Norway’s seabird calendar is shaped by latitude more than any other variable. From Runde on the Møre coast in the southwest to Hornøya on the Barents Sea coast in the northeast, the country spans nearly 13 degrees of latitude and four distinct ocean systems. Atlantic Puffins begin appearing at Runde in late April while Finnmark’s Steller’s Eiders are still massed in the Varangerfjord. Svalbard’s Little Auk colonies are at full roar in July when the Runde season is already past its midpoint. Getting the timing right — matching the right region to the right month — is the single most important planning decision for a Norwegian seabird trip.
Here is a month-by-month breakdown of what’s open, what’s moving, and what you should book and when.
March: Winter Specialties in Finnmark
March is the prime window for Finnmark’s winter seaduck spectacle. Naturetrek’s Varanger Fjord tour runs in mid-March specifically to catch the peak of Steller’s Eider concentration in the Varangerfjord — the largest gathering of this species in Europe, with several thousand birds present on the fjord and at Ekkerøy. King Eider, Long-tailed Duck, and both Common and Velvet Scoters share the same bays and headlands.
Inland, Rough-legged Buzzard is regular and Gyrfalcon patrols the Varanger Plateau. The Barents Sea coastline holds Glaucous and Iceland Gulls, and Ivory Gull is possible at the harbour fish quays.
At the southern end of the country, Hornøya begins its season in March as the first Atlantic Puffins return to the ledges. Early-season departures often find birds still in their offshore winter plumage, catching the arrival before the colony reaches full density.
Book well in advance: Naturetrek’s Varanger tour is a guided group product with a fixed departure date that fills months ahead.
April: The Season Begins
April sees the colony season proper under way across southern Norway. By mid-April, Atlantic Puffins have returned to Bleiksøya off Andøya in Vesterålen — the operator records 14 April as the typical arrival date for this colony with extraordinary regularity. Bleiksøya Puffin & Seabird Safari begins its departures in May but April visits to the area can include pre-season sightings from the shore.
At Runde in Møre og Romsdal, Puffins are back on the cliff-top slopes by late April. The Runde Bird Island Boat Trip opens for the season in May, but late April is when returning Puffins, Razorbills, and Gannets begin to make the colony photogenic again.
In Finnmark, Hornøya’s boat excursions continue through April with growing colony density. April is also prime time for northbound migrant waders on the Varanger coast — Broad-billed Sandpiper and Red-necked Phalarope follow the snowmelt north.
May: Peak Colony Season Begins
May is when Norway’s seabird season shifts into full swing across all accessible regions simultaneously.
Runde opens its daily boat trip schedule in May, offering morning and evening departures from Runde Harbour. The colony at full early-season density has 100,000–150,000 birds. Gannet, Razorbill, Black Guillemot, Kittiwake, and European Shag are all present alongside the Puffins. May also marks the start of northbound Skua passage over the outer Møre coast — Great, Arctic, and Pomarine Skuas all move through, with occasional Long-tailed Skua earlier in the spring.
Vesterålen is operating from the first week of May. The Bleiksøya colony at this point is at its most accessible — birds are fresh back from the ocean, adults are highly visible, and the long Arctic days allow morning and evening observation on the same trip. Departures run at 13:00 and 15:00 daily.
Røst in Lofoten begins its Seabird Safari season in May. The Day @ Sea Røst Seabird Safari explores the outer island chains of Vedøya, Sandøya, and Trenyken that support approximately 25% of Norway’s entire breeding seabird population — a figure that becomes viscerally real when you are circling the Skomvær Lighthouse on a calm May morning.
Hornøya remains in full operation through May. The colony builds toward its densest May–June window.
At this point in the season, the most common mistake is not booking Røst early enough. The boat carries just seven passengers and operates on request rather than a fixed public schedule — contact Day @ Sea directly well before your intended travel date.
June: Long Days, Full Colonies, Svalbard Opens
June is arguably the best single month for Norwegian seabird birding if you can only choose one. Every colony is at or near peak density, daylight is effectively continuous above the Arctic Circle, and the Svalbard expedition season opens.
Svalbard cruises launch in late June. Birding Ecotours’ Svalbard Mammal & Birding Cruise departs Longyearbyen for an eight-day voyage exploring Spitsbergen’s fjords and bird cliffs. Little Auk is the headline species — the Svalbard archipelago holds several million breeding pairs, and June produces the first sustained access to colonies in the fjords. Brünnich’s Guillemot, Atlantic Puffin, Black Guillemot, Northern Fulmar, Black-legged Kittiwake, and Pink-footed Goose round out the breeding birds list. The ice edge in late June remains productive for Ivory Gull.
