Moore, ID 83244 Frost Dates
When can you plant in Moore, ID?
Around 05/24 is the usual last spring frost, about 269 days away. The first fall frost typically arrives around 09/14, about 113 frost-free days later.
Zone 5a (-20 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 Moore, not a forecast for this year.
What to do before the first frost
About 2 weeks of growing season left in Moore before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 05/24 isn't a guarantee
05/24 is the middle of 30 years of NOAA records, not a promise. Plant by 05/06 and you're betting against frost in roughly 9 years out of 10. 06/14 is the safer bet, historically only a 1-in-10 chance of frost that late.
