The United States is facing an early and severe allergy season in 2026, characterized by spring allergies that start earlier and last longer than usual. Regions across the Southeast, Southwest, Northeast, and Pacific Northwest are already reporting allergy symptoms. Dr. Purvi Parikh, a New York City-based allergist, notes that despite a recent blizzard, warmer temperatures are contributing to the early onset of the allergy season. This trend aligns with previous years, where rising temperatures have intensified allergy seasons.
