When to go to Lapland

Lapland weather and daylight, month by month

The table uses Rovaniemi, on the Arctic Circle, as the reference point. Temperatures are the average daily low and high at Rovaniemi airport from 1991 to 2020, from the Finnish Meteorological Institute (FMI). Snow is the median depth FMI recorded there on the 15th of the month. Daylight is the time from sunrise to sunset on the 15th, as moisio.fi calculates it with FMI’s definition of sunrise.

Averages hide the cold snaps. The lowest reading at the airport from 1991 to 2020 was −38.1 °C, in January 1999. Another FMI station in Rovaniemi, Apukka, sits lower (106 m against the airport’s 189 m) and recorded −47.5 °C that same month.

The light changes faster than the temperature. At the Arctic Circle the day never shrinks to nothing: FMI says that at its shortest it lasts a couple of hours, depending a little on how it is calculated, and that in midwinter, when the sun barely shows, there are a few hours of twilight around midday. moisio.fi, which follows FMI’s definition, gives 2 hours 15 minutes for 21 December 2026; other calculators give up to half an hour more. In summer it turns the other way: the City of Rovaniemi says the midnight sun is visible on clear nights from 6 June to 7 July.

Why February and March suit most people

February and March give you the whole winter at once, without the deepest midwinter darkness. The median snow depth at the airport is 66 cm in mid-February and 77 cm in mid-March, the deepest of the year. Daylight grows from about 8 hours in mid-February to nearly 12 in mid-March. FMI names February and March among the strongest months for the aurora, alongside September and October. March is also milder than January, with average lows around −9 °C instead of −14 °C.

Two other months are right for a narrower reason. December is for Christmas: see Christmas in Lapland and Santa Claus Village. September is for autumn colours, which Visit Rovaniemi says are usually at their peak in mid or late September, and for the aurora season, which starts in late August.

How to choose your month

Four questions decide it. Each answer costs you something.

How much daylight do you want?

More light means lighter nights. From mid-April to late August the nights are too light for the aurora. In December you get under three hours of sun, and your daytime activities happen in twilight. February and March sit between the two.

Do you want the Northern Lights?

Then come between late August and early April. Visit Rovaniemi says the lights can still appear until around mid-April. FMI’s strongest months are February and March, then September and October. The trade: in September and October there is no snow to rely on, and in February and March the nights are cold. December has the longest nights, but not more aurora activity, and it is the busiest time. Our Northern Lights guide explains how many nights to plan.

Do you need snow?

Two sources answer this differently. The Finnish Meteorological Institute’s station records put the first unbroken snow cover near Rovaniemi around 21 October, and its own definition has winter beginning in mid-October with permanent cover about two weeks later. Visit Rovaniemi tells visitors the first snow melts away fairly quickly and the cover that stays arrives in late November, sometimes only around December. If your trip depends on snow rather than on a forecast, plan on the later date. The median depth at the airport is 28 cm by mid-December and stays above 40 cm from mid-January to mid-April. By 30 April it is down to 27 cm, and by mid-May there is none. The trade is cold: the snow months are the freezing months, though March gives you the deepest snow with milder days than January. Further north the snow lasts longer: FMI’s median at Sodankylä on 30 April is 41 cm.

How much do crowds matter?

December is Rovaniemi’s peak. For winter 2023 to 2024, Visit Rovaniemi estimated 60,000 to 80,000 travellers in December, counting day visitors from other resorts, out of around 300,000 for the whole winter season. It named 23 December as the busiest day at the airport, and said daily visitor numbers at the Santa Claus Main Post Office rise to 6,000. If you come for Christmas, you come with everyone else, so book early.

Finnish schools take their winter holiday in staggered weeks between 22 February and 12 March 2027, and Rovaniemi’s schools are off from 8 to 12 March, so Finnish families are free to travel then too. Rovaniemi’s hotels give the clearest monthly picture. From 2023 to 2025, December and February were the fullest months, with about 95% and 92% of rooms taken on average, and April and May the emptiest, with about 37% and 34% (Statistics Finland). These figures cover hotels only, and Rovaniemi only: Lapland’s ski resorts keep a different calendar.
