Between January and March 2026, the contiguous United States received less than 70% of its average precipitation, making it the driest opening quarter in more than 130 years of record-keeping. The previous record, set in 1910, had stood for over a century. NOAA’s National Centers for Environmental Information confirmed the milestone in its March 2026 national climate summary, noting that March alone ranked as the eighth-driest March on record, compounding an already severe deficit from January and February.
For farmers preparing to plant, ranchers watching stock ponds shrink, and water managers tracking reservoir levels, the timing could hardly be worse. Spring is when snowmelt and rainfall are supposed to recharge the systems that carry communities through summer. Instead, the country entered April with a 30-percentage-point hole in its water budget.
Where the numbers come from
The record rests on NClimGrid, a high-resolution monthly dataset that divides the contiguous states into a 5-by-5 kilometer grid and tracks temperature and precipitation back to 1895. Station observations from the Global Historical Climatology Network-Daily feed into the grid, which NOAA then rolls up through its NClimDiv divisional database to produce state, regional, and national totals.
To calculate percent-of-average precipitation, NOAA divides each grid cell’s monthly total by its 1991 to 2020 baseline average, a method documented on the agency’s Climate.gov data snapshots page. Rankings that compare 2026 to every year since 1895 use a longer 1901 to 2000 baseline for anomaly calculations, ensuring consistency across the full historical window.
A peer-reviewed methods paper published in the Journal of Applied Meteorology and Climatology details how NOAA refined its divisional time series through updated inputs, bias adjustments, and improved interpolation. That rigor matters because it means the 2026 record is being measured against a carefully reconstructed historical baseline, not a patchwork of older, less reliable station data.
What the deficit means on the ground
A single dry month can be absorbed. A record-dry quarter is a different problem. Soil moisture, snowpack, and reservoir storage all depend on cumulative precipitation, and three consecutive months of well-below-normal moisture leave little margin heading into the growing season.
Spring planting across the Midwest and Great Plains typically ramps up in April and May. Corn, soybeans, and wheat all need adequate soil moisture at seeding to germinate and establish root systems. The U.S. Department of Agriculture has not yet released a formal assessment tying crop conditions to the 2026 shortfall, but the physics are straightforward: seeds planted into dry soil face higher failure rates, and replanting burns time, money, and fuel.
Ranchers face a parallel squeeze. Pasture growth depends on spring rain, and when grass comes in thin, producers must either buy supplemental feed, reduce herd sizes, or move cattle earlier than planned. Stock ponds and small impoundments that rely on runoff rather than piped water are especially vulnerable after a quarter this dry.
Wildfire risk also escalates. Fuels that would normally be dampened by spring moisture are instead curing early, extending the window during which grasslands and forests can carry fire. Land managers and fire agencies use precipitation deficits as one input when pre-positioning crews and equipment, and a record-setting shortfall raises the baseline threat level before summer even begins.
Big gaps in the picture
NOAA’s March assessment confirms the national-scale record but does not yet break out which climate divisions or states bore the worst of the deficit. That regional detail matters enormously. A rancher in eastern Montana and a citrus grower in central Florida need to know whether the dryness was concentrated in the West, spread evenly across the Plains and Southeast, or driven by a few extremely dry pockets pulling the national average down. Until NOAA or state climatologist offices publish divisional breakdowns, the national figure is a blunt instrument.
Attribution is similarly unresolved. No official NOAA statement in the available reporting connects this quarter to long-term climate trends, and while NOAA’s Climate Prediction Center had been monitoring La Nina conditions earlier in the winter, no formal analysis has linked the precipitation deficit to a specific large-scale driver. Secondary news coverage has speculated about Pacific sea surface temperature anomalies and jet stream shifts, but those interpretations lack primary-source backing from the agency itself.
Forward-looking forecasts add another layer of uncertainty. NOAA’s Climate Prediction Center publishes monthly and seasonal outlooks, but as of late May 2026, no tailored projection has been released that directly addresses whether the second quarter will bring enough rain to offset the first-quarter deficit. Whether relief arrives or the drought deepens remains an open question.
Reservoir conditions vary widely by basin. In parts of the Colorado River system, storage had improved during wetter years earlier in the decade, providing some buffer. In heavily pumped groundwater basins across the southern High Plains, even one record-dry quarter can accelerate long-term depletion that took decades to develop. Without basin-by-basin accounting tied to the 2026 shortfall, those differences are hard to quantify.
How to track what happens next
National records describe an average across a vast area, and individual counties or watersheds may be wetter or drier than the CONUS figure suggests. Several tools can help readers translate the headline number into local reality:
- The U.S. Drought Monitor, updated weekly, maps drought intensity from abnormally dry (D0) through exceptional drought (D4) at the county level.
- State climatologist offices publish monthly summaries with regional precipitation rankings and soil moisture assessments.
- NOAA’s Climate Prediction Center posts 30-day and seasonal precipitation outlooks that can signal whether relief is likely.
- The USDA’s weekly Crop Progress reports, released during the growing season, track planting pace and crop condition ratings state by state.
Ranchers and irrigators should pair the national context with on-the-ground indicators: soil moisture probes, stock pond levels, and snowpack reports from nearby mountain basins. Municipal water managers can review reservoir storage trends and demand projections to gauge whether voluntary conservation measures will be enough or whether mandatory restrictions may follow later in the year.
An unprecedented start, with the hardest months ahead
The record-dry January through March period is established by long-running, quality-controlled datasets and peer-reviewed methods. What it will mean for specific communities, crops, and water systems over the coming months depends on local conditions and weather that has not yet arrived. As regional analyses, attribution studies, and agricultural assessments emerge through the spring and summer, they will add critical detail. But they will all rest on the same core finding: the contiguous United States has never started a year this dry in more than a century of measurement, and the consequences are only beginning to unfold.
