Daily Weather Data

NMSU Agricultural Science Center at Farmington, New Mexico has collected weather data since 1969. The weather station was designated an official National Weather Station climatological observation site in 1978. Weather observations are collected daily at 8:00 a.m. and electronically reported to the National Oceanic & Atmospheric Administration (NOAA). The data reported to NOAA are over a 24 hour period from 8:00 a.m. previous day to 8:00 a.m. present day.

The air temperature readings are derived from thermometers mounted at the weather station. Soil temperature readings are derived from a maximum/minimum thermometer via sensor probe buried 4 inches deep into bare ground. Precipitation data are collected in a standard eight-inch rain gauge. Evaporation measurements are collected from a Class-A metal pan. Wind movement is recorded in miles per day. The data are collected from two separate three-cup anemometers, at different heights. The high wind movement is collected from 2 meters above the soil surface while the low wind movement is collected from an anemometer position 18 inches above the base of the evaporation pan.

2023 total precipitation recorded at NMSU's ASC Farmington official National Weather Observation site January - December 2023 was 5.31 inches. Mean precipitation from 1969 - 2023 was 7.86 inches.

Weather data recorded at NMSU's Agricultural Science Center - Farmington is displayed in html format. Requests for the current monthly weather data report or yearly archived reports in PDF format may be requested via email from Margaret West, Research Scientist, NMSU ASC Farmington.

        Climatology

        Plant growth and crop production are intrinsically linked to climate and daily weather conditions. Climate determines the types of plants that can be grown in a particular area and the management techniques required for successful landscapes and agricultural sustainability. Weather affects crop water requirements, timing of planting, cultivation, fertilization and harvest, crop tolerance to disease and pests, total crop yield and product quality. Agricultural and landscape planning begins with a thorough understanding of a locale's climate. To help provide this understanding for the Four Corners region, daily weather observations have been made since 1969 at the New Mexico State University (NMSU) Agricultural Science Center at Farmington (ASCF).

        The ASCF is located in northwestern New Mexico (36 degrees 4' N Lat., 108 degrees 2' W Long.) about seven miles southwest of Farmington at an elevation of 5,640 feet above mean sea level. Two weather-data recording stations are located at the ASCF. Weather Station 1 (WS-1) was established at the center in January 1969 and was given an official designation by the National Weather Service (NWS) in 1978. Weather Station 2 (WS-2) was installed approximately 350 yards south of WS-1 in 1985. This is an automated, computer-linked station that is operated and maintained by the New Mexico Climate Center (NMCC) at NMSU in Las Cruces.

          IMPACT

          Given the marginal precipitation—averaging just 8 inches per year in the New Mexico Four Corners region—local industries and municipalities rely on surface water from the San Juan, Animas, and La Plata Rivers, which converge in Farmington, NM, and then flow into the Colorado River at Lake Powell in Utah. This water-use is regulated for natural resources, agricultural, industrial, municipal, and residential use. Diligent weather data collection and subsequent monitoring from the New Mexico State University Agricultural Science Center at Farmington’s National Weather Service Station 1 (WS-1) and the New Mexico Climate Center Station 2 (WS-2) is crucial to inform those interested in global and regional environments and local economic impacts within the region. Weather data are used by the U.S. Department of Agriculture Natural Resources Conservation Service (USDA–NRCS) San Juan District, large and small acreage agricultural producers, and municipalities for water demand planning and monitoring flood events, and by private end-users for irrigation scheduling. Additionally, both weather station datasets are used in agricultural research. This varying and ongoing need for weather data demonstrates the importance of long-term weather monitoring for the region.

          INTRODUCTION

          NMSU’s Agricultural Experiment Station–Agricultural Science Center at Farmington (ASCF) is located 8 miles southwest of Farmington, NM, at 5,640 feet above sea level (36°4’ N by 108° W) on 254 acres of land leased from the Navajo Nation. The daily weather data at ASCF have been recorded since 1969. The National Weather Service (NWS) designated WS-1 as an official climatological observation site in 1978. The WS-1 equipment is enclosed within a 5-foot-high chain link fence and mounted on the bare soil surface. Weather data are manually recorded during a 24-hour period from 8:00 a.m. to 8:00 a.m. Mountain Standard Time.

          The New Mexico Climate Center (NMCC) designated WS-2 was established at ASCF in 1985. It is located approximately 383 yards south of WS-1. It is enclosed in a 5-foot-high chain link fence surrounded by turf. The weather equipment is mounted on a tripod within the fenced area, and the turf is maintained at 2–3 inches. (National Weather Service, 2018). The WS-2 data (precipitation, air and soil temperatures, relative humidity, wind speed, and solar radiation) are stored in a Campbell Scientific data logger housed in a weather-resistant box. The data are recorded every 5 minutes over a 24-hour period from midnight to midnight. The data are electronically transmitted to NMCC, located on NMSU’s main campus in Las Cruces, NM. NMCC weather data are accessible for download at https://weather.nmsu.edu. The weather data summarized in this report are available by request from ASCF via phone at 505-960-7757 (Monday–Friday, except during holiday office closures) or via email at farmingt@nmsu.edu.

          SUMMARY

          The 2023 summary of climatological data shows an average maximum air temperature of 66°F and an average minimum air temperature of 38°F for the year. The extreme maximum air temperature of 97°F occurred in July and the extreme minimum of -4°F occurred in February.

