9 March 2022 (National Phenology Network) – Spring leaf out continues to progress across the country. Our spring leaf anomaly compares the arrival of spring leaf out this year to a long-term average of 1991-2020. After a slow start to spring across much of the Southeast, spring is progressing more rapidly, arriving a few days to a week early in the southern Great Plains, the Southern Appalachians, and parts of Kentucky, Ohio, and West Virginia. The Washington, D.C. area is 5-10 days early. In western states, spring leaf out is patchy, arriving a week late in some locations and over a month early in others.

Spring bloom has also started to arrive in southern states, days to a week late in Texas and Florida and days to several weeks early in California. Spring bloom is over a week early in parts of Georgia and South Carolina.

We will continue to update this page as spring leaf out and bloom unfold across the country – check back frequently on this page!

How often do we see a spring this early or late?

In places where spring has sprung, how typical is this year’s spring? Darker colors represent springs that are unusually early or late in the long-term record. Gray indicates an average spring.

In parts of California and Arizona, this year’s spring leaf out is the earliest in the 40-year record (dark green).   

In parts of Texas, this year’s spring bloom is the latest on record (dark purple). [more]
