September marks the start of the final chapter of our Arctic expedition cruise season, and it brings a wealth of new possibilities. As the Arctic summer fades and the colors of autumn bloom, Greenland takes center stage. Thinning sea ice, vivid autumnal tundra, and abundant wildlife preparing for the long winter make September a superb time to explore lesser-visited locations, offering a chance to experience the fleeting Arctic autumn - a period of superb light conditions, the first tendrils of winter, and the rhythm of change throughout the polar world.
Many of our expedition cruise itineraries towards the end of August start in Longyearbyen, Svalbard, and end in Greenland. From September onwards, East and South East Greenland is the focus, with trips exploring the dramatic landscapes of this wild coastline. In September, our ice-strengthened expedition vessels, m/v Hondius, m/v Ortelius, m/v Plancius, and s/v Rembrandt van Rijn, take guests across the Greenland Sea, leaving Svalbard behind and entering an ancient world. Rugged and nimble, these expedition vessels are designed for close encounters with ice, remote landings, and in-depth Arctic exploration without the crowds or constraints of large cruise ships.

What to expect on an expedition cruise with us
While with us, you'll be guided by a passionate team of experts with varied interests and experience, ranging from marine biologists, glaciologists, and historians to wildlife photographers, geologists, and conservation experts. Prepare for a more immersive, in-depth knowledge on land and at sea as our team and your fellow guests bring every landscape and encounter to life through enthusiasm and a thirst to explore and discover.
Our small-scale approach means more time ashore and more Zodiac cruises than with larger operators. This becomes especially beneficial in September, as our long hike trips in Greenland's Scoresby Sund explore the farthest reaches of this spectacular polar world, and the iceberg-laden shores of Greenland present superb opportunities to explore by Zodiac, kayak, and on foot. We also offer cruises to Greenland that do not focus on long hikes, so there's something for everyone in this remarkable part of the Arctic.

Arctic expedition cruise with us in September
September is a month of change in the Arctic. The endless daylight of summer begins to give way to the first hints of twilight, and later in the month, dark skies full of the wonders of the Northern Lights. The soft, golden light in the morning and evening bathes the ice and tundra in warm hues, creating outstanding conditions for photographers and nature lovers alike.
As the weather becomes more changeable, the glorious late-season sunshine provides excellent conditions for hiking in Greenland. Zodiac cruises often take in large glacier fronts or encounter immense icebergs, while sea-based activities, including kayaking, allow guests to share the seas with whales and seals awaiting the coming of winter. On select trips, you may also get the chance to snorkel and dive in the frigid seas.
Scoresby Sund
One of the biggest draws of our Greenland trips is Scoresby Sund. Located in East Greenland, the Scoresby Sund fjord system—the largest and one of the most spectacular on Earth— has to be seen to be believed. Its towering icebergs and mountain-flanked fjords are breathtaking, with glaciers spilling from the tops of towering peaks. In Øfjord, the spiraling peak of Grundtvigskirken juts majestically over huge icebergs, which, against the sheer scale of the landscape, appear minuscule in comparison.
In Scoresby Sund, our long hikes activity is at its best. The expansive tundra and rugged terrain offer superb opportunities to explore this ancient world. Long hikes typically last upwards of 5 hours, spending entire days away from the ship and traversing terrain where few have stepped before.

Colors of the Tundra
At this time of year, the tundra is especially beautiful, with plants such as dwarf willow, birch, reindeer lichen, cottongrass, and various mosses carpeting the landscape in vivid color. Underfoot, dry leaves and branches crunch and crackle while springy moss flourishes amidst pools of water and icy recesses in the rock.
This makes September particularly interesting for photographers seeking to capture the contrasting light conditions and the superbly vivid colors of the Arctic flora.
The Northern Lights
As dark skies return to the Arctic, the shimmering, otherworldly bands of the Northern Lights, or Aurora Borealis can be seen in the skies above Svalbard and Greenland. As our expedition cruises to Greenland take place more frequently, these are perfect trips for those seeking to experience the wonders of the Northern Lights for themselves.
The dark unspoilt skies of Greenland provide superb conditions for viewing the aurora, making your polar adventure a constant experience, and one that doesn't end at sunset. While on an expedition cruise in Greenland, announcements will be made when aurora occur, giving you plenty of time to throw on a coat and grab your camera before heading out on deck.

