While early warmth is not unprecedented, federal climate monitoring agencies say broader environmental conditions across the western United States suggest 2026 may be developing under an unusual combination of factors capable of influencing agricultural production later this year.

Across southern New Mexico, signs of spring have arrived early.
Warm temperatures stretching through late February and into early March have triggered budding and early blooms across much of the Mesilla Valley, with trees emerging from winter dormancy weeks ahead of what many growers consider typical seasonal timing. While early warmth is not unprecedented, federal climate monitoring agencies say broader environmental conditions across the western United States suggest 2026 may be developing under an unusual combination of factors capable of influencing agricultural production later this year.
Individually, none of those conditions guarantees hardship. Together, however, they represent a convergence that growers and water managers closely watch in arid regions dependent on tightly timed water supplies.
Federal Warning Signs Across the West
According to the U.S. Department of Agriculture’s Natural Resources Conservation Service (NRCS), much of the mountainous western United States is currently experiencing a snow drought — a seasonal deficit in mountain snowpack caused by warmer and drier winter conditions.
In its Feb. 12 Water and Climate Update, NRCS reported that the agency’s SNOTEL monitoring network recorded the lowest snowpack levels at many western stations in at least 40 years, noting that mountain snowpack is “a crucial element for shaping spring and summer water supplies in the arid western U.S.”
A follow-up report issued Feb. 19 indicated that even after significant snowfall in portions of the West, snowpack in many regions remained well below seasonal norms, with numerous monitoring sites continuing to measure record or near-record deficits.
Snowpack functions as the primary natural reservoir feeding rivers throughout the Southwest, including the Rio Grande system that ultimately supplies irrigation districts in southern New Mexico. Federal reports do not project specific impacts for Doña Ana County, but they emphasize that seasonal snow accumulation plays a central role in determining downstream water availability later in the year.
A Fixed Irrigation Calendar
In Doña Ana County, agricultural irrigation depends largely on water stored upstream in Elephant Butte and Caballo reservoirs and released through the Elephant Butte Irrigation District (EBID) canal system.
Historically, releases from Caballo Reservoir begin in late May, with Rio Grande water typically reaching the Las Cruces area in early June before being distributed through local ditch systems.
Las Cruces Digest has no information indicating when irrigation releases will occur for the 2026 growing season, and irrigation authorities have not publicly announced a release schedule as of publication.
That uncertainty exists alongside a biological reality: crops do not wait for irrigation calendars.
The Front-End Risk: Early Growth and Early Water Demand
Deciduous trees such as pecans respond primarily to accumulated warmth rather than dates on a calendar. As temperatures rise, dormant trees resume metabolic activity, initiating bud swell, leaf emergence, and new shoot growth.
Guidance from New Mexico State University’s Cooperative Extension Service emphasizes that pecan orchards require adequate soil moisture as growth resumes and that irrigation scheduling is intended to prevent depletion of available water within the root zone.
When budding occurs earlier than normal, orchard water demand may begin weeks before surface irrigation water becomes available. Earlier growth does not automatically result in crop stress, but it can lengthen the period during which orchards rely on residual soil moisture or groundwater pumping to sustain developing trees.
For growers reliant primarily on ditch irrigation, that interval represents a familiar but delicate seasonal bridge between winter dormancy and summer water delivery.
The Back-End Risk: The “False Spring” Problem
Early warmth introduces a second, separate agricultural concern known in climatology as a false spring — a period in which sustained warm temperatures trigger plant development before the historical end of freeze risk.
Once buds open and tissues become active, trees lose much of the cold tolerance present during dormancy. Freezing temperatures that might have caused little damage earlier in winter can injure or kill emerging growth later in the season.
Historical data from the National Weather Service shows that freezing temperatures in the Las Cruces area have occurred well into spring in past years.
Las Cruces Digest has no information suggesting an imminent freeze event, nor has any forecast indicated one at this time. However, climatological records demonstrate that freeze risk does not disappear simply because warm weather arrives early.
Groundwater as the Pressure Valve
When surface irrigation water is unavailable, many agricultural operations rely on groundwater wells to bridge early-season demand.
Regional planning documents, including the City of Las Cruces’ long-range water plan, note that groundwater pumping from storage has increased in part due to shortages in surface water supplies. Studies of the Mesilla Basin aquifer system similarly document long-term water-level declines associated with sustained withdrawals.
Groundwater often functions as the agricultural system’s safety valve — allowing orchards to maintain production when surface deliveries lag seasonal demand. Increased reliance on pumping, however, places additional pressure on aquifer systems already identified as under long-term stress.
A Rare Alignment of Risks
Taken individually, early seasonal warmth, reduced western snowpack, groundwater dependence, or lingering freeze risk are not unusual features of agriculture in southern New Mexico.
What makes 2026 noteworthy is their simultaneous appearance.
Earlier budding may advance tree water demand. Snow drought conditions raise uncertainty about seasonal water supply across the broader Rio Grande system. Surface irrigation deliveries remain tied to reservoir operations, while freeze risk historically persists into spring even after warm periods.
Las Cruces Digest has no information regarding when water will be released from Elephant Butte or Caballo reservoirs, no indication of an approaching freeze event, and no reliable method to calculate how current climatological conditions may ultimately affect pecan production in Doña Ana County.
This report is intended solely to inform readers of a developing collection of environmental conditions that agricultural researchers recognize as potentially consequential when they occur at the same time.
Entering an Uncertain Season
Pecan production remains one of Doña Ana County’s defining agricultural industries, shaped each year by the delicate interaction of weather, water, and timing.
Whether the 2026 growing season ultimately proves challenging or routine may not be known until harvest months from now. For now, growers across southern New Mexico are entering the season under conditions few would describe as typical — or optimal.
