I suppose there are 2 main factors that can determine when is the best time to visit the Galapagos Islands - the weather and what wildlife you will see
If you are concerned about what the weather will be like, the archipelago is governed by two distinct seasons. While both offer exceptional wildlife encounters, the “vibe” of your trip will change depending on when you go.
The warm season is considered to be from December through May. The sky is a brilliant, piercing blue, punctuated by occasional, dramatic afternoon rain showers that keep the islands lush and emerald green. During this period, the air temperature hovers between 25°C and 30°C, and the water is at its warmest and clearest. So this is the best time to visit Galapagos if your priority is comfort and relaxation. The seas are at their calmest, making for smooth navigation between islands—a crucial factor for those who prefer a steady deck. Snorkeling during these months is an effortless joy, requiring no wetsuit as you glide over coral reefs teeming with colorful tropical fish and playful marine iguanas.
June through November is considered the cool season. That is when the Humboldt Current arrives from the south, it brings nutrient-rich, cooler waters. This is when a misty, ethereal fog often blankets the highlands, creating a mysterious and atmospheric backdrop for photography.
While the water temperatures dip to between 20°C and 23°C, the biological payoff is immense. The nutrient surge triggers a massive explosion of marine life. So this is the best time for a Galapagos cruise if you are an avid snorkeler and it is the only time of year when you can reliably encounter whale sharks near the northern islands and watch the sea lion colonies burst into life with newborn pups.
If seeing wildlife is more of a concern for you, then here is a month by month breakdown about what you might expect:
January is when the islands are at their most vibrant. The land iguanas on Isabela Island begin their mating rituals, appearing like miniature dragons amidst the greening vegetation. For travelers, January offers the perfect balance of warm weather and the exciting start of the green sea turtle nesting season. It is a time of renewal, where every shore excursion feels like stepping into a brand-new world.
February is arguably the best month for those who love the water because the sea is exceptionally calm and the clarity is superb. On islands like Santa Cruz and Española, marine iguanas become strikingly colorful—donning shades of red and green to attract mates. It is a visual feast that is best enjoyed during a guided coastal walk.

March is when the “wet” season is in full swing, but the rains are short-lived and serve only to cool the air. This is a magnificent time for birdwatchers. Frigatebirds, with their iconic red throat pouches, begin their elaborate displays.
April marks the return of the Waved Albatross to Española Island. These majestic birds, which spend most of their lives at sea, arrive to perform their clattering, sword-fight-like courtship dance. To witness this rare spectacle in person is a privilege few travelers ever experience, making April a high-demand month for cruises.

May starts the transition toward the cooler season and offers the best of both worlds. The water is still warm, but the breezes are beginning to freshen. This is the peak of the Blue-footed Booby’s courtship dance. Their rhythmic “high-stepping” is both comical and captivating, providing endless entertainment during island landings.
June sees the arrival of the trade winds and the nutrient-rich currents. The islands begin to shift from green to a more volcanic grey and brown, but the sea comes alive. This is the start of the whale shark season in the far north and you need to be on a cruise to get there.
July is when the waters around Isabela and Fernandina islands become a hive of activity. This is the best time to spot the Galapagos Penguin and the Flightless Cormorant. The cooler water means these birds are highly active, hunting for fish right alongside snorkelers. The weather is invigorated and fresh, perfect for long hikes across the dramatic lava fields.
August is when to come if you are looking for “cute” wildlife. This is the peak of the sea lion pupping season. The beaches are transformed into nurseries where curious pups often approach travelers (under the watchful eye of their mothers). You can sense the energy on the islands is and the cooler air makes the uphill treks to volcanic viewpoints incredibly pleasant.
September is the heart of the “Garúa” season when the mist creates a soft, diffused light that professional photographers crave. The marine life is at its most concentrated so you might find yourself snorkeling in a “soup” of tropical fish, sea turtles, and playful penguins. It is the most “wild” the Galapagos ever feels and is when the sea is normally the most turbulent.

October is a fantastic time to observe lava herons nesting. The islands feel quiet and exclusive during this time, allowing for an even more intimate connection with the environment.
November is when the water begins to warm up again, but the marine abundance of the cool season remains. Sea lion pups are now old enough to be extremely playful in the water, making for some of the best snorkeling encounters of the year. It is a month of high activity.
December brings the return of the clear blue skies. The giant tortoises begin their nesting season, and the islands prepare for the tropical bloom once again.
