The best time to visit Senja for most people is summertime. The long days and warmer weather ensure the best conditions for hiking and camping. The optimal time to visit for the northern lights is in autumn or late winter/early spring. Senja has very similar seasons to its northerly neighbor Tromsø.

Summertime on Senja

The months from June to September are the warmest on the island and suited to hiking, fishing, and camping. You can experience the midnight sun from the middle of May to the end of July, with almost endless days for a month either side of this period.

High temperatures during summer are usually between 10 and 15°C but highs of 20°C are possible. As Senja is a mountainous island by the open ocean, the weather can vary a lot. If you spend a few days on the island there will almost certainly be a rainy day.

As with any trip to Northern Norway, be prepared for any weather and try to build in a few days of flexibility to allow for changing conditions.

Best time to see the northern lights on Senja

From September the days become increasingly shorter and this means the northern lights begin to show themselves. At the end of November the polar night begins and the sun is no longer visible.

The weather is somewhat unpredictable into January. From the middle of the month the sun starts to show itself once again. Conditions for northern lights viewing are very good into April.

In spring Senja is covered in snow, and although hiking is not possible, the ever-increasing daylight ensures the island is a beautiful sight. Temperatures through winter are quite mild considering the northerly location, hovering between 0 and -10°C. The roads are slippery with ice and you should only drive if you have experience on icy roads.

Hopefully this guide to the seasons has helped you decide when to go to Senja. If you have any questions about your trip, just let us know in the comments below.



    Hi, am from Australia. If I visit Senja island, how do I get to the island from Finnsnes Kai ( after taking the Airport Express bus from Bardufoss). Do I take a ferry from FINNSNES or does it have a connecting bridge to travel by bus/car?

    • Espen Oldeman Lund

      Yes, there is a bridge connecting Finnsnes to the Senja Island. We have some more information about transportation to and around Senja at this link.

  2. We are planning to visit Senja in May 2019 (May 19th to be precise). Will we be able to do some simple hiking? Or will the hiking paths be covered with snow? Also will the ferry from brensholmen to boteham be suitable for people who suffer from sea sickness. I realise it is only a 40 mins ride, but just wanted to confirm if the sea is generally rough in that stretch.

    • Espen Oldeman Lund

      It is very hard to know when the snow will be gone as is varies a lot from year to year. But most likely you should be able to do some hike in the lower areas, but expect to see snow in the higher terrain.

      The ferry ride can be bumpy if the weather is bad, but generally, it should be fine.

  3. Hej
    Planerar Senja i mitten av april. Tacksam för turförslag på ski- hytte t hytte. 3 dager med samma begynnelse som sluttpunkt.

    Tack på förhand,

      Hi! We don’t have a lot of info about skiing on Senja right now. But I think a multi-day cabin to cabin round-trip would be difficult without backtracking. I’d recommend checking out for some ski trip suggestions.

    I am from India. Planning to visit Tromso and Senja in October’19 end. Is there any ferry services available to Senja. How would be the October month to travel there.


    • Aaron Beaton

      Hi! There is no car ferry in October, but the boat to Finnsnes will be running. October will be chilly but it’s a nice time to see the northern lights if that’s what you want 🙂


  5. Sheila Newton

    Is February a good time to visit senna to see the northern lights? Which is the very best time to view the lights

    • Aaron Beaton

      Hi Sheila. There is no real best time, but February is a great option, particularly if you want to ensure a snowy experience. There are no guarantees that you will see the lights, as they came and go as they please. It’s about giving yourself the most chance by spending several days in the area and filling your days with other fun activities.


  6. Angie Curiale

    Is their cabins or hotel to stay at to see the Northern Lights. I’m a 70 years old woman and don’t ski anymore. I don’t hike either. But, I was told the best place to see the Northern Lights would be Senja Norway.

  7. Michael Murphy

    Would mid October be a good time to see The Northern Lights?

    • Aaron Beaton

      Hi Michael, yes it would be a good time. There’s no guarantees obviously, so make sure you have at least a few days to spend.


  8. Hello, we would like to visit Sonja mainly to see the northern lights. My question is would the end of September be a good option and are the roads still driveable considering we live in London. Are the campsites still open that time of year.

    Many thanks for you reply

    Mark and Marie London

    • Aaron Beaton

      Hi Mark, yes the northern lights will be visible in late September if they choose to appear. The roads should be fine for you at that time. Campgrounds are open.


  9. Hi we are coming te Senja late September. Does the equinox has Influence on the northenlights?
