The transitions to and from daylight saving time are indicated by the 'DST' labels.

Humidity

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 Farmington, 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.

Wind

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 windier part of the year lasts for 4.3 months, from February 16 to June 25, with average wind speeds of more than 4.2 miles per hour. The windiest day of the year is April 11, with an average hourly wind speed of 5.1 miles per hour.

The calmer time of year lasts for 7.7 months, from June 25 to February 16. The calmest day of the year is August 15, with an average hourly wind speed of 3.3 miles per hour.

Solar Energy

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 extreme seasonal variation over the course of the year.

The brighter period of the year lasts for 2.7 months, from April 29 to July 20, with an average daily incident shortwave energy per square meter above 7.4 kWh. The brightest day of the year is June 12, with an average of 8.6 kWh.

The darker period of the year lasts for 3.4 months, from November 2 to February 12, with an average daily incident shortwave energy per square meter below 4.0 kWh. The darkest day of the year is December 22, with an average of 2.8 kWh.

Data Sources

This report illustrates the typical weather in Farmington, 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 2 weather stations near enough to contribute to our estimation of the temperature and dew point in Farmington.

For each station, the records are corrected for the elevation difference between that station and Farmington 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 Farmington is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Farmington and a given station.

The stations contributing to this reconstruction are: Four Corners Regional Airport (100%, 2.0 kilometers, northwest) and Window Rock Airport (0.4%, 141 kilometers, southwest).

Other Data

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.
