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. A hard freeze of 28°F follows 12 days later, around November 9; in spring the one-in-ten date for 28°F is April 15, 15 days before the 32°F one. The freeze-free season lasts 196 days in a typical year, longer than at 55% of the 56 New Jersey stations; it reaches 216 days one year in ten and falls short of 175 one year in ten. On average 108 nights a year drop to 32°F or below. Nights of 36°F, when frost can still settle on leaves in low, open spots, continue 15 days longer, to about April 29, and return around October 16. Severe cold of 16°F or below comes every winter, usually between December 19 and February 28.
