Solar Elevation on April 2, 2020
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.
Muggy conditions are essentially unheard-of in Athabasca on April 2.

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 Athabasca on April 2 varies throughout the day, with a daily average of 7.8 miles per hour.
The windiest time of day is around 1:30 PM, with an average hourly wind speed of 9.4 miles per hour, mostly staying between 6.1 miles per hour and 12.2 miles per hour, and rarely falling below 4.0 miles per hour or exceeding 15.7 miles per hour.
The calmest time of day is around 5:15 AM, with an average hourly wind speed of 6.8 miles per hour, mostly staying between 4.9 miles per hour and 8.5 miles per hour, and rarely falling below 3.5 miles per hour or exceeding 10.7 miles per hour.
For reference, on April 13, the windiest day of the year, the daily average wind speed is 7.8 miles per hour, while on August 1, the calmest day of the year, the daily average wind speed is 6.3 miles per hour.
Wind Speed on April 2

Shortwave Solar Power
This section discusses the incident shortwave solar power 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. Shortwave radiation includes visible light and ultraviolet radiation.
The peak incident shortwave solar power per square meter is 0.52 kilowatts at around 12:45 PM.
In contrast, the corresponding value on July 5, the brightest day of the year, is 0.68 kilowatts at around 12:15 PM. The corresponding value on December 19, the darkest day of the year, is 0.14 kilowatts at around 11:30 AM.

Temperature and Dew Point
There are 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Athabasca.
For each station, the records are corrected for the elevation difference between that station and Athabasca 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 Athabasca is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Athabasca and a given station.
The stations contributing to this reconstruction are: Atmore AGDM (52%, 31 kilometers, east); Abee AGDM (23%, 52 kilometers, southeast); Athabasca Airport (18%, 62 kilometers, southwest); and Slave Lake Airport (7%, 115 kilometers, northwest).
All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Algorithms 2nd Edition , 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.
