Why Faxaflói Bay Concentrates So Many Cetaceans
The regular presence of cetaceans in Faxaflói Bay is no accident. It results from precise oceanographic conditions that make this area one of the most productive in the North Atlantic.
Upwelling and Nutrient Richness
The bay receives inflows of cold, nutrient-rich water from the Icelandic continental shelf. These cold-water upwellings, combined with the prolonged sunlight of the boreal summer, trigger intense phytoplankton blooms. Phytoplankton feeds zooplankton, which in turn feeds forage fish and large filter feeders. This is the base of the entire local marine food chain.
Capelin, Herring and Krill: The Prey That Attract Whales
Whales follow their prey. In Faxaflói, concentrations of capelin (Mallotus villosus), Atlantic herring (Clupea harengus) and krill (Meganyctiphanes norvegica) vary by season and year. Capelin, in particular, is a key prey for the minke whale (Balaenoptera acutorostrata).
Geographical Position of Reykjavik
Whale-watching boats depart from the Old Harbour and reach Faxaflói Bay off the capital. Few capitals offer such direct access to waters frequented by cetaceans.
Species to Identify at Sea: Field Criteria
Identifying a species from a boat deck requires practice. Here are the essential visual and behavioural criteria for species regularly encountered in Faxaflói.
Minke Whale (Balaenoptera acutorostrata): Discreet Blow and Falcate Dorsal Fin
The minke whale measures between 7 and 10 m. Its blow is barely visible, often absent to the naked eye in calm weather. The falcate dorsal fin (curved backward) appears simultaneously with the back during surfacing, a reliable diagnostic criterion. A characteristic white band on the pectoral fins is visible at close range. It never raises its tail fluke when diving.
Humpback Whale (Megaptera novaeangliae): Lobtailing, Breaching and Unique Tail Pattern
The humpback whale can reach 14 to 16 m and is recognised by several spectacular behaviours: breaching (leaping out of the water), lobtailing (slapping the tail fluke on the surface) and spy-hopping (head held vertically out of the water). When diving it systematically raises its tail fluke, whose ventral pigmentation pattern is unique to each individual, enabling photo-ID and contribution to databases such as Happywhale. Its blow is columnar and visible up to 3 km in calm weather.
White-Beaked Dolphin (Lagenorhynchus albirostris): Surface Behaviours
The white-beaked dolphin (Lagenorhynchus albirostris) is the most frequent dolphin in Faxaflói. It is recognised by its short white rostrum, light grey flanks and energetic behaviours: bowriding (swimming in the boat's wake), frequent jumps. Groups can number several dozen individuals. The bottlenose dolphin (Tursiops truncatus) is rarer in these cold waters.
Harbour Porpoise (Phocoena phocoena): Small Size, Discretion and Triangular Dorsal Fin
The harbour porpoise is often underestimated by novice observers. It measures only 1.4 to 1.9 m, its dorsal fin is triangular and low, and it generally avoids boats. Its blow is almost inaudible. It is spotted mainly in calm weather by scanning the surface at close range. Non-migratory, like the white-beaked dolphin, it remains in Faxaflói year-round.
Occasional Species: Fin Whale, Orca, Pilot Whale
The fin whale (Balaenoptera physalus) may cross the bay during migrations. The orca (Orcinus orca) is reported irregularly, often linked to herring schools. The long-finned pilot whale (Globicephala melas) is observed occasionally, especially in autumn. These encounters remain unpredictable and should not be presented as guaranteed.
When to Go: Seasonal Variations and Sea Conditions
Reykjavik operators offer trips year-round, but species and conditions change by month. Elding's classic trip, for example, runs all year.
April to October: High Season
Migratory whales, minke whales and humpback whales, are most numerous in spring and summer, the feeding period (Icelandair). Days are very long, with more than 20 hours of daylight in June. Elding's RIB trip (2 hours, maximum 12 people) operates only April to October. This is also the busiest period: advance booking is advised.
November to March: Winter Trips
Most humpback and minke whales leave Icelandic waters in winter, yet a few remain in Faxaflói Bay (Special Tours). In January 2019 that operator saw humpback whales on 90 % of trips: an exception, not a rule. Non-migratory white-beaked dolphins and harbour porpoises stay year-round. Weather is more unstable, cancellations more frequent, and days are very short, about 4 hours of daylight in December. Some operators also offer "northern lights" cruises in winter.
Weather and Sea State
Faxaflói Bay is exposed to Atlantic depressions, and trips are cancelled when the sea is too rough, more often in winter. Those prone to seasickness should plan ahead (see equipment below).
Which Time Slot to Choose
Operators offer several departures daily in high season, but schedules change seasonally: check the operator's calendar when booking.
