Maquoketa, IA: when does the frost end?

Zone 5a

The last spring frost here typically falls around 04/25, about 240 days from today. Fall's first freeze usually shows up around 10/14, roughly 171 days after the last spring frost.

Maquoketa sits in USDA Zone 5a (-20 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.

Stretching the season past the first frost

With roughly 7 weeks until Maquoketa's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

How much risk comes with planting early here

04/25 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/11 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/09 and only about 1 year in 10 sees frost after that.
