Frost risk by date in Panama

Half of springs at Chandlers Valley 1SE, PA see their last 32°F night by May 22; only one in ten is past it by May 6, and one in ten still has one after June 5. Planting tender crops after May 28 leaves a 30% risk of a frost on them, after May 31 20%, and after June 5 10%. The 14 days between the even-odds date and the one-in-ten date is narrower than at 63% of the 173 New York stations behind this site's ZIP pages.

In fall the first 32°F night comes by September 30 in half of years, as early as September 16 one year in ten, and holds off past October 12 one year in ten. A hard freeze of 28°F follows 11 days later, around October 11; in spring the one-in-ten date for 28°F is May 25, 11 days before the 32°F one. The freeze-free season lasts 131 days in a typical year, shorter than at 98% of the 173 New York stations; it reaches 152 days one year in ten and falls short of 109 one year in ten. On average 173 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 12 days longer, to about June 3, and return around September 18. Severe cold of 16°F or below comes every winter, usually between November 21 and April 1.