Choosing an Ethical Operator: Code of Conduct and Questions to Ask
Choosing an operator matters. Practices vary, and concrete criteria help distinguish serious operators.
No Law, a Code of Conduct
Iceland has no whale-watching regulations: this is stated by Elding, a Reykjavik operator and founding member of IceWhale. The Icelandic operators' association therefore established a code of conduct for responsible whale watching in 2015 that serves as the profession's reference. It is not a law and cannot be enforced (Friends of Moby Dick, IceWhale member).
What the Code of Conduct Says
According to texts published by Elding and Friends of Moby Dick: animals are approached from 300 m while reducing speed (5 to 6 knots), vessels do not deliberately approach closer than 50 m, the engine is stopped if an animal approaches, and cetaceans are not touched, fed or swum with. Elding additionally limits contact to 20 to 30 minutes maximum with the same animal or group. These are operator commitments, not legal obligations: ask your operator if it belongs to IceWhale.
Concrete Questions to Ask Before Booking
Before booking it is useful to ask: what is the maximum number of passengers on board? Is a trained naturalist present (distinct from the captain)? Does the operator participate in photo-ID or citizen-science programmes? What is the policy if no cetaceans are seen? A serious operator answers these questions directly.
The Icelandic Paradox: Whale Watching and Whaling in the Same Country
This is a subject commercial sites often avoid: Iceland has not abolished commercial whaling. Some Reykjavik operators publicly state their opposition (Elding publishes an "Anti-whaling" page). This is an ethical criterion to verify explicitly: choosing an operator that clearly states its position is a concrete way to direct your money.
Typical Trip from Reykjavik's Old Harbour
Here is what field observers report as the usual sequence of a trip from the Old Harbour (Gamla höfnin), without embellishment.
Boarding and Briefing
Arrive at the operator's desk before the departure time on your ticket. A safety briefing is mandatory. Serious operators add a naturalist briefing: potentially observable species, behaviours to watch, instructions not to disturb the animals. Thermal suits or deck jackets are supplied or available for rent.
At Sea: Approach Protocol and Lookout Role
A lookout (often the naturalist or a trained crew member) scans the horizon from the bow or upper deck. When a blow is spotted the captain reduces speed and approaches laterally, never directly toward the animal. The engine may be cut to allow passive listening. Passengers are asked to remain calm and avoid sudden movements on deck.
Duration, Comfort and On-Board Equipment
Elding's classic trip lasts 2.5 to 3.5 hours on a large boat with a heated enclosed deck. Elding also offers, April to October, a RIB trip of 2 hours for a maximum of 12 people, closer to the water and more exposed to spray. Binoculars are useful; some operators provide them.
What to Do If No Cetaceans Are Seen
Trips without sightings occur even in high season. Several operators then offer a free repeat trip: on Guide to Iceland, for example, the ticket allows participation in another departure at no extra cost. This guarantee should be checked before booking. Absence of cetaceans is not a failure: sea conditions, light and seabird observation (puffins, gannets, skuas) constitute a valid field experience in themselves.
Logistics and Budget: Access, Fares and What to Bring
Access to the Old Harbour from Reykjavik Centre
The Old Harbour is within walking distance of the city centre, and several operators have offices directly on the quays. No car rental is needed to reach departures.
Published Prices from a Reference Operator
Here are the fares displayed by Elding, one of Reykjavik's main operators. They apply first to Elding and change: check the current price before booking. The classic 2.5 to 3.5 hour trip costs 14 500 ISK per adult (about 100 €), 7 250 ISK for children 7 to 15 years, and is free for under 7s. The premium RIB trip (2 hours, maximum 12 people, April to October) costs 24 900 ISK. Hotel transfer adds 3 750 ISK per adult. Other operators have their own rates and conditions: compare before booking.
Essential Equipment
Even in summer it is cool at sea, especially with wind. Thermal layers under waterproof clothing are essential. 8x42 or 10x42 binoculars significantly improve the experience, especially for spotting blows at distance. For photo-ID, a telephoto lens from 300 mm is useful. If prone to seasickness, consult a pharmacist before departure: preventive medication is taken before boarding.
Puffins and Northern Lights: Combining Trips
From the same harbour Elding also offers puffin trips of about 1 hour, 20 April to 20 August, at 8 300 ISK for the classic trip, plus "northern lights" cruises in winter. If staying several days in Reykjavik you can combine a whale trip with one of these, depending on season.
Reykjavik versus Húsavík
Húsavík, in the north, is Iceland's other major whale-watching port: Reykjavik boats cover Faxaflói Bay, Húsavík boats cover Skjálfandi Bay (Guide to Iceland). Reykjavik is more accessible for a short stay centred on the capital without crossing the country. For a dedicated cetacean-watching trip, see our Húsavík guide.