Runde, Vesterålen, and Røst are all at their most active in June. The long days allow early-morning light on the colonies, and skua activity peaks in late June as post-breeding dispersal begins. Cory’s Shearwaters — an increasingly regular visitor to Norwegian waters as the species’ range expands northward — have been recorded at Runde in June.
For the deepest Svalbard immersion, Field Guides’ Spitsbergen Archipelago Cruise launches in July but the booking window closes well in advance — this 13-day voyage with groups limited to nine participants typically fills in the preceding autumn.
July: Svalbard at Full Noise
July is the month for Svalbard. The pack ice at its summer minimum exposes the most spectacular seabird spectacles in Europe — tens of thousands of Brünnich’s Guillemots and Kittiwakes massing on the Alkefjellet bird cliff, Little Auks streaming to and from their scree colonies in continuous rivers, and Polar Bears hunting on the ice edge with Ivory Gull attendance.
Field Guides’ Spitsbergen & Svalbard Archipelago Cruise runs a 13-day July circumnavigation of the whole archipelago aboard the m/v Ortelius, reaching the remote northwestern and northern coasts where the biggest concentrations of breeding birds and pack-ice specialists are found. Ross’s Gull is possible at the ice edge in July, and Sabine’s Gull is seen on most trips. Oceanwide Expeditions’ North Spitsbergen Explorer runs 18–19 day voyages that push even closer to the polar ice edge — the Alkefjellet column, one of the most spectacular bird spectacles on the planet, is a regular inclusion.
Back on the mainland, July remains excellent at all colony sites. Sooty Shearwaters begin moving through the Runde area in small numbers by late July — a taste of what August will bring.
August: The Autumn Passage Begins
August brings a change in character. The colony season is still active — Puffins, Guillemots, and Razorbills remain on the cliffs through August at Runde and Vesterålen — but the offshore passage dimension opens up.
Sooty Shearwaters move in significant numbers through the Norwegian Sea in August. From the vantage point of Runde or from the deck of a passage boat, flocks of tens to hundreds of Sooty Shearwaters are a regular August sight. Great Shearwaters, Cory’s Shearwaters, and European Storm-Petrels all increase in late August.
Great Skua post-breeding dispersal peaks in August — tens of thousands transit Norwegian waters, and single-day counts of several hundred are possible from exposed Atlantic headlands. Arctic Skua is similarly abundant. This is the month when a boat trip off the Møre coast or in the outer Minch (if combining with Scottish waters) produces the widest suite of skua species in one outing.
Svalbard cruises continue through late August. The Birding Ecotours voyage is an eight-day product that can be scheduled in July or August — August departures catch the late-summer peak of both breeding birds and the first autumn dispersal along the ice edge.
August is also the last month for Hornøya boat excursions. The Skua Nature season closes at the end of August.
September and Beyond
By September the colony season is effectively over south of the Arctic Circle. Runde and Vesterålen boats stop operating. But autumn passage continues.
Autumn shearwater and skua passage in the North Minch and off the Norwegian outer coast peaks in September. For seabird watchers based in the UK or Ireland, combining a Scottish ferry crossing with a Norwegian trip in August or September — when both are at their autumn passage peak — makes geographic sense.
Hornøya runs no boats after August. The Varanger fjord winter specialist season will restart the following March.

Planning and Booking
Lead times: Svalbard cruises book out 6–12 months in advance. The Field Guides and Oceanwide voyages typically fill by autumn of the preceding year. Røst’s small-boat format (7 passengers) sells out quickly once the season dates are announced. Runde and Vesterålen day trips have more flexibility but peak weekends in June and July fill early.
Weather: Norway’s exposed Atlantic coast is genuinely changeable. Even in summer, the North Minch and outer Møre coast can produce westerly gales that cancel departures. Operators will reschedule where possible, but build a buffer day into any Norwegian birding trip itinerary if your travel connections are fixed.
Midnight sun: Above approximately 67°N, the sun does not set between late May and late July. This is one of the genuine spectacles of Norwegian birding — the ability to watch Puffin colonies in full activity at 2am. Bring an eye mask if you need to sleep; plan your trip knowing you won’t have to.
