What a year in Huron feels like
Typical highs and lows by season and by month, from NOAA’s 30-year normals.
About 209 frost-free days a year
In half of years the last 32° night comes by April 10 and the first by November 5. Frost and day counts come from NOAA’s station at Sandusky, OH, 9 miles from the town’s center, at about the same height.
The 2023 USDA map puts Huron’s center in zone 6b: the coldest night of a typical winter, averaged over 1991–2020, reaches about −2°. Plant labels use the zone; frost dates tell you when to plant.

Heating and cooling a home in Huron
86% of the work is heating, so the furnace matters far more than the air conditioner. Months averaging under 55° run from October through April.
Degree days add up how far each day’s average falls below (heating) or rises above (cooling) 65° over a year. NOAA normals at Sandusky, OH.
Living with Huron’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
209 frost-free days in zone 6b. The last frost comes by Apr 10 in half of years, so many gardeners wait a week or two past that to set out tomatoes. The first fall frost comes by Nov 5.
Months with highs of 62–84° and lows of 40° or more: May, June, July, August, September and October. 0.3 miles of trails are waiting.

| Huron, OH | 22° | 82° | 37" | 33" |
| Evanston, IL | 19° | 82° | 38" | 34" |

Temperatures and rain come from NOAA’s 5 km grid, so each town gets its own value. Snow and frost-free days come from the nearest weather station, so neighbors often share them.
Warmer than it used to be
The last 30 years in Huron averaged 0.9° warmer than the 1900s. The biggest change is in December (+2.3°).
A smaller shift than in 83% of U.S. towns.
Change by month
The two periods overlap (1991–2000 is in both), which makes the gap a little smaller than it would be between separate periods.
How Huron compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Huron’s place among Ohio’s.
