Zone 7b (5 to 10°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Hoboken, not a forecast for this year.
What to do before the first frost
Zone 7b around Hoboken has about 12 weeks left before the first fall frost — that's the usual window to get a cold frame up if you want to keep harvesting past it.
Why 03/30 isn't a guarantee
03/30 is the middle of 30 years of NOAA records, not a promise. Plant by 03/14 and you're betting against frost in roughly 9 years out of 10. 04/09 is the safer bet, historically only a 1-in-10 chance of frost that late.
