The best time to visit the Galápagos Islands is truly any time of year—each month reveals a different side of this extraordinary archipelago. Straddling the equator, the Galápagos offers a rare blend of biodiversity and climate stability, making it a dream destination for nature lovers and wildlife enthusiasts alike. Still, your experience will vary slightly depending on when you go.

This seasonal guide will help you plan your Galapagos cruise or land-based adventure based on key factors such as weather, sea conditions, and wildlife activity. The islands’ fauna is ever-present, but their behaviour shifts with the seasons. Some months offer the chance to witness delicate hatchlings emerge from sandy nests, while others showcase dramatic courtship rituals—like the comical foot-stomping dance of the blue-footed booby or the elegant bill-clacking of the waved albatross.

If you’re eager to snorkel or kayak in warmer waters, the wet season (December to May) delivers with higher sea temperatures and calm conditions. On the other hand, divers often favour the cool, dry season (June to November), when the Humboldt Current enriches the waters, drawing in a dazzling array of marine life. Ultimately, the best time to go depends on your personal interests—whether you’re drawn to specific activities or hoping to encounter a particular Galápagos species.

The Warm and Humid Season: January to May

This season is marked by clear skies, warm temperatures, tropical showers, and lush, vibrant landscapes. Water conditions are ideal for swimming and snorkelling, with sea temperatures ranging from 23–26°C (73–79°F). On land, many species are nesting, mating, or hatching, making this a time of exceptional wildlife activity.

The Cool and Dry Season: June to November

Influenced by the Humboldt Current, this season brings cooler air and sea temperatures, misty skies (garúa), and rich nutrients to the waters. While snorkelling requires a wetsuit (water temps can dip to 19°C/66°F), it’s the best time for marine activity, especially diving. On land, mating and nesting behaviour intensifies among seabirds and reptiles.

• Water temperature: 22°C (72°F)
• Average rainfall: 5 mm (0.2 in)

Sea lion pups are born across the islands—expect plenty of activity in the rookeries. Humpback whales can sometimes be spotted migrating through. Galápagos penguins are seen darting in cool currents, while marine iguanas graze on underwater algae beds. It’s one of the most active months for seabirds and marine species.

August

• Air temperature: 23°C (74°F)

September is low season for tourism but high season for marine megafauna. Whale sharks appear near Darwin and Wolf Islands, and marine life is at its most abundant. Sea lion pups are playful and learning to swim. Flightless cormorant chicks are growing, and Galápagos penguins are at their most active. It’s a diver’s dream.

October

• Air temperature: 25°C (77°F)
• Water temperature: 21°C (70°F)
• Average rainfall: 8 mm (0.3 in)

Fur seals continue their breeding season, and blue-footed booby chicks can be seen across North Seymour and Española. Land iguanas become more visible as temperatures begin to rise. With fewer tourists, it’s one of the most tranquil times to explore. Ideal for quiet wildlife encounters and underwater photography.

November

• Air temperature: 26°C (78°F)
• Water temperature: 22°C (72°F)

The warm season begins, bringing back lush vegetation and more sunshine. Green sea turtles start nesting on beaches, while Darwin’s finches and other land birds begin courtship and nesting. Marine iguanas become more vibrant in colour as their breeding season begins. Water clarity improves, making it an excellent time for snorkelling, and the pleasant weather makes December a favourite month for travellers.

The Shoulder Seasons: May, September & December

The shoulder months of May, September, and December strike an exceptional balance of pleasant weather, active wildlife, and lighter visitor traffic—making them a favourite among travellers seeking a more nuanced Galápagos experience. It’s important to note that 97% of the Galápagos Islands is protected as part of the Galápagos National Park, with strict limits on visitor numbers and carefully regulated access to designated sites. Even during high season, you won’t encounter typical tourist crowds. Most human activity is concentrated in just a few inhabited ports and surrounding areas, ensuring that the vast majority of the archipelago remains wild, unspoiled, and deeply immersive throughout the year.

Optimal Activities by Season

Snorkelling & Diving

The best time for snorkelling in the Galápagos Islands is from December to May, when the waters are warmer (23–26°C / 73–79°F), calmer, and visibility is at its clearest. These months offer excellent opportunities to observe sea turtles, reef fish, rays, sea lions, and even penguins in the water.

 For diving, the June to November season is preferred by experienced divers. The Humboldt Current brings cooler, nutrient-rich waters (19–22°C / 66–72°F), attracting larger marine species such as whale sharks (especially in September), manta rays, and schools of hammerhead sharks. Although visibility may be lower, the diversity of marine life is unmatched.

Kayaking & Paddleboarding

Kayaking is possible year-round and offers a peaceful, low-impact way to explore the Galápagos coastline and its diverse ecosystems. The warm season (December to May) provides the calmest sea conditions, making it ideal for paddling along lava cliffs, mangrove estuaries, and secluded coves where sea turtles, rays, and marine birds can be spotted up close. During the dry season (June to November), cooler air temperatures and overcast skies offer relief from the sun, and kayaking becomes a rewarding way to approach sea lion colonies, blue-footed boobies, and nesting shorebirds from the water.

Hiking & Wildlife Viewing

The cool and dry season from June to November offers the most comfortable conditions for hiking, with mild air temperatures and minimal rainfall. This period also coincides with major wildlife events, including giant tortoise migrations, seabird nesting, and the birth of sea lion pups. Trails are firm and easier to navigate, making it an ideal time for exploring volcanic landscapes and highland habitats.

Photography

April and May are particularly rewarding for photography. Following the rainy season, the islands are at their most lush and vibrant, with dramatic contrasts of green vegetation against black volcanic rock. These months also feature courtship rituals of species like blue-footed boobies, waved albatrosses, and frigatebirds, offering dynamic and unique subject matter. Clear skies and softer lighting conditions add to the appeal for capturing both landscapes and wildlife.

The Best Time to Visit the Galápagos Islands Is When Curiosity Calls

The Galápagos Islands offer unforgettable experiences year-round, with each season unveiling new wonders both above and below the waterline. You might find yourself snorkelling through crystalline waters alongside sea lions and penguins, kayaking past towering cliffs, or capturing the slow, deliberate steps of giant tortoises in the highlands. Trek across lava-sculpted landscapes where marine iguanas warm themselves in the sun, or stand in awe as blue-footed boobies perform their famous mating dance. From intimate wildlife encounters and volcanic hikes to pristine beaches and world-class diving, every month offers something remarkable.
