Map of the contiguous United States showing the spring bloom index anomaly as of April 19, 2026 from the USA National Phenology Network. Many areas are earlier than normal.
Aside from Florida, nearly the entire contiguous U.S. has experienced earlier than average first plant blooms in 2026. Earlier springs can cause longer allergy seasons, accelerate wildfire risk, increase pests/mosquitoes, and lead to less reliable snow-fed water.