          FREEZE DATES

          In 2023, there were 166 frost-free days (frost temperature ≤32°F) as compared to the 55-year average of 162. There were 174 killing freeze-free days (killing freeze temperature ≤28°F) in 2023 as compared to the 55-year average of 184 killing freeze-free days (Table 3).

          PRECIPITATION

          Precipitation is collected from an NWS 8-inch standard rain gauge located at WS-1. The 2023 precipitation total from January to December was 5.31 inches, and the 55-year average annual precipitation from 1969 through 2023 was 7.86 inches. The lowest monthly precipitation recorded for 2023 was in July and October at 0.03 inches, and the highest was in March at 1.24 inches (Table 4).

          AIR TEMPERATURE

          Average

          The 2023 highest monthly average air temperature of 77°F occurred in July; the 55-year highest monthly mean air temperature of 76°F also occurred in July (Table 5).

          Maximum

          The 2023 highest average monthly maximum air temperature of 93°F occurred in July, which was higher than the 55-year mean monthly maximum air temperature of 91°F in the month of July (Table 6). The 2023 extreme maximum air temperature of 99°F occurred in July. The 55-year extreme maximum air temperature was 103°F and was recorded in July of 1989, 1990, 2003, and 2005 (Table 7).

          Minimum

          The 2023 lowest average monthly minimum air temperature of 23°F occurred in January and December, which was higher than the 55-year average monthly minimum air temperatures of 19°F and 20°F in January and December, respectively (Table 8). The 2023 extreme minimum air temperature of -4°F occurred in February. The 55-year extreme minimum air temperature of -18°F occurred in January of 1971 (Table 9).

          Critical Days

          There were 144 days from January through December with temperatures equal to or below 32°F in 2023; the 55-year average was 140 days. There was one day with temperatures at or below 0°F during the critical months of January, February, and December in 2023, compared to the 55-year average of 1 day in January and 0 days in February and December (Table 10). In the critical months of May through September in 2023, there were 8 days with temperatures of 95°F or above; in comparison, the 55-year average was 12 days. June and July are critical months for 100°F or above; in 2023, there were a total of 0 days as compared to the 55-year average of 1 day (Table 11).

          EVAPORATION

          The evaporation rate is measured using a U.S. Weather Bureau no. 252 hook gauge mounted in a NWS Class-A evaporation pan. Evaporation measurements are taken from April 1 through October 31. The 2023 average evaporation for the seven-month data collection period was 0.325 inches as compared to the 49-year average of 0.329 inches (Table 12). The 2023 seven-month total evaporation was 71.42 inches versus the 49-year average of 69.66 inches (Table 13).

          WIND RUN

          Daily wind speeds are recorded from NWS Nimbus 3-cup anemometers via Nimbus display units. The low wind speed is recorded in miles per day at 6-inch (1980 through March 2019) and 10-inch heights (April 2019 to present) above the evaporation pan rim. The high wind speed is recorded at 79 inches above bare soil. In 2023, April had the highest daily low wind average at 72 miles per day (MPD), while the April monthly average from 1980 through 2023 was 81 MPD (Table 14). The 2023 average daily high wind also occurred in the month of April at 97 MPD as compared to the April average of 141 MPD from 1981–2023 (Table 15).

          SOLAR RADIATION

          Solar radiation data are collected from the NMCC (WS-2) site. The data are stored in a Campbell Scientific data logger that is housed in a protective shelter. The solar radiation is recorded in megajoules per square meter (MJ/m2). Those units are then converted into Langley (ly) units (used in this publication) by using a multiplication factor of 23.89. June 2023 had the highest record Langley units at 629 as compared to the 47-year average for June at 653 (Table 16).

          CORN GROWING DEGREE DAYS

          Corn growing degree days (GDD) are expressed as heat units using air temperatures required for plant growth and developmental stages. The air temperature threshold for corn GDD in this report was determined by using an upper air temperature parameter of 86°F and lower temperature of 50°F. The peak corn GDD from May through September 2023 was in July at 725 GDD, while the 55-year average for July was 718 GDD (Table 17).

          SOIL TEMPERATURE

          Soil maximum and minimum temperatures are collected from a National Oceanic and Atmospheric Administration (NOAA) Weather Service soil sensor probe buried 4 inches below the soil surface. This soil equipment is located outside of the WS-1 fenced area. Due to equipment changes since 1977, the soil data (2001–2023) are a continuation of the dataset contained in O’Neill et al. (2018). All prior year soil temperature data are available upon request from ASCF.

          Average

          The highest average monthly soil temperature from 2001–2023 was in July at 85°F. The extreme maximum average soil temperature was also in July at 99°F. The lowest average minimum soil temperature of 31°F occurred in January. The extreme minimum average soil temperature of 23°F occurred in January (Table 18).

          Maximum

          The 2023 maximum soil temperature average of 92°F occurred in July. The 23-year (2001–2023) monthly average maximum of 94°F also occurred in July (Table 19). The extreme maximum soil temperature of 106°F occurred in July 2005 (Table 20).

          Minimum

          The 2023 average minimum soil temperature of 32°F occurred in January. The 23-year (2001–2023) monthly average minimum soil temperature of 29°F also occurred in January (Table 21). The extreme minimum soil temperature of 9°F occurred in January 2013 (Table 22).
