Float on your back in a frozen lake under the Arctic sky as the northern lights ripple overhead. Here's what aurora floating in Pyhätunturi feels like, when to come, and how to prepare.
Imagine lying on your back in complete silence, weightless, cradled by dark Arctic water while curtains of green and violet light pulse across the sky directly above you. No windshield, no window, no roof. Just open sky, open water, and the aurora borealis performing at arm's length.
This is aurora floating: one of the most singular experiences in Finnish Lapland, and one that almost nobody outside Pyhätunturi knows exists.
What Is Aurora Floating?
Aurora floating is ice floating done at night, during aurora season. You wear a thermal dry suit that covers everything except your face, step into an opening cut through the frozen lake, lean back, and float. The buoyancy is effortless. The suit keeps you completely dry and warm. And above you, the sky is entirely unobstructed.
The critical difference from daytime floating is what you're looking at. During the day, you see the fell silhouette and the pale Arctic sky. At night, from October through March, you may be looking directly into the aurora oval: the band of geomagnetic activity that circles the Arctic and concentrates its light directly over Finnish Lapland.
When the aurora appears while you're in the water, there is no experience quite like it anywhere on earth.
Why Floating Beats Every Other Aurora Viewing Method
Most people chase the northern lights on foot or from a snowmobile, craning their necks upward. Others watch from cabin windows or glass igloos. Aurora floating is different in one fundamental way: you're already looking straight up.
Floating on your back, your entire field of vision is sky. No horizon to look past, no need to tilt your head. When the aurora moves — and a strong display moves fast, with ribbons and curtains that shift across the sky in seconds — you see all of it, simultaneously, without turning.
The lake also silences everything. You hear your own breathing and the faint sounds of water against ice. No engine noise, no group chatter, no shuffling feet. You are completely still, completely quiet, and the lights are directly above you.
Guests who have done every kind of aurora tour consistently tell us this is the one they remember.
The Experience, Step by Step
Your evening begins at our base near Pyhätunturi, where the guide fits you into a dry suit. The suits are loose and warm, and most people stop noticing they're wearing one within minutes. Over your own base layers, the suit traps heat effectively even as you're in near-freezing water.
We walk together to the lake, which sits in an opening in the forest. The sky above the lake is clear of trees: a full, open window to the north. The guide has checked the aurora forecast and conditions beforehand, and the timing of your float is planned around the period of maximum aurora likelihood.
At the ice edge, the guide demonstrates the entry. You sit, swing your legs into the water, lean back, and let the suit do its work. Within a second or two, you're floating. The cold water presses lightly against your face. The rest of you stays warm.
Then you look up.
On a clear night in Pyhätunturi, the Milky Way is visible with the naked eye — something most people from cities have never seen. Even before the aurora arrives, the star field is extraordinary. Lapland sits at 67°N, well above the Arctic Circle, and the absence of light pollution here is profound. On a new-moon night, the darkness is total except for what the sky produces.
When the aurora appears, it typically begins as a pale arc across the northern sky: a faint green glow that you might mistake for a cloud until it starts to move. Then the structure begins to shift. Vertical rays form along the arc. The green brightens. On active nights, the arc breaks into distinct curtains that ripple from left to right, purple and pink bleeding into the green at the edges. The most intense displays — Kp 4 and above — can fill the entire sky, with rays converging directly overhead in what aurora chasers call the corona effect.
When that happens while you're floating, it feels as though the lights are rising from the water around you.
2026: Catching the Solar Maximum
If you've been planning an aurora trip, 2026 is an exceptional year to do it. We are currently at or near the peak of Solar Cycle 25, a period of maximum solar activity that drives the strongest geomagnetic storms. More solar activity means more frequent auroras, stronger displays, and lights visible at lower latitudes than usual.
Professional aurora forecasters have described the 2024–2026 window as the best opportunity in roughly a decade. The cycle will begin declining from 2027 onwards. For aurora floating specifically, stronger solar activity means more evenings with visible displays and a greater chance that your float coincides with an active sky.
