Frost risk through the year
How sure are these dates?
A frost date is a probability, not a promise. NOAA worked out, from 30 years of nightly lows, how often the last spring frost and the first fall frost fall on each date. The middle column is the typical year. The outer columns are the early and late years that come about once a decade.
| Early year 1 in 10 | Typical year 1 in 2 | Late year 1 in 10 | |
|---|---|---|---|
| Last frost in spring | April 10 | April 24 | May 9 |
| First frost in fall | October 12 | October 28 | November 8 |
The frost-free season between them runs 186 days in a typical year. In 1 year in 10 it is 206 days or longer, and in 1 year in 10 it is 167 days or shorter.
- Hard freeze (28°F): typically last on April 13 and first on November 7. It is a harder freeze than the 32°F frost line, cold enough to damage many garden plants; how hardy a crop is decides whether it comes through. (The National Weather Service's own hard-freeze threshold varies from office to office.)
- Frost possible (36°F at the station): typically last on May 3 and first on October 15. On clear, still nights the ground can be several degrees colder than the thermometer, so frost can form on plants when the official reading is in the mid-30s.
In 8 springs out of 10, the last frost in Akron comes between April 10 and May 9, a window of 29 days. That is about average for NOAA's stations (the typical window is 31 days).
Among Ohio's 130 NOAA stations with a frost every year, 43 percent have their typical last frost later than Akron does.

Want more insurance? Shift every spring date 15 days later. That plans around May 9, the date after which only 1 spring in 10 has a frost.
For spring bulbs such as tulips and daffodils, plant once the soil has cooled to about 50 to 55°F and keep going until a couple of weeks before the ground freezes. Our guide to fall planting explains how to tell.
Where these numbers come from
These dates come from NOAA's weather station Akron Fulton International Airport (station USW00014813), 4 miles from the center of Akron. It sits at about the same elevation, 1,040 feet above sea level. NOAA rates this station's record as representative: at least 10 of the 30 years, with the gaps filled from nearby stations.
The same station also gives the frost dates for Cuyahoga Falls, Stow, Kent, Barberton, Solon, Hudson, Twinsburg and Tallmadge.
Our ZIP code lookup matches these 37 ZIP codes to the same station, so they get the same dates: 44056, 44067, 44087, 44203, 44216, 44221, 44223, 44224, 44236, 44240, 44241, 44243, 44250, 44260, 44262, 44264, 44278, 44286, 44301, 44302, 44303, 44304, 44305, 44306, 44307, 44308, 44310, 44311, 44312, 44313, 44314, 44319, 44320, 44321, 44325, 44333, 44614.
