Hillview, IL 62050 Frost Dates
When can you plant in Hillview, IL?
Around 04/13 is the usual last spring frost, about 228 days away. The first fall frost typically arrives around 10/22, about 190 frost-free days later.
The USDA Plant Hardiness Zone Map puts Hillview in Zone 6b (-5 to 0°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 Hillview before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 04/13 isn't a guarantee
04/13 is the middle of 30 years of NOAA records, not a promise. Plant by 03/30 and you're betting against frost in roughly 9 years out of 10. 04/28 is the safer bet, historically only a 1-in-10 chance of frost that late.
