When is the last frost in Toledo?
In Toledo, the last spring frost (32°F) comes after April 22 in half of years and after May 7 in one year in ten; the first autumn frost comes before October 24 in half of years and before October 11 in one year in ten.
Frost-free in half of yearsFrost in 1 to 9 years out of 10Frost most years
- Last spring frost, half of years after
- April 221 year in 10 after May 7; 9 in 10 after April 6
- First autumn frost, half of years before
- October 241 year in 10 before October 11; 9 in 10 before November 8
NOAA puts the median frost-free season at 188 days, and the season without a hard freeze (28°F) at 210 days.
A hard freeze (28°F) comes after April 8 in half of springs and before November 4 in half of autumns.
The USDA's 2023 Plant Hardiness Zone Map puts Toledo in zone 6b across its 14 ZIP code areas (6b in 43612, the largest). By the map's own method, the average of each year's coldest night over 1991-2020, Toledo's NOAA station is in zone 6a: the coldest night of a typical year reaches −5°F (30 complete years); the map interpolates between stations and terrain, so the station and the ZIP area can differ by half a zone.

Which places near Toledo share this climate record?
10 places have no NOAA station with 1991-2020 normals of their own, and this station is the nearest full record. A place's own climate can differ from these figures, by several degrees where it sits much higher or lower than the station, nearer the coast, or inside a large city's heat; for the larger places the next nearest records are named with their yearly mean, so the spread around them is visible, and places of 50,000 or more have their own page with NOAA's gridded normals.
