    When is the best time to see the northern lights in Finland?

    The aurora season, the role of darkness and clouds, and when to look up.

    Answered at: Checked at:

    Short answer

    The best time is from September to March, when nights in Lapland are long and dark. Auroras happen in summer too, but the bright nights of the midnight sun hide them. Within the season, what matters most is a dark, cloudless sky. In northern Lapland auroras are seen on most clear, dark nights.

    Weather & Seasons

    Why

    1. Visit Finland names September to March as the best northern lights season in Lapland.
    2. The Finnish Meteorological Institute says three nights out of four have auroras in northern Lapland when the sky is clear enough.
    3. FMI notes that the frequency of large aurora displays follows the 11-year sunspot cycle.

    Details

    Auroras are often strongest a couple of hours either side of midnight, but they can appear any time it is dark. Moonlight and city lights make faint auroras harder to see.

    Tip

    Stay several nights rather than one. If one night is cloudy, the next may be clear.

    What may differ

    Autumn has the bonus of unfrozen lakes that reflect the lights, while winter brings snow and colder, often clearer nights.

    Common misconception

    You can only see the northern lights in the coldest weather.

    What actually happens

    Temperature does not cause auroras. Darkness and a clear sky decide whether you see them.
