A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Amos varies throughout the year.

The wetter season lasts 6.1 months, from May 14 to November 18, with a greater than 28% chance of a given day being a wet day. The chance of a wet day peaks at 41% on July 8.

The drier season lasts 5.9 months, from November 18 to May 14. The smallest chance of a wet day is 16% on February 19.

Among wet days, we distinguish between those that experience rain alone, snow alone, or a mixture of the two. Based on this categorization, the most common form of precipitation in Amos changes throughout the year.

Rain alone is the most common for 7.8 months, from March 24 to November 16. The highest chance of a day with rain alone is 41% on July 8.

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. Amos experiences significant seasonal variation in monthly rainfall.

The rainy period of the year lasts for 8.9 months, from March 12 to December 8, 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 3.4 inches.

The rainless period of the year lasts for 3.1 months, from December 8 to March 12. The least rain falls around February 7, with an average total accumulation of 0.1 inches.

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. Amos experiences significant seasonal variation in monthly liquid-equivalent snowfall.

The snowy period of the year lasts for 7.2 months, from October 9 to May 14, with a sliding 31-day liquid-equivalent snowfall of at least 0.1 inches. The most snow falls during the 31 days centered around December 25, with an average total liquid-equivalent accumulation of 1.1 inches.

The snowless period of the year lasts for 4.8 months, from May 14 to October 9. The least snow falls around August 5, with an average total liquid-equivalent accumulation of 0.0 inches.

The length of the day in Amos varies extremely over the course of the year. In 2017, the shortest day is December 21, with 8 hours, 17 minutes of daylight; the longest day is June 21, with 16 hours, 8 minutes of daylight.

The earliest sunrise is at 5:09 AM on June 16, and the latest sunrise is 2 hours, 55 minutes later at 8:04 AM on January 1. The earliest sunset is at 4:16 PM on December 11, and the latest sunset is 5 hours, 2 minutes later at 9:18 PM on June 25.

Daylight saving time (DST) is observed in Amos during 2017, starting in the spring on March 12, lasting 7.8 months, and ending in the fall on November 5.

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 Amos, 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, staying within 3% of 3% 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 Amos experiences mild seasonal variation over the course of the year.

The windier part of the year lasts for 6.6 months, from October 27 to May 15, with average wind speeds of more than 3.3 miles per hour. The windiest day of the year is February 27, with an average hourly wind speed of 3.9 miles per hour.

The calmer time of year lasts for 5.4 months, from May 15 to October 27. The calmest day of the year is July 31, with an average hourly wind speed of 2.7 miles per hour.

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

The wind is most often from the north for 4.3 months, from February 10 to June 18, with a peak percentage of 40% on April 13.

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. Shortwave radiation includes visible light and ultraviolet radiation.

The average daily incident shortwave solar energy experiences extreme seasonal variation over the course of the year.

The brighter period of the year lasts for 3.6 months, from April 30 to August 19, with an average daily incident shortwave energy per square meter above 5.2 kWh. The brightest day of the year is June 28, with an average of 6.3 kWh.

Temperature and Dew Point

There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Amos.

For each station, the records are corrected for the elevation difference between that station and Amos 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 Amos is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Amos and a given station.

The stations contributing to this reconstruction are: Val-d'Or Airport (45%, 62 kilometers, southeast); Rouyn-Noranda Airport (41%, 67 kilometers, southwest); and Matagami Airport (14%, 135 kilometers, north).

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.
