Key Takeaways
September (Fall) is one of the best times for wildlife in the Galapagos - cool, nutrient-rich waters bring highly active marine life and unforgettable close encounters.
Expect mild, refreshing conditions - cooler air, overcast skies, and light Garúa create comfortable days for hiking, kayaking, and exploring.
Snorkeling is exceptional this time of year - while the water is cooler, visibility and marine activity are at their peak.
Fewer travelers, more intimate experiences - Fall brings quieter landing sites, more personal guiding, and deeper connection to the islands.
1. Galapagos wildlife and marine life are more active than ever with the presence of the Humboldt Current.
The Humboldt Current, also called the Peru Current, is a robust ocean current that flows west along the equator, bathing the Galapagos archipelago with new life.
In September, the presence of this current is strong, making nutrients in the water more abundant and marine life is more active. The result? A vibrant array of rare wildlife and marine life appear for this feast. Snorkeling anyone?
2. During this time, whale and dolphin watching is at its best.
Spotting whales and dolphins from the yacht deck, particularly on Quasar’s crossing to Fernandina Island, is very common. September brings with it guaranteed Kodak moments, as you bare witness to the graceful nature of some of the world’s largest sea creatures.
From seeing Humpback Whale calves riding on the backs of their mothers to seeing the Orcas’ agile jumping displays, getting up close and personal with whales and dolphins brings National Geographic to life right before your eyes.
3. You are guaranteed to see sweet sea lion pups.
There are few mammals cuter that California and Fur Sea Lion pups. You’ll see both when you visit the Galapagos Islands in September! This month is full breeding season for the archipelago’s sea lion population, resulting in some of the sweetest wildlife encounters of the year.
4. September is a bird-watcher’s delight, with some of the most vibrant Galapagos sea bird activity of the year.
In September, Great Frigate birds start mating. If you haven’t witnessed their beautiful courting displays, you (and your camera) are in for a treat.
Sea bird nesting is also very active in September. You’re likely to see majestic Blue and Red-Footed Boobies, quirky Flightless Cormorants, elegant Greater Flamingos, and torpedo-like Galapagos Penguins swimming at the surface. In this month, even the Brown Pelican comes out to play and display their trademark long, fish-gobbling bills.
