Summer freezes?
from Rutgers weather station
Summer freezes are uncommon but not unprecedented at some NJ locations. Today marks the second consecutive day with low temperatures at or below freezing at several Rutgers NJ Weather Network stations. Yesterday, September 19, Walpack (Sussex County) fell to 29°, with Sandyston (Sussex) and Pequest (Warren) both down to 31°. This morning, Walpack bottomed out at 31°, with Pequest and Basking Ridge (Somerset) each at 32°.
Walpack was last down to freezing on June 1, leaving this cold-air drainage prone valley site in northwest Jersey with a short 109 day growing season (days between last spring and first fall freeze). Meanwhile, several coastal stations had their last freeze on March 1, thus have had a 203 day growing season....and counting.
