Unlike the long, cold winter, Summer in Finland is a short, magical experience marked by an extraordinary phenomenon on earth, the midnight sun. That is, the sun stays on the horizon way past midnight, and the nights turn white.
Whether you are hiking the nature trails or taking a swim in a lake, just go on, even if the clock hits, let’s say 1 am. The wilderness, lakes, cities and the coast are all bright and vivid for you to explore. And the temperatures resemble nothing like the summer heat we know; they pleasantly stay around 10 to 25 °C.
And there’s more: from the south to the far north, Finland has urban life and pure nature in equal measure. Architectural wonders, an endless span of lakes and lush forests, thousands of islands, and the best summer festivals and celebrations await in Finland during the summer.
In this guide, you’ll find out where to go, what to do and how to celebrate a well-planned summer trip to Finland.
Why Visit Finland in Summer?
Visiting Finland in Summer means experiencing long daylight hours and the magical midnight sun. With warm, pleasant weather, it’s the best time to explore Finland’s lakes, forests and national parks. Here’s why:
Daylight Hours and the Midnight Sun
Summer in Finland brings the midnight sun, or nightless nights, when the sun remains visible even at midnight, giving nearly 24 hours of daylight. This phenomenon occurs from mid-May to mid-August, with June marking the longest days.
It is most intense in Lapland as the sun does not set for weeks. And even in the south, the nights never go completely dark, and the sky remains bright.
This extended daylight makes planning your days easier and lets you take on your adventures late into the night.
Average Temperatures and What to Pack
In Finland, summer temperatures are comfortably warm. In Lapland, temperatures range from 10 to 20 °C, and in southern regions like Helsinki and Turku, they go from 15 to 25 °C. Rarely do heat waves push it past 25 °C. So pack strategically:
- Light, breathable clothes and sunglasses
- A light jacket
- A pair of comfortable hiking shoes
- A rain jacket or an umbrella in case of sudden showers
Mosquitoes are a summer nuisance, especially in Finnish Lapland and Lakeland. Shop for a mosquito head net and a repellent once you are in Finland.
Peak Season: Crowds vs. Accessibility
Finland, in general, remains less visited than many other European countries. Finland sees more visitors from June to August than at any other time. The Finns also take their holidays in July and August. Book early for accommodations, activities and festivals.
Try visiting in late May, early June, or late August to balance better weather with fewer crowds.
Finland is easy to get around with public buses, trains and ferries. The overall infrastructure is very accommodating for senior citizens and differently-abled people. Even many national parks offer easy, wheelchair accessible trails.
Top Destinations to Visit During Summer in Finland
Finland has four key regions, each with its own defining landscapes and seasonal highlights. Here are the best places to visit in Finland during the summer:
1. Helsinki
The capital city features both historical and modern architecture. Here are the ones that stand out;
Helsinki Cathedral
With its impressive white facade and green domes, the Cathedral stands tall at the heart of the city. You can enjoy its neoclassical design and peaceful interior.
The wide steps in front of the cathedral are where people love to gather, which provides an elevated view of the city and the harbour. Opening hours vary, so it’s best to check the official website before visiting.
Temppeliaukio Church
This ‘Rock Church’ perfectly blends nature and design, with its copper dome carved into granite bedrock. Sunlight coming through the dome creates a magical atmosphere inside.
The church has excellent acoustics, thanks to the granite surfaces left exposed. Visit the official website for entry fees and opening hours.
Suomenlinna Sea Fortress
Suomenlinna is an 18th-century sea fortress that spans across six islands in the Helsinki Archipelago. It was built in the 1700s. Its museums, buildings and bunkers are open for guided tours. And there are many picnic spots overlooking the Baltic Sea.
Entry is free, and you can reach the fortress by a 15-minute HSL ferry from Helsinki Market Square. There are many departures during the summer.
Sibelius Monument
Dedicated to the Finnish composer Jean Sibelius, it has over 600 acid-resistant steel tubes, welded together, resembling organ pipes. You can walk under this 10.5-metre-long sculpture, take pictures and make sounds in the pipes.
Birch trees surround the sculpture in the middle of a seaside park. Cafe Regatta, a popular place for coffee, cinnamon buns and blueberry pies, is also nearby.
2. Lakeland or the Finnish Lake District
Finland is called the land of a thousand lakes, although the actual number goes beyond 180,000. The Finnish Lakeland has most of the lakes, which makes it perfect for water activities like boating and kayaking, as well as lakeside saunas.
Lake Saimaa Region
Lake Saimaa covers more than 4000 square kilometres and flows at the heart of the Finnish Lakeland. In the lake, you can go swimming, canoeing, and take guided boat tours to spot the Saimaa Ringed Seal, which is only found in Saimaa. Cycling, hiking, birdwatching and berry picking are the top things you can do in the wilderness around Lake Saimaa.
Mikkeli
Mikkeli is Finland’s summer cottage capital, defined by lakes and forests. You can rent a cabin by the lake, go swimming, fishing, and have saunas to enjoy the long summer days. Mikkelipuisto Garden Park is a great place to spend a fun evening with your family. Astuvansalmi Rock Paintings and Art Centre Salmela will give you insights into Finnish lake culture.
3. Lapland
Lapland is the northernmost region of Finland and the best place to experience the midnight sun. The region has untouched wilderness and the purest air in the world.
Santa Claus Village
The Santa Claus Village in Rovaniemi is a popular attraction, even in summer. Visitors can meet Santa and send postcards from his post office. And in the central square, there’s a symbolic Arctic Circle line on the pavement, which you can walk across and receive a certificate as a souvenir.
Inari
Inari in Lapland is the cultural heart of the Sami people. It is best to get to know them and their way of life for you to appreciate the origins of the Nordic people.
In Inari, you can visit Siida, an open-air museum exhibiting Sami Life. Access to the indoor and outdoor exhibits requires a paid ticket. The museum is usually open from June 1st to September 25th during the summer, except on Sundays.

Turku Castle and Turku Cathedral
These are two 13th-century historical landmarks in Turku, located 3 kilometres apart along the Aura River. The castle and cathedral document centuries-old Finnish history and architecture. Visit the respective official websites for timings and entry charges. The Aura Riverside is a relaxing place to spend time, with cafes and boat restaurants.
Naantali
Naantali is often called the sunshine city of Finland for its bright summer weather and is adorned with colourful wooden houses and cosy cafes. It is an archipelago town with thousands of islands nearby. You can explore the Archipelago Sea from Naantali by taking boat trips, island-hopping, and seaside walks.

The trail exposes you to Finnish culture and coastal views, allowing you to enjoy a relaxed summer.

Experience the Traditional Finnish Sauna
A traditional Finnish sauna balances humid steam at 80-90 °C, followed by a cooling dip in the lake. This heat-cool-repeat cycle cleanses your mind and body, helping you relax the Finnish way. No Finnish summer trip is complete without a sauna. You can have either a public or private sauna.

There are countless water activities to enjoy across Finland’s coastline and archipelagos.
