A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Culver varies throughout the year.
The wetter season lasts 7.3 months, from October 22 to June 1, with a greater than 20% chance of a given day being a wet day. The chance of a wet day peaks at 34% on November 28.
The drier season lasts 4.7 months, from June 1 to October 22. The smallest chance of a wet day is 6% on August 6.
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 28% on November 21.

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 of the year. Culver experiences some seasonal variation in monthly liquid-equivalent snowfall.
The snowy period of the year lasts for 3.6 months, from November 8 to February 27, 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 24, with an average total liquid-equivalent accumulation of 0.4 inches.
The snowless period of the year lasts for 8.4 months, from February 27 to November 8. The least snow falls around August 7, with an average total liquid-equivalent accumulation of 0.0 inches.

Sunrise & Sunset with Twilight and Daylight Saving Time
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 Culver, 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.

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 Culver experiences mild seasonal variation over the course of the year.
The windier part of the year lasts for 7.8 months, from October 27 to June 22, with average wind speeds of more than 6.5 miles per hour. The windiest day of the year is December 1, with an average hourly wind speed of 7.5 miles per hour.
The calmer time of year lasts for 4.2 months, from June 22 to October 27. The calmest day of the year is August 23, with an average hourly wind speed of 5.6 miles per hour.
Average Wind Speed
The predominant average hourly wind direction in Culver varies throughout the year.

This report illustrates the typical weather in Culver, 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 6 weather stations near enough to contribute to our estimation of the temperature and dew point in Culver.
For each station, the records are corrected for the elevation difference between that station and Culver 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 Culver is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Culver and a given station.
The stations contributing to this reconstruction are: Roberts Field-Redmond Municipal Airport (68%, 31 kilometers, south); The Dalles Municipal Airport (8%, 122 kilometers, north); Aurora State Airport (6%, 147 kilometers, northwest); McNary Field (6%, 148 kilometers, west); Portland–Troutdale Airport (6%, 148 kilometers, northwest); and Mahlon Sweet Field Airport (5%, 166 kilometers, west).
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.

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.
