Zone 8a (10 to 15°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 Montross, not a forecast for this year.
What to do before the first frost
About 9 weeks of growing season left in Montross before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 04/08 isn't a guarantee
04/08 is the middle of 30 years of NOAA records, not a promise. Plant by 03/26 and you're betting against frost in roughly 9 years out of 10. 04/23 is the safer bet, historically only a 1-in-10 chance of frost that late.
