September in the Galapagos is perfect for enjoying the calm of the low season, along with reduced rates and especially lively wildlife. My wife and I loved how peaceful the islands felt, letting us soak in the unique atmosphere without the usual crowds.
One of the highlights of September is the chance to see Galápagos fur seals sharing the shores with adorable sea lions and their pups. We headed to Isabela Island and San Cristobal Island, where we watched them lounging on sidewalks, occupying stretches of beach, and even catching glimpses of their mating rituals. It was an incredible sight that made September feel like a truly special time to visit.
September is a fantastic month in the Galapagos, especially for penguin lovers and those hoping for a last glimpse of humpback whales. My wife and I took the opportunity to snorkel with penguins around Bartolome Island, and the experience was unforgettable. Afterward, we hiked up to Pinnacle Rock, where we were rewarded with breathtaking views of the sea.
We also spotted penguins during our Los Tuneles tour and while snorkeling at Concha Perla on Isabela Island. With all these unique experiences, September truly showed us why it’s such a great month to visit the Galapagos.

In September, the Galapagos skies can vary between bright and overcast, with the occasional light drizzle, even though it’s one of the driest months. We found the mild temperatures refreshing, and the cooler, drier weather was perfect for exploring the islands comfortably.
This kind of weather is a nice alternative to the warmer, more humid conditions of the rainy season, and we appreciated the balance it offered. For us, September’s climate made outdoor activities more enjoyable and kept the days feeling pleasant and relaxed.
Galapagos in September: Wildlife
One of the highlights of visiting the Galapagos in September is the high chance of spotting dolphins and whales. We were thrilled by the opportunity, especially since September is the last month to see humpback whales before they head back to cooler waters.
This month is also prime time for seeing the lively Galapagos penguins. It’s the best time to catch a glimpse of these charming birds while snorkeling—many people report sightings underwater in September, especially around Bartolome. The swimming conditions this month seem perfect for the penguins, making them more active and easier to spot, which added an extra thrill to our snorkeling adventures.
Other wildlife species that you may spot in Galapagos during September are:
- Giant tortoises
- Sea lions
- Galapagos fur seals
- Boobies
- Waved albatross
- Frigate birds
- Other sea bird species
In September, the Galapagos Islands are bustling with life, with creatures both big and small on the move. One of the most fascinating sights for us was watching the giant tortoises on Santa Cruz make their slow journey back from the shore to the lush mountains of the island.
The drama of the animal world unfolds as male sea lions fiercely guard their harems, fur seals begin to breed, and female sea lions give birth. It’s a time of intense activity and transition, and we felt lucky to witness these natural rhythms up close. September truly brings the wild heart of the Galapagos to life.
Galapagos in September: Tourist Crowds
In September, the Galapagos Islands settle into their low season, bringing a quieter and more relaxed vibe. My wife and I appreciated how much less crowded it felt, which made for a more peaceful experience, allowing us to truly take in the surroundings.
One of the perks of visiting in September is the savings—you’ll find lower rates on flights, accommodations, and excursions, both on land and at sea. With the islands quieter, we could enjoy the vibrant wildlife without the usual crowds, which made each encounter feel more intimate.
Daily temperatures range from 67 to 70 °F, with the ocean holding steady around 70 °F. It’s also one of the driest months, with low humidity and minimal rain. For the evenings and any cruises, warmer clothes are a good idea, as it can get a bit chilly, adding a cozy touch to the day’s adventures.
Galapagos in September: Weather
September brings cool, dry weather to the Galapagos, with skies often overcast or misty, creating a more moderate climate than the tropical months. My wife and I found the cooler temperatures refreshing, making it comfortable for exploring without the intense sun bearing down.
One important tip: don’t forget good sun protection, even under cloudy skies. Being close to the equator means it’s still easy to get a sunburn, and the clouds can be deceiving. We were careful to reapply sunscreen regularly, which made a big difference. With only the occasional light drizzle in the highlands and no heavy rain, September offered ideal conditions for outdoor activities without interruption.
Galapagos in September: Activities
Even though the sea is a bit cooler in September, snorkeling, diving, and swimming are still fantastic options in the Galapagos. My wife and I made sure to bring our own wetsuits, just in case the water felt too chilly, and it definitely helped us stay comfortable. You can rent wetsuits before boat trips, but we found it useful to have our own on hand.
In September, it’s wise to steer clear of mature male sea lions while in the water, as they can be more aggressive and vocal during mating season. Beyond the incredible wildlife encounters, September is also an ideal month for walking, trekking, and exploring other islands in the archipelago. The activities are much the same as during the rest of the year, but the cooler weather made our adventures even more enjoyable.
