Colorado's Average Final Spring Freeze

A community's final freeze and frost of the season has much to do with the area's elevation. Lower elevations in Eastern and Western Colorado will see the final freeze of the season during April.

Higher elevations can take an additional six weeks before the final freeze of the season occurs. Areas like Grand Junction, Delta, and Montrose will see the final freeze of the year around April 20th. On the Front Range, Denver and Colorado Springs usually see the final freeze of the season the first week of May.

Colorado's Average Final Spring Frost

Frost is predicted when air temperature dips to 32°F. The final frost of the season occurs first in Colorado's lowest elevations by early May. Higher elevations in the San Juan Mountains will take until June before seeing their final frost, with the highest portions of the Rocky Mountains taking until July before a final frost date comes around.
