For reference, the year's highest daily chance of a wet day is 24% on August 7, and its lowest chance is 4% on February 13.
Probability of Precipitation in March
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. As with rainfall, we consider the liquid-equivalent snowfall accumulated over a sliding 31-day period centered around each day.
The average sliding 31-day liquid-equivalent snowfall during March in Upernavik is essentially constant, remaining about 0.3 inches throughout, and rarely exceeding 0.8 inches or falling below -0.0 inches.
Average Monthly Liquid-Equivalent Snowfall in March
Due to its extreme latitude, Upernavik 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.
Neither polar day nor polar night occur during the month of March.
Over the course of March in Upernavik, the length of the day is very rapidly increasing. From the start to the end of the month, the length of the day increases by 5 hours, 10 minutes, implying an average daily increase of 10 minutes, 21 seconds, and weekly increase of 1 hour, 12 minutes, 27 seconds.
The shortest day of the month is March 1, with 9 hours, 3 minutes of daylight and the longest day is March 31, with 14 hours, 13 minutes of daylight.

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 chance that a given day will be muggy in Upernavik is essentially constant during March, remaining around 0% throughout.

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 Upernavik is gradually decreasing during March, decreasing from 8.1 miles per hour to 7.6 miles per hour over the course of the month.
For reference, on November 10, the windiest day of the year, the daily average wind speed is 11.4 miles per hour, while on July 13, the calmest day of the year, the daily average wind speed is 6.7 miles per hour.

Definitions of the growing season vary throughout the world, but for the purposes of this report, we define it as the longest continuous period of non-freezing temperatures (≥ 32°F) in the year (the calendar year in the Northern Hemisphere, or from July 1 until June 30 in the Southern Hemisphere).
The growing season in Upernavik typically lasts for 2.7 months (81 days), from around June 19 to around September 9, rarely starting before May 30 or after July 18, and rarely ending before August 14 or after September 28.
The month of March in Upernavik is reliably fully outside of the growing season.

Growing degree days are a measure of yearly heat accumulation used to predict plant and animal development, and defined as the integral of warmth above a base temperature, discarding any excess above a maximum temperature. In this report, we use a base of 50°F and a cap of 86°F.
The average accumulated growing degree days in Upernavik are essentially constant during March, remaining around 0°F throughout.

Temperature and Dew Point
There is only a single weather station, Upernavik Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Upernavik.
At a distance of 2 kilometer from Upernavik, 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 Upernavik 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.
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.

We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series. While having the tremendous advantages of temporal and spatial completeness, these reconstructions: (1) are based on computer models that may have model-based errors, (2) are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and (3) have particular difficulty with the weather in some coastal areas, especially small islands.
We further caution that our travel scores are only as good as the data that underpin them, that weather conditions at any given location and time are unpredictable and variable, and that the definition of the scores reflects a particular set of preferences that may not agree with those of any particular reader.
