A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Luray varies throughout the year.
The wetter season lasts 141 days, from April 10 to August 29, with a greater than 29% chance of a given day being a wet day. The chance of a wet day peaks at 39% on May 29.
The drier season lasts 224 days, from August 29 to April 10. The smallest chance of a wet day is 18% on October 20.
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 39% on May 29.
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. Luray experiences some seasonal variation in monthly rainfall.
Rain falls throughout the year in Luray. The most rain falls during the 31 days centered around May 17, with an average total accumulation of 3.5 inches.
The least rain falls around January 10, with and average total accumulation of 1.6 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. Luray experiences some seasonal variation in monthly liquid-equivalent snowfall.
The snowy period of the year lasts for 129 days, from November 18 to March 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 February 6, with an average total liquid-equivalent accumulation of 0.6 inches.
The snowless period of the year lasts for 236 days, from March 27 to November 18. The least snow falls around July 25, 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.
Luray experiences very significant seasonal variation in the perceived humidity.
The muggier period of the year lasts for 121 days, from May 25 to September 23, during which time the comfort level is muggy, oppressive, or miserable at least 17% of the time. The muggiest day of the year is July 20, with muggy conditions 66% of the time.
The least muggy day of the year is December 20, when muggy conditions are essentially unheard of.

This report illustrates the typical weather in Luray, 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 Luray.
For each station, the records are are corrected for the elevation difference between that station and Luray 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 Luray is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Luray and a given station.
The stations contributing to this reconstruction are: Culpeper County Airport (18%, 54 kilometers, east), Charlottesville-Albemarle Airport (17%, 59 kilometers, south), Shenandoah Valley Regional Airport (17%, 59 kilometers, southwest), Orange County Airport (17%, 59 kilometers, southeast), Winchester Regional Airport (17%, 60 kilometers, northeast), and Grant County Airport (13%, 70 kilometers, northwest).
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.
