Alburtis, PA 18031 Frost Dates

When can you plant in Alburtis, PA?

Zone 7a

The last spring frost here typically falls around 04/20, about 235 days from today. The first fall frost typically arrives around 10/24, about 184 frost-free days later.

The USDA Plant Hardiness Zone Map puts Alburtis in Zone 7a (0 to 5°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

What to do before the first frost

About 8 weeks of growing season left in Alburtis before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 04/20 isn't a guarantee

04/20 is the middle of 30 years of NOAA records, not a promise. Plant by 04/06 and you're betting against frost in roughly 9 years out of 10. 05/06 is the safer bet, historically only a 1-in-10 chance of frost that late.
