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 Los Alamos is essentially constant during July, remaining around 0% throughout.
For reference, on July 5, the muggiest day of the year, there are muggy conditions 0% 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 Los Alamos is essentially constant during July, remaining within 0.2 miles per hour of 4.4 miles per hour throughout.
For reference, on May 9, the windiest day of the year, the daily average wind speed is 5.5 miles per hour, while on August 10, the calmest day of the year, the daily average wind speed is 4.1 miles per hour.

Los Alamos is located near a large body of water (e.g., ocean, sea, or large lake). This section reports on the wide-area average surface temperature of that water.
The average surface water temperature in Los Alamos is gradually increasing during July, rising by 2°F, from 58°F to 60°F, over the course of the month.

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 Los Alamos is essentially constant during July, remaining within 0.2 kWh of 8.3 kWh throughout.

This report illustrates the typical weather in Los Alamos year round, 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 Los Alamos.
For each station, the records are corrected for the elevation difference between that station and Los Alamos 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 Los Alamos is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Los Alamos and a given station.
The stations contributing to this reconstruction are: Lompoc Airport (30%, 19 kilometers, southwest); Santa Maria Airport (30%, 23 kilometers, northwest); and Santa Ynez Airport (40%, 24 kilometers, southeast).
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.
