Weather and climate in Finland

What's the weather like in Finland?

As the saying goes, the climate is what we expect, and the weather is what we get. Finland has four unique seasons. The temperature in Finland varies greatly by season and by region as the country is long and has differing coastal and inland climates. The Atlantic Ocean to the west and the Eurasian continent to the east together create the actively changing climate of Finland.

The hottest month is typically July and the coldest is January and February. Due to our country’s location, the weather can also change quickly, which makes predicting a bit tricky as do the effects of climate change. One moment the sun might be shining, and the next rain is pouring down – such is life up North. We recommend checking the weather in the morning before heading out so you'll know exactly how to dress to be as comfortable and as warm as possible.

Summer weather

Summer in Finland is pleasantly warm and filled with incredible 24h light! In southern Finland, the season usually begins in late May and lasts until mid-September. Summer in Lapland starts about one month later and ends a month earlier than on the south coast. The average summer temperature in Finland is around +20°C / 68°F but especially in southern and central parts of the country, it can get much warmer than that.

Autumn weather

The season of autumn and its beautiful foliage ('ruska' in Finnish) begins around the last week of August in Lapland and about one month later in southwestern Finland. Autumn typically brings a rainier climate to Finland, especially in the coastal areas. The first snow usually falls in Lapland in September and elsewhere in October or November.

Winter weather

Winter is the longest season in Finland. It lasts for about 200 days in Lapland and 3-4 months in southern Finland. The temperature in northern Finland is typically below zero Celsius degrees for most of winter and a bit warmer down south. The whole country is likely to be covered in snow, which turns Finland into a winter wonderland. The Northern Lights are the most vivid under the dark winter skies.

Spring weather

The short yet distinct spring in Finland revives nature (and people!) back to life with increasing sunlight. The season begins early in April on the Coast and the Archipelago and later in April elsewhere, except for northernmost Lapland, where the season kicks off a month later in early May. The highlight of spring is the 1st of May, when Finns flock to parks all across the country for picnics – no matter the weather!

How to dress in Finland?

Change is the keyword when it comes to the climate and weather in Finland. Changes often happen within a single day – from a rainy summer morning to hot and sunny summer evening – and from season to season.

Our best advice is to dress for the likeliest weather and to wear layers that you can take off or add on, when needed. It's good to always check the day's weather before heading out. We listed the monthly average temperatures in different regions below to give you some indication of what to expect. As a rule of thumb, it’s never a bad idea to pack extra layers to keep you warm and protect you from the rain and the wind. It’s way more fun to explore new places feeling comfortable! Good, weather-appropriate shoes are also a must.

Monthly weather

What to pack in winter: warm gloves, a beanie, a scarf, woolly socks, winter boots, and a thick jacket are essential.


Weather in Finland in January

January is the prime time of winter and the whole country is, most often, covered with snow. The coldest day of the season is usually at the end of January in most regions. Our recommendation is to dress (very!) warmly. A layer of woolly undergarments does wonders for extra insulation, and windproof outerwear protects you from that cool winter breeze, especially in the coast. In January, the days are short. In Helsinki, the sun sets around 4pm and in northern Lapland the sun doesn't rise at all during the beginning of January. This season is called 'kaamos' in Finnish – an excellent time to spot the Northern Lights!

The average temperature in January 2021

Rovaniemi -13.1°C / 8.6°F
Tampere -5.4°C / 22.3°F
Turku -4.1°C / 24.6°F
Helsinki -3.5°C / 25.7°F

Weather in Finland in February

February is a snowy and chilly winter month in all of Finland. The slower cooling of the Baltic Sea typically delays the coldest period on the Coast and the Archipelago until the beginning of February. The days are still relatively short but they are getting longer – on average, the sun stays up for nine hours in Helsinki.

Weather in Finland in April

After the long winter nature wakes up again in April. Spring begins early in the month in the coastal areas, and later in April elsewhere, except for the northernmost Lapland, where the season awaits itself for a few more weeks. Spring-time skiing in Lapland is a memorable experience. In April, there’s an increasing amount of daylight and the snow starts to melt, yet it is still not summer. Dressing up in layers is still highly recommended!

Rovaniemi 0.9°C / 33.6°F
Tampere 3.6°C / 38.5°F

Weather in Finland in May

May in Finland kicks off with the 1st of May (Vappu) celebrations. The temperature in May fluctuates from warm to cool, so be prepared for almost any given weather. What’s certain, however, is the ever-increasing amount of daylight. In Lapland, the month of May marks the start of the Midnight Sun period, which means the Sun just dips in the sky at night until July.

Rovaniemi 5.5°C / 41.9°F
Tampere 9.7°C / 49.5°F
Turku 9.9°C / 49.8°F
