Finland’s Climate Overview
Finland is a country of dramatic seasonal changes. You’ll experience everything from cold, snowy winters to pleasantly mild summers. The climate is classified as continental, meaning you get warm summers and cold winters, with rainfall spread out fairly evenly throughout the year.
Most of the country falls into this pattern, but Northern Finland can get colder and snowier, particularly in the area known as Lapland. The southern regions, including Helsinki, tend to be milder.
Traveling in Finland really depends on what activities you’re into. Some people love visiting during the colder months for winter sports, while others prefer the warmer seasons when outdoor hiking and lakeside activities rule. Let’s break down the weather, month by month, so you can decide when to visit.
Finland’s Weather in January
January in Finland is cold. In fact, it’s the coldest month of the year. Temperatures in the south hover around -4°C (24°F), but it can dip much lower, especially in Lapland, where it can drop to -15°C (5°F) or colder.
There’s a lot of snow on the ground, and with such short daylight hours (only a few hours of daylight in the northern parts), it can feel like there’s more night than day. But January is also prime time for seeing the Northern Lights and enjoying snow sports like skiing or husky sledding.
What to Pack for January
Be prepared for sub-zero temperatures. Bring thermal layers, thick socks, a warm hat, gloves, a scarf, and a heavy winter jacket. Snow boots are also a good idea if you plan to be outdoors for long periods.
Finland’s Weather in February

February offers much of the same as January—cold and snow-covered. Temperatures stay low, particularly in the north, where it remains well below freezing. You might get a little more daylight, but it’s still winter at its core.
However, travel in Finland during February can be great for those wanting to enjoy skiing, snowboarding, or a trip to a winter festival. The Northern Lights can still be seen clearly in Lapland.
What to Pack for February
Layering is key to staying warm. Pack thermal clothing, a warm winter coat, insulated gloves, and snow boots. Don’t forget a hat and scarf to keep out the cold.
Finland’s Weather in March
March brings a little more daylight and warmer weather, but it’s still winter, especially in the north. Temperatures in the south may rise to 0°C (32°F) or slightly above, but northern Finland still experiences chilly conditions, with temperatures around -10°C (14°F).
It’s a great time for skiing and other snow-related activities. The longer days make it more pleasant to be outside, and there’s still a good chance of seeing the Northern Lights in Lapland.
What to Pack for March
Winter clothes are still necessary—a warm coat, thermal layers, boots, gloves, and a hat. You may not need as many layers as earlier in the year, but erring on the side of caution is better than being cold.
Finland’s Weather in April
April signals the start of spring, at least in southern Finland. Temperatures rise to 5°C to 10°C (40°F to 50°F), though some areas may still feel chilly. There’s less snow, but it’s not quite warm enough to be considered proper spring. In the north, April can still feel wintry with snow lingering in Lapland.

If you’re planning to visit Helsinki or other southern cities, this is when locals start venturing outdoors more. Hiking trails nearer to the cities begin to clear up.

What to Pack for April
A mix of winter and lighter clothing works well. Bring a warm jacket and layers, as mornings and nights can still be cold. Wear waterproof shoes as melted snow makes things slushy.
Finland’s Weather in May
May is the start of a more noticeable spring in Finland. You’ll see temperatures between 8°C and 16°C (46°F and 60°F). Flowers start blooming, and snow is usually gone from the ground (except high-altitude places in the north).
May is a good time for hiking and exploring Finland’s national parks before the summer crowds arrive. Plus, days are getting much longer: you’ll have 10 to 15 hours of daylight, depending on where you are.

What to Pack for May
Spring clothing like jackets, sweaters, and comfortable travel shoes work well. Bring a rain jacket or umbrella too, as the spring months are typically wetter.
Finland’s Weather in June
Summer starts in June, with temperatures ranging from 12°C to 20°C (54°F to 68°F). In the south, it can be warm and lovely, but Lapland is still cool. June is famous for the start of the “Midnight Sun” in the north, where the sun doesn’t set for weeks on end. Consider Finland’s Midsummer celebrations if you’re around during the solstice.
This month is popular for outdoor activities ranging from hiking in national parks to exploring the thousands of lakes. The days are long, and outdoor cafes start buzzing.

