Using our figures
The month data, hotel room prices and activity prices behind this site are published as files you can download, under a licence that asks one thing in return: say where they came from.
What you can take
Three files, each one built from figures we had already checked for a page on this site.
| File | What is in it | Where it comes from |
|---|---|---|
| lapland-by-month.csv | Twelve rows, one per month: daylight hours, whether the sun clears the horizon, the average low and high, how viable the aurora is, snow cover, how busy it gets, and the date each row was checked | The Finnish Meteorological Institute’s 1991 to 2020 normals, a sun-time calculator read once a month, and Statistics Finland for the crowding |
| lapland-room-prices.csv | Thirty-six rows, one per month from August 2023 to July 2026: the average price paid per occupied hotel room per night, VAT included, in Rovaniemi, in Lapland and in Finland as a whole, and the share of hotel rooms taken in each | Statistics Finland’s accommodation statistics, tables 11ix and 11lm, read from its own API rather than typed, so a refresh is one command |
| lapland-activity-prices.csv | Sixty-two published prices for husky, reindeer, snowmobile and Northern Lights tours, glass-roofed rooms, an ice hotel and lift passes: operator, base, duration, adult and child price, what is included, the date checked, and the page of ours that prints it | Each operator’s own page, or the tourist board’s listing if the price is published there instead. Prices that could not be matched to a source are left out |
Every source is named inside the file itself, so a copy that travels still says where the numbers came from. The prices are the ones published on the day we checked, and operators change them between seasons: check a price with the operator before you rely on it.
The charts and maps
The charts on our pages are drawn from the same checked figures, when the site is built, so a chart and its table cannot disagree. They are under the same licence as the files: reuse one, credit Explore Lapland, and link the page it is on. The maps are drawn on Natural Earth outlines, which are in the public domain. Two of them, as they appear on the month and cost pages:
Source: moisio.fi sun times for Rovaniemi, using the Finnish Meteorological Institute’s definition of sunrise. Checked 17 September 2026.
It is an average over every hotel room in Lapland, in euros, so premium stays cost a good deal more. Glass igloos and luxury trips list what those rooms charge.
Source: Statistics Finland, table 11ix, updated 27 August 2026 (average price per occupied room, hotels). Checked 17 September 2026.
Ten more diagrams to take away
These ten are drawn from public data and broad facts, not from any one operator’s price list, so they date slowly and travel well. Each keeps the source line it carries on its own page. Under each one is a credit line you can paste as it stands; if you redraw the figure, keep the original source in the credit as well as ours.

The licence, in one paragraph
The data is published under CC BY 4.0. You may copy it, change it, chart it and use it commercially. The one condition is attribution: name Explore Lapland, link the page or the file you took it from, and say if you changed anything. You do not need to ask us first, and there is no fee.
The photographs are a different matter. They are licensed to us by the photographers, often under terms that do not transfer, so our licence does not cover them. Each one carries its own credit on the page that shows it, and if you want to use one, go to its source.
Our written pages are not under this licence either. Quote a sentence or two with a link, as anyone would; do not republish a page.
How to cite it
In a chart or a table, one line is enough:
- Explore Lapland, Lapland month by month, CC BY 4.0, https://explore-lapland.com/reuse/
- Explore Lapland, hotel room prices in Lapland by month, from Statistics Finland, CC BY 4.0, https://explore-lapland.com/reuse/
- Explore Lapland, published activity prices in Lapland, CC BY 4.0, https://explore-lapland.com/reuse/
If you are writing about a single figure, cite the page that carries it rather than the file. The month pages name the source of each number and the date we checked it, and a reader chasing the figure will want both.
Why we publish it at all
We compiled these numbers after failing to find them in one place. A month page that says “about four hours of daylight in January” is only worth reading if the four hours came from somewhere, and the easiest way to prove that is to hand over the whole table.
It also keeps us honest. A figure that is wrong in a file anyone can download is wrong in public. The editorial policy covers how corrections are handled.
