A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. In Agassiz, the chance of a wet day over the course of January is decreasing, starting the month at 54% and ending it at 49%.
For reference, the year's highest daily chance of a wet day is 63% on November 18, and its lowest chance is 13% on August 10.
Over the course of January in Agassiz, the chance of a day with only rain remains an essentially constant 44% throughout, the chance of a day with mixed snow and rain decreases from 7% to 5%, and the chance of a day with only snow remains an essentially constant 2% throughout.
Probability of Precipitation in January
To show variation within the month and not just the monthly total, we show the rainfall accumulated over a sliding 31-day period centered around each day.
The average sliding 31-day rainfall during January in Agassiz is decreasing, starting the month at 7.2 inches, when it rarely exceeds 10.8 inches or falls below 3.5 inches, and ending the month at 6.6 inches, when it rarely exceeds 10.5 inches or falls below 2.9 inches.
Average Monthly Rainfall in January
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 January in Agassiz is essentially constant, remaining about 0.4 inches throughout, and rarely exceeding 1.5 inches or falling below -0.0 inches.
The highest average 31-day liquid-equivalent accumulation is 0.5 inches on January 4.

Over the course of January in Agassiz, the length of the day is rapidly increasing. From the start to the end of the month, the length of the day increases by 1 hour, 6 minutes, implying an average daily increase of 2 minutes, 12 seconds, and weekly increase of 15 minutes, 23 seconds.
The shortest day of the month is January 1, with 8 hours, 18 minutes of daylight and the longest day is January 31, with 9 hours, 24 minutes of daylight.
Hours of Daylight and Twilight in January
The latest sunrise of the month in Agassiz is 8:02 AM on January 1 and the earliest sunrise is 23 minutes earlier at 7:39 AM on January 31.
The earliest sunset is 4:19 PM on January 1 and the latest sunset is 43 minutes later at 5:02 PM on January 31.
Daylight saving time is observed in Agassiz during 2017, but it neither starts nor ends during January, so the entire month is in standard time.
For reference, on June 21, the longest day of the year, the Sun rises at 5:01 AM and sets 16 hours, 15 minutes later, at 9:16 PM, while on December 21, the shortest day of the year, it rises at 7:59 AM and sets 8 hours, 11 minutes later, at 4:11 PM.

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 Agassiz is essentially constant during January, remaining around 0% throughout.
For reference, on August 4, the muggiest day of the year, there are muggy conditions 6% of the time, while on January 1, the least muggy day of the year, there are muggy conditions 0% of the time.

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 Agassiz is essentially constant during January, remaining around 2.2 miles per hour throughout.
For reference, on December 29, the windiest day of the year, the daily average wind speed is 2.3 miles per hour, while on August 6, the calmest day of the year, the daily average wind speed is 1.5 miles per hour.

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 in Agassiz is gradually increasing during January, rising by 0.5 kWh, from 0.8 kWh to 1.4 kWh, over the course of the month.

Temperature and Dew Point
There are 2 weather stations near enough to contribute to our estimation of the temperature and dew point in Agassiz.
For each station, the records are corrected for the elevation difference between that station and Agassiz 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 Agassiz is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Agassiz and a given station.
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.