What to Pack for June
Light layers are all you need. A light jacket for cooler evenings, comfortable shoes for exploring, and a hat to protect yourself from the sun. Don’t forget sunscreen—even if it’s not too warm, the Midnight Sun means a lot of exposure.
Finland’s Weather in July
July is Finland’s warmest month. Temperatures can climb as high as 25°C (77°F) in the south, though it’s cooler further north. It’s peak tourist season, especially in coastal areas and the lake district.
July is perfect for hiking, swimming, canoeing, and experiencing Finland’s sauna culture. If you’re not into crowds, though, avoid the major cities and head into the countryside instead.
What to Pack for July
Pack light. T-shirts, shorts, and comfortable walking shoes are essential. A light jacket can still come in handy for cooler evenings. Don’t forget sunscreen, sunglasses, and swim gear if you’re planning to hit the lakes.
Finland’s Weather in August
August is still summer, but a tiny bit cooler compared to July. Temperatures remain between 15°C and 22°C (59°F to 72°F). While it’s still warm, this is when the first signs of fall start to creep in, especially in northern areas.
It’s a great time for outdoor adventures, as the weather is pleasant but without the busyness of July. You may also find Finnish harvest markets popping up across the country.
What to Pack for August
Light layers are perfect. Think shorts, t-shirts, and a light jacket for evenings. A small umbrella or raincoat might be helpful since August can bring some showers.
Finland’s Weather in September
September is the beginning of autumn, with cooler days and colorful fall foliage spreading across Finland. In the south, temperatures are still comfortable at around 10°C to 15°C (50°F to 59°F), while it’s cooler in the north.
This month is great if you want quieter hiking trails and lots of cozy cabin stays as Finnish people retreat into their cottages.
What to Pack for September
Pack warm layers since it can get cooler, especially in the evenings. A light jacket, sweaters, and good walking shoes are recommended. Be prepared for wetter weather, so pack a waterproof layer or umbrella.
Finland’s Weather in October
October is the heart of autumn, with temperatures dropping significantly and ranging between 5°C and 10°C (41°F to 50°F). In the north, it’s colder. Winter is just around the corner, and you may even start to see flurries of snow toward the end of the month.
This is a beautiful time if you want to see Finland’s fall foliage at its peak. It’s also a quieter time for travel as the tourist crowds are mostly gone.
What to Pack for October
Bring a warm wardrobe including sweaters, a coat, and waterproof shoes. Layers are important because temperatures fluctuate throughout the day.
Finland’s Weather in November
November is cold and dark, with temperatures starting to feel wintry especially in the north. The south might still escape significant snowfall, but Lapland will be well into the first snows of the season.
If you’re visiting northern Finland, you might get an early glimpse of the Northern Lights. But for general sightseeing, November isn’t the most popular month unless you’re into the quieter, off-season experience.
What to Pack for November
Layers are essential. Pack a winter coat, thermal layers, gloves, a scarf, and a warm hat. You’ll want boots that can handle slush or snow, especially in the north.
Finland’s Weather in December
December means the arrival of winter across Finland. Snow blankets most of the country, and temperatures drop below freezing. In southern areas, it hovers around -1°C to -5°C (30°F to 23°F), but northern areas can reach -15°C (5°F) or less.
This is peak season in Lapland, where you can enjoy reindeer rides, skiing, snowboarding, or visiting Finnish Christmas markets. The country in general gets into the festive spirit, particularly around the holidays.
What to Pack for December
Pack heavy-duty winter clothing. A thick coat, thermal layers, gloves, a winter hat, and snow boots are essential if you’re going to be outside for long periods. If you’re headed to Lapland, pack extra warm gear to handle the colder temps.
Best Time to Visit Finland
The best time to visit Finland really depends on what you want to do. For a traditional winter experience (with snow activities and Northern Lights), visiting between December and March is ideal. If you prefer warmer weather for hiking, swimming, and enjoying the Midnight Sun, go between June and August. If you’re looking for fewer tourists, consider the shoulder seasons of May and September, when the weather is still pleasant but crowds are smaller.
No matter when you visit, Finland offers something unique in every season. Just make sure you’re prepared for the climate to get the most out of your trip!
