When is the best time to visit the Galápagos?

A local's guide to the warm and dry seasons, month-by-month weather, wildlife calendars, and which tours to book in each season.

🌦️ The Two Seasons of the Galápagos

Warm & Wet Season (December – May)

Warm days between 22 and 31 °C (72–88 °F), brief tropical showers followed by sunshine, and the ocean at its warmest and clearest — 23 to 28 °C (73–82 °F). The islands turn green, land wildlife is at its most active, and the sea is calm enough that even reluctant sailors enjoy the boat rides.

Best for: snorkeling in warm water, first-time visitors, families with kids, anyone prone to seasickness.

Cool & Dry Season (June – November)

The Humboldt Current arrives loaded with nutrients, cooling the ocean to 19 to 24 °C (66–75 °F) and pulling in huge schools of fish, rays, sharks, whales, and dolphins. Air temperatures are a comfortable 18 to 26 °C (64–79 °F), skies carry the misty garúa drizzle in the highlands, and the sea gets a bit choppier.

Best for: divers and marine-life fanatics, penguin spotters, comfortable hiking weather, and travelers hunting lower prices.

📅 Month-by-Month Cheat Sheet

🐢 Wildlife Calendar: Time Your Trip Around the Animals

Here's the good news: almost nothing migrates away from the Galápagos. Giant tortoises, sea lions, boobies, iguanas — they're home all year. Only one resident keeps a strict calendar, and it's a big one.

The waved albatross nests only on Española Island, and only from about April through December. If seeing the world's largest tropical seabird perform its clacking, bowing courtship dance is on your list, plan for those months and book the Española Island Tour from San Cristóbal. From January to March, they're out at sea — no tour can fix that.

A few more seasonal highlights and where to catch them:

• Galápagos penguins (best July – September): cooler water brings them closer to the central islands. Your best encounters are around Bartolomé on the Bartolomé – Sullivan tour or Las Tintoreras on the Isabela day trip.
• Sea lion pups (born August – September, playful October – November): they'll photobomb your snorkel session at La Lobería and Las Grietas in Santa Cruz or on San Cristóbal's 360° Tour.
• Frigatebird courtship (peaks May – June and November): males inflate their scarlet throat pouches like balloons on North Seymour – Bachas.
• Giant tortoises and flamingos (year-round): hatchlings appear December onward at breeding centers. On Isabela, one tour combines the Tortoise Breeding Center, Flamingo Lagoon, and Wall of Tears.
• Rays, reef sharks, and sea turtles (year-round, clearest water December – May): the lava arches of Los Túneles at Cabo Rosa are as close to an aquarium as the open ocean gets.

🤿 Best Time by Activity

Snorkeling & swimming

December to May wins for comfort: bathwater temperatures, glassy seas, and superb visibility. Head to Los Túneles, the 360° Tour, or Las Grietas. From June onward the water cools but fills with life — a shorty wetsuit (most tours provide one) keeps you happy.

Wildlife watching & birding

Honestly? Any month. For bird density, North Seymour – Bachas, the 180° Tour on San Cristóbal, and Española (April – December for albatrosses) are hard to beat.

Hiking & volcanoes

The cool, dry season (June – November) is ideal for the long ones — like the 16 km round trip across the rim of Sierra Negra and Volcán Chico, one of the largest volcanic calderas on Earth. In the warm season, start early and bring double the water. The steamy Sulfur Mines trek rewards hikers in any month.

Quiet beaches & fewer crowds

September to November is low season: the same wildlife, softer prices, emptier trails. It's a lovely window for slower trips like Pinzón – La Fe or a Floreana day trip.

🚤 One Local Heads-Up: Sea Conditions

If your itinerary hops between islands, the ocean matters. December to May brings the calmest crossings; June to November gets choppier as the trade winds pick up (nothing dangerous — just bring seasickness pills if you're sensitive; we wrote a whole guide to surviving the ferry). You can book inter-island ferries here, or let an island hopping package handle the logistics for you.

🎒 Packing, Briefly

Year-round: reef-safe sunscreen (SPF 50+), hat, polarized sunglasses, sturdy sandals or trail shoes, swimsuit, refillable water bottle, and a light rain shell. Warm season: extra swimwear and long sleeves for sun protection. Cool season: a windbreaker for boat rides and a shorty wetsuit if you run cold (many operators lend them).

✅ So… When Should You Go?

• Want warm, calm, postcard weather? → December to May.
• Want maximum marine life and penguins? → June to November.
• Want albatrosses? → April to December, on Española.
• Want the best deal? → September to November.

Whichever season calls you, the islands will show off.
