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. Andenes experiences some seasonal variation in monthly rainfall.

Rain falls throughout the year in Andenes. The most rain falls during the 31 days centered around October 14, with an average total accumulation of 3.2 inches.

The least rain falls around May 13, with and average total accumulation of 1.4 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. Andenes experiences some seasonal variation in monthly liquid-equivalent snowfall.

The snowy period of the year lasts for 6.3 months, from October 22 to April 30, with a sliding 31-day liquid-equivalent snowfall of at least 0.1 inches. The most snow falls during the 31 days centered around January 31, with an average total liquid-equivalent accumulation of 0.8 inches.

Sun

Due to its extreme latitude, Andenes 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 Andenes during 2017, the Sun is continuously above the horizon for 2.2 months, rising at 1:13 AM on May 19, and not setting again until 12:30 AM on July 25.

In the winter in Andenes during 2017, the Sun is continuously below the horizon for 1.5 months, setting at 12:10 PM on November 28, and not rising again until 11:40 AM on January 13.

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 Andenes, 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 Andenes experiences significant seasonal variation over the course of the year.

The windier part of the year lasts for 6.6 months, from October 4 to April 23, with average wind speeds of more than 6.6 miles per hour. The windiest day of the year is January 14, with an average hourly wind speed of 8.7 miles per hour.

The calmer time of year lasts for 5.4 months, from April 23 to October 4. The calmest day of the year is July 30, with an average hourly wind speed of 4.6 miles per hour.

Data Sources

This report illustrates the typical weather in Andenes, 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 are 2 weather stations near enough to contribute to our estimation of the temperature and dew point in Andenes.

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

The estimated value at Andenes is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Andenes and a given station.

The stations contributing to this reconstruction are: Andøya Andenes Airport (100%, 2.6 kilometers, south) and Tromsø Airport, Langnes (0.4%, 117 kilometers, east).

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.

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.
