Nordhavn After Midnight: Saunas, Smoked Fish and Copenhagen's Endless July Light

At 1:47 a.m. on a Thursday in July, the sky over Nordhavn was the color of a bruised peach. I was sitting on the edge of a floating pontoon at CopenHot, barefoot, steam still rising off my shoulders, watching a woman in a wool hat eat pickled herring straight from a jar. Nobody was in a hurry. Nobody had been in a hurry for hours.

Nordhavn is Copenhagen's newest district in the way that a warehouse you gut and rewire is new — the bones are old port infrastructure, concrete grain silos, and industrial quays, now stacked with angular residential blocks and threaded with cycling paths that run right to the harbor edge. It sits northeast of the city center, about 4.5 kilometers from Nyhavn by bike, and it's still being built. Cranes are part of the skyline. That's not a flaw. It means the neighborhood hasn't calcified into a tourism product yet, and the people you meet at midnight are mostly people who live here.

1. Getting there without overthinking it

Take the M4 metro line to Orientkaj station. It opened in 2024 and cut the trip from Kongens Nytorv to under ten minutes. That's the whole answer.

If you're cycling — and in July you should be — the route along Østbanegade turns into Sundkrogsgade and deposits you right at the harbor basin. Flat the entire way. You will not break a sweat unless you're racing a cargo bike full of toddlers, which you will lose.

2. CopenHot and the case for sweating in public

CopenHot operates floating saunas and hot tubs on the harbor at Refshalevej 325C (their Nordhavn pop-up location varies by season — check their site before you walk). A two-hour sauna session costs around 200 DKK per person. You book online. You show up. You sweat. You jump into 16°C harbor water. You repeat until your brain finally shuts up.

The wood-fired saunas hit roughly 80°C, which is moderate by Finnish standards but aggressive enough that you'll want the cold plunge by minute twelve. In July, the water temperature hovers around 18-20°C, which is almost pleasant. Almost.

I've seen travel guides call the harbor baths at Islands Brygge the quintessential Copenhagen water experience. I disagree. Islands Brygge is a public pool with a view. CopenHot is stranger and better — you're bobbing in a repurposed shipping container while the midnight sky refuses to go dark. The weirdness is the point.

3. Smoked fish at Nordhavn Røgeri

Nordhavn Røgeri operates out of what looks like a shed that someone pressure-washed and gave a liquor license. It sits on Sundkaj, close to the water. The smoked mackerel is dense and tastes like the sea filtered through applewood. A plate of it with rye bread and remoulade runs about 95 DKK.

They also do smoked salmon, but every place in Copenhagen does smoked salmon. The mackerel is why you're here.

Hours are irregular — generally 11:00 to 20:00, closed Mondays, but they sometimes extend on warm July evenings when foot traffic picks up. Don't plan your day around it without checking Instagram for same-day updates.

4. The silo that became a building that became a viewpoint

The Silo, at Helsinkigade 29, is a converted grain silo turned luxury apartments with a public restaurant on the top floors. The architecture firm COBE kept the original concrete frame and wrapped it in galvanized steel balconies that tilt outward at precise angles. From the 17th floor, you can see the Øresund Bridge, Malmö, and the wind turbines at Middelgrunden — a 40-megawatt offshore wind farm sitting 3.5 kilometers east in the strait.

The restaurant, Silo, serves a tasting menu that starts around 1,200 DKK. The food is fine. The view does most of the work. If you want the panorama without the bill, the common areas on the lower floors offer partial sightlines, but this is one case where the money buys something you can't fake.

5. Skip Reffen if you've been before

I know. Reffen (the Copenhagen street food market on Refshalevej 167A) gets recommended in every guide. And for first-timers it's a solid introduction — dozens of stalls, harbor views, cheap-ish beer. But the food quality has become uneven. Last time I was there in July 2023, half the stalls were serving the same pulled-pork-on-a-brioche template, and the lines for the good ones (the duck fat fries place, the Oaxacan taco stand) were 25 minutes deep.

If you've already done Reffen once, spend that time in Nordhavn proper instead. The ratio of interesting food to standing-in-line is better.

6. Where to stay in Nordhavn (and why you'd want to)

Hotel options in Nordhavn itself are limited, which is part of the appeal — this isn't a hotel district. The closest well-located option is the STAY Copenhagen on Islands Brygge or properties near Østerport station, which puts you a twelve-minute bike ride from the harbor.

The argument for staying nearby rather than in the Indre By is simple: July light. If you're out until 2 a.m. walking the quays and the sky is still glowing, you want a short ride home, not a 30-minute metro-to-bus transfer. The neighborhood is dead quiet by 3 a.m. — no bar noise, no stag parties, just concrete and water and that pale amber light that won't commit to being night.

A few apartment rentals have appeared in the newer residential blocks along Århusgade. Expect to pay 1,200-1,800 DKK per night for a one-bedroom with a harbor view. The build quality is good. The furniture is always Hay or Muuto. You will feel like you're inside a catalog, which in Denmark is not an insult.

7. Århusgade after dark

Århusgade is the main commercial street in Nordhavn, and it's about 400 meters long. A bakery, a wine bar, a couple of restaurants, a grocery store. No souvenir magnets.

Hart Bageri has an outpost here. A cardamom bun costs 38 DKK and is worth the specificity of seeking it out — the lamination is tight, the cardamom is ground fresh, and they don't oversweeten it the way most Nordic bakeries do. Open from 07:00, usually sold out of the best stuff by 10:30.

The wine bar Rudo, on the same stretch, pours natural wines by the glass starting around 85 DKK. The space is small — maybe fourteen seats — and the playlist leans toward late-'70s Japanese ambient, which either appeals to you or doesn't. It appeals to me.

8. Swimming in the harbor at midnight because the sun won't set

Nordhavn's harbor bath — Nordhavn Havnebadet — opened in recent years at Sandkaj. Free. Open 24 hours in summer. The water quality is tested regularly by the municipality and is clean enough that the city stakes its reputation on it.

In July, civil twilight in Copenhagen lasts from roughly 22:30 to 03:45. The sun dips to about 7 degrees below the horizon at its lowest, which means full darkness never arrives. Swimming at midnight feels like swimming at dusk — the light is low and golden-gray, the water is calm because the wind usually drops after 21:00, and you share the pool with maybe three other people.

Bring a towel. There are no rental facilities. The changing rooms are basic — open-air wooden cubicles, no lockers. Leave valuables at your accommodation.

I made the mistake of leaving my phone on the dock last July. Nobody took it. This is Copenhagen. But still — bring a dry bag.

9. The 3 a.m. walk back

After midnight, when the saunas close and the wine bar dims its lights, walk the full loop around the Redmolen peninsula. It takes about twenty minutes. The path is paved and lit, though "lit" is generous — a few bollard lights and whatever the sky is doing.

You'll pass the UN City building, which looks like a star from above but from ground level just reads as aggressive glass. You'll pass docked sailboats. You'll pass apartment buildings where every third window is open because nobody in Denmark owns air conditioning and July 2023 hit 31°C.

The loop ends back at Orientkaj station. The last M4 metro toward the city center runs at 00:30 on weeknights, but on Friday and Saturday nights, service continues through to morning. If you miss it on a Tuesday, the walk to Nordhavn S-tog station is 1.2 kilometers south, and the first train runs at 05:15.

Or just sit on the quay. The light will be back before you know it.
