When to visit the Galapagos: A wildlife calendar

The short answer

There is no single best time to visit the Galápagos. There is a best time for what you want to see.

Some months offer sun-warmed snorkel sessions with sea turtles and glassy water. Other months feel like the ocean has turned the volume up, with misty mornings, cooler swims and feeding frenzies offshore.

Use this wildlife calendar to line up your dates with the moments you actually care about.

December to June: warm seas, greener islands

You get warmer air and sea temperatures, brief showers and calmer water. The islands look softer and greener, and a lot of land-based nesting and hatching takes place.

June to November: cooler seas, richer water

You get cooler temperatures, garúa mist and stronger currents. Underwater life can be spectacular because cold currents bring nutrients to the surface.

Month-by-month Galápagos wildlife calendar

Each month has a mood, a sea state and a few headline wildlife moments.

January

The islands start to go green and the light is bright and clean after showers. Sea conditions are usually calm, with warm water for snorkelling. Marine iguanas hit peak colour during breeding. Green sea turtles begin nesting on beaches.

Good for: warm-water snorkelling and seeing the islands look lush.

February

Hotter days, warmer seas and a slow, summery feel on shore. Greater flamingos begin nesting on Floreana. Marine iguanas nest on Santa Cruz. Penguins drift west to cooler water, so sightings around Bartolomé can drop.

Good for: nesting activity and easy-going water time.

March

Humidity climbs and the sea is often at its warmest. Snorkelling can feel effortless, especially around the western islands. Waved albatross begin returning to Española late in the month. Frigate birds start their mating season on San Cristóbal and Genovesa.

Good for: warm water plus big bird behaviour.

April

Rain eases but the islands stay green, with softer colours and full-looking landscapes. Waved albatross gather on Española in large numbers. Green sea turtle hatchlings begin emerging. Land iguana eggs start hatching on Isabela.

Good for: a strong mix of land wildlife and comfortable sea conditions.

May

The transition month, still warm but with a hint that the seasons will shift. Marine iguana hatchlings begin appearing on Santa Cruz. Waved albatross start laying eggs on Española. North Seymour can be excellent for blue-footed booby courtship displays.

Good for: courtship, hatchlings and warm snorkelling days.

June

The Humboldt Current arrives and the sea begins to change character. Garúa season starts, with overcast skies and fine mist that can make mornings feel cinematic. Nutrient-rich water can lift marine encounters. Humpback whales can sometimes be spotted from June through to September. Giant tortoises on Santa Cruz begin migrating toward nesting areas.

Good for: richer marine life and the start of whale season.

July

Cooler swims, sharper air, and busy coastlines. Seabird breeding ramps up across the islands. Blue-footed boobies breed on Española. Flightless cormorants nest on Fernandina. Whales and dolphins are often easier to spot off western Isabela.

Good for: seabirds, marine mammals and a more expedition feel.

August

This is peak cool season energy, with colder water and serious underwater productivity. Sea lion pupping begins, which changes the feel of the beaches overnight. Galápagos hawks court on Española and Santiago. Nazca boobies and swallow-tailed gulls nest on Genovesa. Giant tortoises begin returning to the highlands after nesting.

Good for: sea lion pups, nesting colonies and strong marine scenes.

September

One of the coolest, mistiest months, often with fewer visitors. Penguins become more active around Bartolomé during courtship. Sea lions stay busy as males compete for dominance. Water is colder, so a wetsuit becomes part of the plan.

Good for: penguin moments, quieter travel and high-energy sea lion behaviour.

October

Mornings can start grey, then lift into warmer afternoons. Lava herons begin nesting. Galápagos fur seals begin mating. Blue-footed boobies can be seen raising chicks on Española and Isabela. Giant tortoises may still be laying eggs in some locations.

Good for: a blend of cool-season wildlife with comfortable temperatures for hiking.

November

A shoulder month that often feels like the islands are exhaling. Seas calm and snorkelling visibility often improves. Sea lion pups become bold and inquisitive in the water. Brown noddies breed and jellyfish can sometimes be seen.

Good for: snorkelling quality and playful sea lion encounters.

December

Warm season returns, with calmer water and rising temperatures. Giant tortoise eggs begin hatching and this continues through April. Green sea turtles may be seen mating in shallow waters. Young waved albatross fledge before leaving Española.

Good for: tortoise hatchlings, warm water, and early-season calm.

Planning tips from our team

Pick your month based on your priority first, then work backwards.

If snorkelling comfort is top of the list, you will usually prefer the warmer water months. If you want peak marine productivity and do not mind cooler swims, the cooler season can be brilliant. If you want specific wildlife moments, use the calendar above and choose dates with intent.
