Lyman sits in USDA Zone 8a (10 to 15°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.
What to do before the first frost
Zone 8a around Lyman has about 10 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 03/28 isn't a guarantee
03/28 is the middle of 30 years of NOAA records, not a promise. Plant by 03/10 and you're betting against frost in roughly 9 years out of 10. 04/14 is the safer bet, historically only a 1-in-10 chance of frost that late.
