Rainfall

To show variation within the months and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day of the year. Kiruna experiences significant seasonal variation in monthly rainfall.

The rainy period of the year lasts for 5.9 months, from April 25 to October 23, with a sliding 31-day rainfall of at least 0.5 inches. The most rain falls during the 31 days centered around July 15, with an average total accumulation of 3.5 inches.

The rainless period of the year lasts for 6.1 months, from October 23 to April 25. The least rain falls around January 19, with an average total accumulation of 0.0 inches.

Average Monthly Rainfall

The average rainfall (solid line) accumulated over the course of a sliding 31-day period centered on the day in question, with 25th to 75th and 10th to 90th percentile bands. The thin dotted line is the corresponding average liquid-equivalent snowfall.

Snowfall

We report snowfall in liquid-equivalent terms. The actual depth of new snowfall is typically between 5 and 10 times the liquid-equivalent amount, assuming the ground is frozen. Colder, drier snow tends to be on the higher end of that range and warmer, wetter snow on the lower end.

As with rainfall, we consider the snowfall accumulated over a sliding 31-day period centered around each day of the year. Kiruna experiences some seasonal variation in monthly liquid-equivalent snowfall.

The snowy period of the year lasts for 8.5 months, from September 17 to June 2, with a sliding 31-day liquid-equivalent snowfall of at least 0.1 inches. The most snow falls during the 31 days centered around November 9, with an average total liquid-equivalent accumulation of 0.8 inches.

The snowless period of the year lasts for 3.5 months, from June 2 to September 17. The least snow falls around July 21, with an average total liquid-equivalent accumulation of 0.0 inches.

Sun

Due to its extreme latitude, Kiruna experiences polar day (also known as the midnight Sun) during the summer and polar night during the winter. These are periods of time in which the sun is continuously above or below the horizon for more than one day. The precise start and end dates of polar day and night vary from year to year and depend on the precise location and elevation of the observer, and the local topography.

In the summer in Kiruna during 2017, the Sun is continuously above the horizon for 1.7 months, rising at 12:44 AM on May 27, and not setting again until 12:23 AM on July 17.

In the winter in Kiruna during 2017, the Sun is continuously below the horizon for 3.1 weeks, setting at 11:41 AM on December 10, and not rising again until 11:38 AM on January 1.

Hours of Daylight and Twilight

The number of hours during which the Sun is visible (black line). From bottom (most yellow) to top (most gray), the color bands indicate: full daylight, twilight (civil, nautical, and astronomical), and full night.

Daylight saving time (DST) is observed in Kiruna during 2017, starting in the spring on March 26, lasting 7.1 months, and ending in the fall on October 29.

The solar day over the course of the year 2017. From bottom to top, the black lines are the previous solar midnight, sunrise, solar noon, sunset, and the next solar midnight. The day, twilights (civil, nautical, and astronomical), and night are indicated by the color bands from yellow to gray. The transitions to and from daylight saving time are indicated by the 'DST' labels.

Humidity

We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.

The perceived humidity level in Kiruna, as measured by the percentage of time in which the humidity comfort level is muggy, oppressive, or miserable, does not vary significantly over the course of the year, remaining a virtually constant 0% throughout.

Wind

This section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages.

The average hourly wind speed in Kiruna experiences mild seasonal variation over the course of the year.

The windier part of the year lasts for 6.5 months, from November 24 to June 8, with average wind speeds of more than 3.9 miles per hour. The windiest day of the year is January 23, with an average hourly wind speed of 4.5 miles per hour.

The calmer time of year lasts for 5.5 months, from June 8 to November 24. The calmest day of the year is August 12, with an average hourly wind speed of 3.2 miles per hour.

Average Wind Speed

The average of mean hourly wind speeds (dark gray line), with 25th to 75th and 10th to 90th percentile bands.

The predominant average hourly wind direction in Kiruna varies throughout the year.

Solar Energy

This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents.

Data Sources

This report illustrates the typical weather in Kiruna, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.

Temperature and Dew Point

There is only a single weather station, Kiruna Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Kiruna.

At a distance of 6 kilometers from Kiruna, closer than our threshold of 150 kilometers, this station is deemed sufficiently nearby to be relied upon as our primary source for temperature and dew point records.

The station records are corrected for the elevation difference between the station and Kiruna according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.

Please note that the station records themselves may additionally have been back-filled using other nearby stations or the MERRA-2 reanalysis.

Other Data

All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Tables of the Sun, Moon and Planets , by Jean Meeus.

All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis . This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid.

Land Use data comes from the Global Land Cover SHARE database , published by the Food and Agriculture Organization of the United Nations.

Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory.
