No regions match these filters. Try another place or reset the filters.
Cost words compare a published regional accommodation level with Finland's typical level, or describe a region's price season against its own year. The Cost score still uses Finland's price level on the Europe scale; where regional money levels are unavailable, a cheaper season does not establish which region has the cheapest rooms.
What goes into the scores?
Overall combines weather, crowds and cost. It is not a weather rating. By default, the list ranks weather first and shows Balanced Overall scores (50% weather, 30% crowds, 20% cost). Other priorities order it by your Overall mix. Missing cost is excluded and the available parts are reweighted.
Visitor season compares each region with its own year. A higher crowd score does not establish which place has fewer people in absolute terms. Regions cover whole statistical areas; open a guide for its geographic scope. Read the scoring method.

Hotel prices
About usual.
−4% on Finland's historical national hotel-price index, versus its usual month in 2024–2025. This describes a price season, not a live room quote.
Published regional accommodation revenue per occupied unit per night ranges from €105 in Southern Finland to €118 in Helsinki. Southern Finland uses the 2024–2025 monthly average. Historical averages, not booking quotes. Includes hotels and other registered accommodation, with VAT. Coverage and rental units.
Thinking about the coast?
Check the water, too.
Among beach-focused regions, the warmest measured seas this month are Southern Finland (59°F), Åland (58°F), Finnish Lapland & the east (56°F). Sea temperature is one part of a beach trip; open a region for weather and seasonal closures.

How we know Sources, scope & limitations
Each row is a statistical region (NUTS 2); open it for the full month, the sources and what moving your dates would change. National lines are built from the regions: season is Finland's total tourist nights this month against its busiest month (Eurostat, primarily 2024–2025; earlier published years where needed); weather counts regions whose displayed Weather score is at least 7.0/10 (very good or better) rather than averaging across the country; visitors ranks overnight visitors per resident against all Europe's regions (for a region) or the other countries (for Finland) that month.
A regional accommodation level is shown only where publishable money data exists; elsewhere the cost words describe a regional season against its own year, and the score starts from the national price level. Separately, Finland's 2024 restaurants-and-hotels level is above EU average (127 where the EU average is 100). Full method.
