Daily Chance of Precipitation
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 in the year. Rankin Inlet experiences significant seasonal variation in monthly rainfall.
The rainy period of the year lasts for 158 days, from May 18 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 August 23, with an average total accumulation of 2.4 inches.
The rainless period of the year lasts for 207 days, from October 23 to May 18. The least rain falls around February 6, with and average total accumulation of 0.0 inches.
Average Monthly Rainfall
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 in the year. Rankin Inlet experiences some seasonal variation in monthly liquid-equivalent snowfall.
The snowy period of the year lasts for 284 days, from September 17 to June 28, with a sliding 31-day liquid-equivalent snowfall of at least 0.1 inches. The most snow falls during the 31 days centered around May 8, with an average total liquid-equivalent accumulation of 0.8 inches.
The snowless period of the year lasts for 81 days, from June 28 to September 17. The least snow falls around August 2, with an average total liquid-equivalent accumulation of 0.0 inches.
Average Liquid-Equivalent Monthly Snowfall
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 Rankin Inlet, 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.
Humidity Comfort Levels
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 Rankin Inlet experiences mildly seasonal variation over the course of the year.
The windier part of the year lasts for 268 days, from September 2 to May 28, with average wind speeds of more than 6.5 miles per hour. The windiest day of the year is October 6, with an average hourly wind speed of 7.7 miles per hour.
The calmer time of year lasts for 97 days, from May 28 to September 2. The calmest day of the year is July 13, with an average hourly wind speed of 5.5 miles per hour.
Average Wind Speed
The predominant average hourly wind direction in Rankin Inlet is from the north throughout the year.
Rankin Inlet is located near a large body of water (e.g., ocean, sea, or large lake). This section reports on the wide-area average surface temperature of that water.

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.

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