What a year in Darmstadt feels like
Typical highs and lows by season and by month, from NOAA’s 30-year normals.
About 206 frost-free days a year
In half of years the last 32° night comes by April 4 and the first by October 29. Frost and day counts come from NOAA’s station at Evansville Regional Airport, 4 miles from the town’s center, at about the same height.
The 2023 USDA map puts Darmstadt’s center in zone 7a: the coldest night of a typical winter, averaged over 1991–2020, reaches about 1°. Plant labels use the zone; frost dates tell you when to plant.

Living with Darmstadt’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
206 frost-free days in zone 7a. The last frost comes by Apr 4 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: April, May, September and October. 0.4 miles of trails are waiting.

| Town | Jan. low | July high | Precip. | Snow |
|---|---|---|---|---|
| Darmstadt, IN | 25° | 88° | 49" | 14" |
| Collegeville, PA | 23° | 88° | 47" | 13" |

| Paris, KY | 24° | 87° | 49" | 15" |
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 Darmstadt averaged 1.0° warmer than the 1900s. The biggest change is in December (+1.8°).
A smaller shift than in 80% 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 Darmstadt compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Darmstadt’s place among Indiana’s.
