Phoenix hit 103 degrees on March 26. Amarillo, Texas, saw temperatures 25 degrees above normal for three consecutive days. Across the contiguous United States, March 2026 was not just warm. It was the most extreme departure from normal temperatures ever recorded in any month, in any season, since federal record-keeping began in 1895.
The National Centers for Environmental Information, the federal agency that maintains the country’s official climate record, confirmed in early April 2026 that the national average temperature for March reached 50.85 degrees Fahrenheit. That is 9.35 degrees above the 20th-century mean, the first time any month has crossed the 9-degree anomaly threshold. The previous record, set during an unusually warm February in 2015, fell short of that mark by nearly a full degree.
“Climate change is kicking our butts,” Andrew Pershing, vice president for science at Climate Central, told the Associated Press.
Where the heat hit hardest
The desert Southwest bore the brunt. Quality-controlled station data from NOAA showed triple-digit readings at low-desert stations in Arizona and southeastern California, temperatures that would be noteworthy in May, let alone March. But the anomaly was not a regional story. States across the Great Plains, the Ohio Valley, and the Upper Midwest all posted temperatures well above their historical March averages, according to NCEI’s climate division data.
The consequences arrived fast. On April 7, 2026, the U.S. Drought Monitor, a joint effort of the University of Nebraska-Lincoln, the USDA, and NOAA, tied March’s combination of record warmth and below-normal precipitation directly to worsening drought across wide sections of the West and central Plains. Soil moisture plummeted. Reservoirs already strained by a dry winter lost ground they could not afford to give up. For ranchers managing cattle on parched grassland and wheat farmers watching topsoil blow, the numbers on a federal chart translated into immediate financial pressure.
What scientists know and what they don’t yet
The temperature record itself is about as solid as climate data gets. NCEI’s national average draws on thousands of weather stations, satellite observations, and adjustment protocols refined over more than a century. The 50.85-degree figure and the 9.35-degree anomaly can be treated as established facts.
What has not yet been completed is a formal attribution study, the type of rapid scientific analysis that calculates precisely how much more likely human-caused warming made a specific event. Climate Central and academic groups routinely produce these assessments, but they typically take weeks to months. As of late April 2026, no peer-reviewed attribution analysis of March’s record has been published. Pershing’s comments reflect the broad scientific understanding that long-term warming loads the dice for events like this, but the precise fingerprint has not been quantified for this particular month.
The meteorological setup also deserves context. A persistent high-pressure ridge parked over the western United States for much of March funneled warm air northward and suppressed precipitation, a pattern consistent with blocking events that climate research has linked to shifts in the jet stream. Whether the ridge’s unusual persistence was itself influenced by warming remains an open question, one the attribution studies may eventually address.
Economic damage estimates are similarly incomplete. The Drought Monitor documents conditions, not costs. Dollar figures for crop losses, livestock stress, and strained municipal water systems tend to surface later through USDA disaster declarations, insurance claims, and state reporting. Until that data arrives, the full financial toll on affected communities cannot be reliably stated.
What it means on the ground
For the roughly 60 million Americans living in counties flagged by the Drought Monitor’s April 7 assessment, the practical implications are already unfolding. Water utilities in parts of Colorado, Kansas, and New Mexico have begun issuing conservation advisories. Fire weather watches have become routine across the southern Plains. County extension offices in agricultural regions are fielding questions about emergency haying permits and livestock water access.
The NCEI Past Weather Tool allows residents to look up their own station’s historical record and see exactly how March 2026 compared to the long-term average. For many locations, the answer will be stark.
Federal data confirms the conditions are severe. What happens next depends on whether April and May bring relief, or whether the pattern that made March 2026 historic continues to hold.
