Nationwide drought coverage surged from 49% to nearly 100% in one year, with exceptional-category drought doubling and extreme drought tripling.

From May 2025 through July 2025, drought coverage held steady near 45-47%. Starting in August, coverage began climbing sharply, accelerating through fall and winter to peak at 106% in May 2026 — exceeding normal geographic bounds and indicating severe spatial concentration. Extreme (D3) and exceptional (D4) categories followed the same explosive trajectory, rising from under 2% combined to over 18% by spring 2026.

If this trend persists, the US faces a sustained multi-year drought event of unprecedented scope and intensity. The data suggests conditions will stabilize at elevated levels through 2026-2027 before any meaningful recovery, with exceptional drought becoming endemic rather than anomalous. Water availability, agricultural productivity, and hydroelectric generation will remain under severe stress across broad regions simultaneously.

Agriculture, water utilities, and hydropower infrastructure face critical exposure, as simultaneous stress across 75-100% of the country eliminates geographic diversification and backup supply. Real estate values in water-scarce regions, food supply chains dependent on irrigated crops, and insurance portfolios carrying drought-linked liabilities all face material loss potential.
