A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Ogden varies throughout the year.
The wetter season lasts 234 days, from October 17 to June 8, with a greater than 17% chance of a given day being a wet day. The chance of a wet day peaks at 27% on April 30.
The drier season lasts 131 days, from June 8 to October 17. The smallest chance of a wet day is 7% on July 4.
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 throughout the year is rain alone, with a peak probability of 26% on April 30.
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. Ogden experiences some seasonal variation in monthly rainfall.
The rainy period of the year lasts for 344 days, from July 23 to July 2, with a sliding 31-day rainfall of at least 0.5 inches. The most rain falls during the 31 days centered around May 11, with an average total accumulation of 1.8 inches.
The rainless period of the year lasts for 21 days, from July 2 to July 23. The least rain falls around July 12, with and average total accumulation of 0.5 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. Ogden experiences some seasonal variation in monthly liquid-equivalent snowfall.
The snowy period of the year lasts for 128 days, from November 9 to March 17, with a sliding 31-day liquid-equivalent snowfall of at least 0.1 inches. The most snow falls during the 31 days centered around January 6, with an average total liquid-equivalent accumulation of 0.4 inches.
The snowless period of the year lasts for 237 days, from March 17 to November 9. The least snow falls around July 28, 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 Ogden, 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 Ogden does not vary significantly over the course of the year, remaining within 0.4 miles per hour of 3.1 miles per hour throughout.
Average Wind Speed
The predominant average hourly wind direction in Ogden varies throughout the year.
The wind is most often from the west for 141 days, from March 22 to August 10 and for 34 days, from September 6 to October 10, with a peak percentage of 37% on May 3. The wind is most often from the south for 27 days, from August 10 to September 6 and for 163 days, from October 10 to March 22, with a peak percentage of 54% on January 10.
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 very significant seasonal variation over the course of the year.
The brighter period of the year lasts for 93 days, from May 16 to August 17, with an average daily incident shortwave energy per square meter above 7.1 kWh. The brightest day of the year is June 29, with an average of 8.4 kWh.
The darker period of the year lasts for 108 days, from October 30 to February 15, with an average daily incident shortwave energy per square meter below 3.4 kWh. The darkest day of the year is December 21, with an average of 2.1 kWh.

This report illustrates the typical weather in Ogden, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.
Temperature and Dew Point
There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Ogden.
For each station, the records are corrected for the elevation difference between that station and Ogden 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 Ogden is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Ogden and a given station.
The stations contributing to this reconstruction are: Ogden Municipal Airport (96%, 4.3 kilometers, southwest), Logan-Cache Airport (2.5%, 64 kilometers, north), and Evanston-Uinta County Burns Field (1.0%, 79 kilometers, east).
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.
