to its otherworldly volcanic landscapes. This spectacular destination is a must-see for nature lovers and curious travelers alike.
Before you get up close and personal with species found nowhere else on Earth, this month-by-month guide will help you learn more about the islands’ weather patterns and equatorial climates so you can prepare for your visit, no matter what time of year you decide to explore.
Complete with travel advice from the experts at Lindblad Expeditions, the company who pioneered expedition travel to Galápagos back in 1967, this comprehensive guide breaks down all you need to know about Galápagos weather, seasons, water temperature, rainfall, and Galápagos Islands wildlife.
The Best Time of Year to Visit the Galápagos
One of the most wonderful things about the Galápagos is that it is magical all year round, says Emma Ridley, Expedition Leader for National Geographic-Lindblad Expeditions. “The main difference is the land and water temperature, so the best time for Galápagos trips is really whatever suits your personal preference,” she says.
The majority of animals are active throughout the whole year so anytime you arrive you can encounter a wide range of incredible species, including sea lions, marine and land iguanas, lava lizards, giant tortoises, green sea turtles, red- and blue-footed boobies, Galápagos penguins, flamingos, Darwin's finches, Galápagos hawks, and much more.
However, Ridley explains that the climate in Galápagos fluctuates between the cool, dry season with productive waters which fuel the marine ecosystems, and the hot, humid season with warm, nutrient-poor waters that lead to rains which fuel the terrestrial ecosystems.
The life cycles of the wildlife are tied to this fluctuation, she says, and that means different months have specific highlights, which you can look at below. Some species breed throughout the year, like magnificent frigatebirds and swallow-tailed gulls. Many other species that have more defined breeding seasons can also be found breeding throughout the year, such as red-footed boobies, Galápagos penguins, and sea lions.
Let’s start with the month of May, which many experts at National Geographic-Lindblad Expeditions agreed is a very enjoyable time of year for Galápagos Islands cruises.
May in the Galápagos Islands
“I think my favorite time to visit the islands is between May and July,” says Naturalist Ramiro Adrian. “The water is warm for snorkeling but cold enough to allow nutrients in the sea to activate the marine ecosystems and their dynamics, like marine bird reproduction, sea lion display, and Pacific sunfish feeding.” That means it’s possible to see an abundance of colorful fish and lively sea lions.
Galápagos Weather in May
- Galápagos high temperature in May: 82 degrees Fahrenheit (28 degrees Celsius)
- Average Galápagos water temperature in May: 74 degrees Fahrenheit (23 degrees Celsius)
- Average Galápagos rainfall in May: 0.6 Inches (1.5 Centimeters)
Best Things to Do on a Galápagos Cruise in May
- Water temperatures are still warm enough to enjoy long snorkeling sessions with abundant sea life like sea lions, sea turtles, and manta rays.
- Since the weather is dry and the air temperatures are cooler, it’s the perfect conditions for long nature walks.
Wildlife You’ll Likely See in the Galápagos During May

Waved albatross, known for their fascinating mating dances which feature lots of honking and bill clacking, are beginning to lay eggs on Española Island. Blue-footed boobies, also known for their comical mating ritual that includes showing off those vibrant blue feet, are starting their mating season. The water is still warm, and although the air is balmy, there is a breeze that makes the weather very pleasant in June, says Naturalist Gilda Gonzalez.

Best Seasons to Visit the Galápagos Islands
The best time of year to take a Galápagos cruise is heavily dependent on what you wish to see and tour on the islands. As you’ll see below, there are three main Galápagos seasons.
Galápagos Warm Season (Galápagos Rainy Season)
Galápagos in summer, which is January to April, brings the hottest and most humid weather, creating a tropical environment. The waters are warm and clear, making the warm season ideal for snorkeling and scuba diving, and the lush islands are teeming with active land animals.
Galápagos Cool Season (Galápagos Dry or “Garua” Season)
June to November is considered the cool season in the Galápagos Islands. Many consider these months to be some of the best for wildlife viewing, as most of the animals are mating and producing offspring, which creates exciting activity.
The waters are also colder and therefore nutrient rich, which attracts a larger variety of sea life — although the visibility is less than in the warm season when the water is clearer.
Galápagos Transition Seasons
May, December, and September are considered off (or shoulder) seasons in the Galápagos Islands. Some think these three transition months can be the best times to visit the islands, as the weather is mild and you can benefit from some of the perks of both major seasons.
Daylight Hours in Galápagos
Due to the archipelago’s equatorial location, the sun varies by two degrees year round, which provides an average of 12 hours of sunlight each day. Sunsets here can be exceptionally dramatic and beautiful, providing some incredible photo ops.
Galápagos Islands Water Temperature
Just like the air temperature, the water only varies by about 10 degrees throughout the year. The warmer waters tend to be clearer. Colder temperatures have less visibility due to the abundance of nutrients that come from upwellings.
Regardless of the time you choose to explore, you will be able to snorkel in comfort if you gear up properly with a protective wetsuit. If you travel with National Geographic-Lindblad Expeditions, wetsuits are provided for every guest aboard to use for the duration of their voyage, making it seamless and easy.
January | February | March | April | May | June | July | August | September | October | November | December | |
Average rainfall (inches) | 2.0 | 2.6 | 3.3 | 1.4 | 0.6 | 0.1 | 0.2 | 0.2 | 0.3 | 0.3 | 0.2 | 0.3 |
Average high temperature (fahrenheit) | 84 | 86 | 88 | 86 | 82 | 78 | 76 | 74 | 76 | 77 | 78 | 80 |
Average low temperature (fahrenheit) | 70 | 74 | 77 | 72 | 72 | 68 | 66 | 64 | 62 | 64 | 66 | 68 |
When Is the Best Time to Go Snorkeling in Galápagos?
Sea life is most active when the water temperature is cooler from June to November. This is due to the fact that deeper, more nutrient-dense water can more easily rise to the sunlit surface areas, attracting wildlife.
If snorkeling Galápagos in less brisk conditions is what you’re hoping for, opt for December to May, when the visibility is better and you can spend more time in the water looking for fascinating Galápagos marine life.
Worst Time to Visit Galápagos
When it comes down to it, there is never a bad time to visit the Galápagos because there is always so much happening every time of year. As Ridley sums it up:
“Choose a time of the year according primarily to your climatic preferences. If spending a lot of time in the water is an important motivator, then the hot season might be best. If hot, tropical conditions on land are not well tolerated, then the cooler season will be a lot more pleasant. It is important to note though that the boundaries between the seasons are blurring more and more, like in most parts of the world, and there seems to be longer hot seasons, so there are no real guarantees.”
Bottom line: With the archipelago’s unique equatorial location, year-round breeding and migratory patterns, and mild temperature changes, a Galápagos cruise will offer an exciting adventure whenever you choose to explore.