What Determines Whether You'll See the Aurora
Three factors control aurora visibility: solar activity, clear skies, and darkness. In Pyhätunturi during aurora season, two of those three are reliably in your favour.
- Solar activity in 2025–2026 is at cycle peak. The Finnish Meteorological Institute and apps like My Aurora Forecast provide 27-day outlooks and real-time Kp index updates. Our guides monitor these daily.
- Darkness from late September through March is guaranteed. The aurora season in Lapland runs September to March, with total darkness arriving by early October and lasting through February.
- Clear skies are the variable you can't control. Cloud cover is the aurora hunter's only real enemy. In Pyhätunturi, we plan aurora floating sessions for evenings when the forecast shows clear or partially clear conditions, and we have flexibility to adjust timing within your stay when possible.
Staying three or more nights dramatically improves your odds. Multiple evenings create multiple opportunities, and a clear night in Pyhätunturi during active aurora conditions almost always delivers a display of some kind.
When to Come for Aurora Floating
The aurora floating season at Outdoor Artisans runs October through March. Each month has its own character:
- October: Autumn equinox creates a spike in geomagnetic activity. The snowpack is just arriving, the landscape is transitional, and the nights are long enough for good viewing. Temperatures are mild by Lapland standards: -5°C to -15°C.
- November & December: Darkness deepens. Polar night (kaamos) arrives in December, when the sun doesn't clear the horizon. The lake is fully frozen and the snow-covered forest creates a magical setting around the float. Aurora activity is strong; cloud cover is more frequent.
- January & February: Peak aurora season. Cold, crisp nights (-15°C to -30°C) produce the clearest skies of the year. Strong geomagnetic storms are most frequent. The dry suit handles the temperature difference effortlessly, but dress warmly in your base layers underneath.
- March: Light returns rapidly. You can combine aurora floating (evening) with full days of winter activity. Snow conditions remain excellent. One of our most popular months because guests can enjoy both a rich daytime programme and evening aurora sessions.
What to Wear Under the Suit
The dry suit provides all the waterproofing and significant insulation. What you wear underneath determines your comfort level. Our recommendations:
- Merino wool base layers (top and bottom) against the skin. Merino insulates even when damp and won't feel cold against your body.
- A mid-layer fleece or down jacket over the base. The suit goes over both.
- Warm socks: Two pairs of wool socks keep feet comfortable despite the cold water surrounding them.
- Avoid bulky outer layers — they go under the suit and become uncomfortable. Warmth comes from wool, not from thickness.
Your face is the one part exposed to the air. At -20°C, even still air feels sharp against bare skin. We provide neoprene gloves, and a buff or balaclava over the lower face keeps the cold manageable while still letting you look up without obstruction.
The Sauna Afterwards
Every aurora floating session ends with a traditional Finnish sauna by the lakeside. The contrast between floating in near-zero water and the enveloping warmth of a wood-fired sauna is one of the great physical experiences Finland offers: your body floods with warmth, your muscles release entirely, and the endorphins arrive in a wave.
You'll be handed warm drinks and have time to decompress with your group. On aurora-active evenings, the walk back from the sauna to the cabin has produced some of our best accidental aurora sightings: the sky doing its finest work exactly when nobody expected it.
Combine Aurora Floating with Daytime Adventures
Aurora floating works best as part of a multi-day Pyhätunturi stay. During the days, consider:
- Arctic winter fishing on the same lake system you'll float in after dark. The silence and patience of ice fishing connects you to the lake before you float in it.
- Arctic bushcraft skills — learning fire craft, knife work, and wilderness navigation in the boreal forest creates a full Arctic immersion that makes the evening floating feel like a natural extension of the day.
- Snow surfing for contrast: an active, physical day on the fells before the meditative stillness of the evening float.
The combination of demanding days and luminous evenings is what makes a winter Lapland trip feel genuinely transformative rather than just another tick-box holiday.