What's the weather like in September in the Arctic?
September temperatures in the Arctic range between -2°C and 8°C (28°F to 46°F). Days are growing shorter, but they are still long enough for full exploration. The weather tends to be relatively calm, though more changeable than in high summer. Misty mornings and crisp air are common, and the tundra begins to shift into autumn colors - burnt orange, deep red, and golden yellow.
The retreat of the sea ice opens up more routes, especially along Greenland's rugged coast. These are voyages not possible earlier in the season, making September ideal for those seeking to explore the eastern shores of Greenland. Despite the lateness of the season, ice remains. You'll encounter towering icebergs both along the coast of Greenland and in the many fjords and bays that penetrate toward its glaciated interior.

What should I pack for an Arctic expedition cruise in September?
In September, you can feel the first hints of winter in the air. It is essential to note that the weather can change rapidly in September, although it is generally fairly settled. In particular, wind chill can make temperatures feel much colder, especially at night.
Base layers are key for an expedition cruise to the Arctic in September. Thermal underwear is a good start. Good mid-layers, such as sweaters and down jackets, can help keep you warm while also being easy to remove. Consider bringing a small backpack for when you go ashore; this allows you to layer and remove items as needed.
For outer layers, both waterproofness and a degree of windproofness are essential qualities. Whether it snows and rains or not, you'll need waterproof trousers and a jacket for Zodiac operations. While generally, you will enter and exit Zodiacs without entering the water, spray and changing conditions can mean you may get splashed. Some landings also require you to step into the water – so bear this in mind!

Don't forget warm socks, gloves, and a hat! Bring UV protection as the sun can be surprisingly strong. Sunglasses are handy, especially against the glare of snow and ice. Beyond clothing, consider bringing binoculars to spot wildlife and a camera to capture memories that will last a lifetime.
With us, you will be provided rubber boots and lifejackets for your expedition cruise, but be sure to bring sturdy, comfortable shoes for your time onboard.
What wildlife can I see in the Arctic in September?
Despite the encroaching winter, September is still rich in wildlife. In Svalbard, most seabirds have left, returning south ahead of the colder weather. Polar bears remain, especially in the sea ice, as are walruses, seals, and some species of whale. On shore, the Arctic fox and Svalbard reindeer work to bulk up ahead of the darkness of winter, while ptarmigan, now resplendent in their winter coats, are easy to spot in the tundra.
In Greenland, some unique species await! The magnificent musk oxen roam the vast tundra of Greenland. These ancient-looking animals are only found on the North American continent and Greenland, and on a long hike, you stand a good chance of spotting small family groups. You can also see the Arctic hare in Greenland. In September, their white coats make them easily visible among the vivid tundra. Arctic foxes are also found here, as are polar bears, who await the coming winter and the ice packed with marine life.

Most bird species will have left the shores of Greenland by mid-September, although you'll encounter seabirds and some late stragglers. Of note is the ptarmigan, the only bird to remain in Greenland over winter. Much like in Svalbard, the white winter coat of the ptarmigan makes them easy to spot.
Seals and whales can also be found in the seas of Greenland, although in fewer numbers than earlier in the season. For the truly lucky, an encounter with the almost mythical narwhal is possible, although these elusive animals are rarely spotted.
What makes the Arctic in September so special?
September is a transitional month in the Arctic, and that's precisely what makes it magical. It's a rare time to witness autumnal changes in the polar world. Golden light and lengthening shadows create dramatic photography conditions, ideal for both landscape photography and wildlife encounters. Fjords are full of icebergs with calving glaciers, and the vivid colors of autumn make each direction a visual treat.
Fewer ships also operate later in the season, making a visit to Scoresby Sund truly feel like you are at the edges of the world, far away from the lights of civilization. The Arctic is quieter, wilder, and even more beautiful in September.
