What stands out about Aurora’s climate
Compared with towns across the U.S., with Aurora’s place in Ohio beside it.
What a year in Aurora feels like
Typical highs and lows by season and by month, from NOAA’s 30-year normals.
About 189 frost-free days a year
In half of years the last 32° night comes by April 21 and the first by October 29. Frost and day counts come from NOAA’s station at Ravenna 2 S, OH, 12 miles from the town’s center, at about the same height.
The 2023 USDA map puts Aurora’s center in zone 6a: the coldest night of a typical winter, averaged over 1991–2020, reaches about −6°. Plant labels use the zone; frost dates tell you when to plant.

Heating and cooling a home in Aurora
91% 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 Ravenna 2 S, OH.
Living with Aurora’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
189 frost-free days in zone 6a. The last frost comes by Apr 21 in half of years, so many gardeners wait a week or two past that to set out tomatoes. The first fall frost comes by Oct 29.
Months with highs of 62–84° and lows of 40° or more: May, June, July, August and September. 12 miles of trails are waiting.
Parks & trails →Of the yearly building losses FEMA expects in Aurora from natural hazards, river flooding is the largest share (67%); heat waves, cold waves, winter storms and ice storms together are 8%. Normals are averages; the hazards page covers the extremes.

Climates most like Aurora’s, farther away
TownRatings’ own comparison of NOAA 1991–2020 normals, not a NOAA product: places of 5,000+ at least 150 miles away, one per state, closest on January low, July high, precipitation and snow.
| Town | Jan. low | July high | Precip. | Snow |
|---|---|---|---|---|
| Aurora, OH | 19° | 82° | 42" | 45" |
| Park Forest Village, PA | 20° | 82° | 43" | 44" |
| Owego, NY | 16° | 82° | 40" | 49" |
| Portage, IN | 19° | 83° | 38" | 40" |
| Coldwater, MI | 17° | 83° | 39" | 43" |
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 Aurora averaged 1.8° warmer than the 1900s. The biggest change is in December (+3.3°).
A bigger shift than in 82% 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 Aurora compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Aurora’s place among Ohio’s.
