Please bear in mind that there is annual fluctuation in weather, and these are mere guidelines.
Winter
Christmas, the Polar Night and snowy spring from December to March
December and January are snowy months shrouded in the darkness of the Polar Night. The sun comes out in February and marks the start of the snowy, light-filled spring. March is often terrific for Northern Lights viewing.
In Rovaniemi, the Official Hometown of Santa Claus, Christmas is a special time, as many flock to the arctic town to meet Santa in person and experience the festive season in magical wintery surroundings.
The winter is a great time for a number of activities both in the snow outside and experiencing local culture inside.
Typical daytime temperatures in the winter:
- December: -20 to -10 degrees Celsius
- January: -30 to -15 degrees Celsius
- February: -20 to -15 degrees Celsius
- March: -15 to -5 degrees Celsius
Spring
The snow melts, the ice breaks and nature is reborn in April and May
April is still considered a snowy month in Rovaniemi and Lapland, but the snow gradually disappears as May approaches. The ice on rivers and lakes starts melting, and big chunks of ice can be seen flowing downstream.
In early April, the last of the Northern Lights displays can be seen. Towards the end of April, nights are too light for the Auroras to be spotted.
In May, northern nature starts getting ready to blossom once again after a harsh winter. At the end of May, nights are white.
In Rovaniemi, winter activities still run in early April, after which it’s time for non-snow stuff.
Typical daytime temperatures in the spring:
- April: 5 to 10 degrees Celsius
- May: 10 to 20 degrees Celsius
Summer
The Midnight Sun and white nights in June and July
The Midnight Sun period officially lasts from early June until early July, but nights are white throughout the summer in Rovaniemi. The summer in Lapland can offer an interesting variety of weather conditions, with a longer warm spell expected in July.
The warmest time of year brings people out in masses, and various events take place in summery Rovaniemi. Prepare to celebrate until the wee hours, as the sun never goes down.
There are plenty of things to do in Rovaniemi in the summer, and with 24 hours of light, there’s no limits to time of action.
Typical daytime temperatures in the summer:
- June: 15 to 20 degrees Celsius
- July: 20 to 25 degrees Celsius
Autumn
First Auroras and first snowfall from August to November
Early August is still considered summer by many, but by the end of the month, it’s definitely autumn. The Northern Lights start appearing in late August, and September and October are ideal Aurora viewing months.
Temperatures start dropping below zero in October, and first snow usually falls at around the same time period. A permanent snow cover is expected in late November.
Autumn leaf colour paints the landscapes in earthy shades, and days are perfect for hiking and other nature related activities, as nights are best reserved for Aurora spotting.
Typical daytime temperatures in the autumn:
- August: 10 to 20 degrees Celsius
- September: 5 to 15 degrees Celsius
- October: 0 to 10 degrees Celsius
- November: -10 to 5 degrees Celsius
Weather and climate

Rovaniemi is part of the arctic region; its climate, however, is subarctic and temperate, characterised by strong seasonal contrasts of dark versus bright and cold versus warm.