Conservation: Population Status and Issues for Iceland
IUCN Status of Species Observed in Faxaflói
The minke whale is classified "Least Concern" (LC) globally by the IUCN (IUCN, 2018), yet regional subpopulations are monitored closely. The humpback whale has also been LC since 2008, after notable recovery following the end of international commercial whaling (IUCN, 2018). The harbour porpoise is LC globally, but some European subpopulations are under pressure (IUCN, 2019). The white-beaked dolphin is LC (IUCN, 2019).
Commercial Whaling of Minke Whales in Iceland
Iceland has not abandoned commercial whaling. According to the Whale and Dolphin Conservation (WDC), it resumed in June 2026 after two years without any whales being killed. The 2026 quota is set at 150 fin whales, plus 168 minke whales that may be hunted, even though no minke has been killed in recent years. The WDC and other NGOs track these figures annually.
Contribution of Whale Watching to Protection
Several Reykjavik operators publicly oppose whaling. Choosing a whale-watching trip rather than a restaurant serving whale meat is the most direct way to direct your money.
How to Report a Sighting: Happywhale and Photo-ID
Photos of tail flukes of humpback whales can be submitted to the Happywhale platform, which compares them against a global database to identify individuals and reconstruct their movements. This is a concrete contribution to citizen science, accessible to any observer with a camera. Some Reykjavik operators collaborate directly with local photo-ID programmes and collect data from their passengers. I recommend asking the operator if it participates in such a programme before booking.
FAQ
What is the best time to see whales in Reykjavik?
April to October offers the best probabilities: migratory whales are more numerous in spring and summer, and days are very long. Trips continue in winter: white-beaked dolphins and harbour porpoises remain year-round, and a few humpback and minke whales may stay in the bay, but sea conditions are more challenging.
Which species is seen most often in Faxaflói Bay?
The minke whale (Balaenoptera acutorostrata) is the whale most frequently seen in Iceland and can often be observed year-round (Icelandair). The humpback whale (Megaptera novaeangliae) is more spectacular but less consistent: it is mainly present in spring and summer, linked to prey concentrations. White-beaked dolphins and harbour porpoises remain in the bay year-round.
How much does a whale-watching trip cost in Reykjavik?
At Elding, one of Reykjavik's main operators, the classic 2.5 to 3.5 hour trip costs 14 500 ISK per adult (about 100 €), half price for children 7 to 15 years, and the premium RIB trip 24 900 ISK. Other operators have their own rates: check the current price before booking. Several offer a free repeat trip if no cetaceans are seen; verify before paying.
Is it better to depart from Reykjavik or Húsavík to see whales?
Húsavík, in northern Iceland, is the country's other major whale-watching port on Skjálfandi Bay. Reykjavik is more accessible for a short stay without crossing the country, and trips run year-round. The choice depends on available time, season and the importance placed on logistics.
Are trips cancelled in bad weather?
Yes. Operators cancel trips when sea conditions exceed safety thresholds. In case of cancellation a full refund or rescheduling is usually offered. Check each operator's cancellation policy before booking, especially in autumn and winter.
How do you distinguish a minke whale from a humpback whale at sea?
The minke whale measures 7 to 10 m, its blow is barely visible and its falcate dorsal fin appears simultaneously with the back; it never raises its tail fluke when diving. The humpback whale (up to 16 m) systematically raises its tail fluke when diving, produces a columnar blow visible from afar and often shows acrobatic behaviours such as breaching.
Does Iceland still practice whaling?
Yes. According to the WDC, commercial whaling resumed in June 2026 after two years without any whales being killed. The 2026 quota is 150 fin whales and 168 minke whales, even though no minke has been killed in recent years. Some whale-watching operators in Reykjavik publicly oppose the practice; this is a criterion to verify when choosing a trip.
Can you contribute to science by joining a whale-watching trip?
Yes. The Happywhale platform allows submission of tail or pectoral fin photos to contribute to individual identification of humpback whales. Some Reykjavik operators collaborate directly with local photo-ID programmes and collect data from their passengers.
Is seasickness a problem in Faxaflói Bay?
Faxaflói Bay is exposed to the North Atlantic and swell can be significant, especially in autumn and winter. A preventive seasickness treatment taken about one hour before boarding is recommended for those prone to it.
What minimum distance must a boat keep from whales in Iceland?
There is no law on whale watching in Iceland: the IceWhale code of conduct, established in 2015, is the reference. According to operators that apply it, animals are approached from 300 m while reducing speed to 5 or 6 knots, and vessels do not deliberately approach closer than 50 m. These are commitments, not legal obligations: ask your operator if it belongs to IceWhale.
