Frost risk by date in Lincoln Park
Half of springs at Caldwell Essex Co Airport, NJ see their last 32°F night by April 14; only one in ten is past it by April 1, and one in ten still has one after April 30. Planting tender crops after April 20 leaves a 30% risk of a frost on them, after April 23 20%, and after April 30 10%. The 16 days between the even-odds date and the one-in-ten date is narrower than at 38% of the 56 New Jersey stations behind this site's ZIP pages.
In fall the first 32°F night comes by October 28 in half of years, as early as October 13 one year in ten, and holds off past November 11 one year in ten.
