NOAA publishes no 1991-2020 snowfall normal for this station. The nearest record that keeps one, Angola (20 miles away), gets 39 inches of snow in a normal year; elevation and distance can change that.

When is the best weather to visit Lagrange?
Normal highs sit between 65°F and 85°F in May, June, July, August and September. Of those, September has the fewest days with rain (9).
That is a measurement, not a recommendation: it counts the months whose normal afternoon high sits between 65°F and 85°F, where a light layer is enough by day.

When is the last frost in Lagrange?
In Lagrange, the last spring frost (32°F) comes after April 26 in half of years and after May 14 in one year in ten; the first autumn frost comes before October 21 in half of years and before October 5 in one year in ten.

- Last spring frost, half of years after
- April 261 year in 10 after May 14; 9 in 10 after April 13
- First autumn frost, half of years before
- October 211 year in 10 before October 5; 9 in 10 before November 2
NOAA puts the median frost-free season at 176 days, and the season without a hard freeze (28°F) at 200 days.
A hard freeze (28°F) comes after April 16 in half of springs and before November 1 in half of autumns.
The USDA's 2023 Plant Hardiness Zone Map puts Lagrange in zone 6a in ZIP code 46761, the nearest ZIP area.

How sunny is Lagrange?
Over a year 71% of the sunlight that would reach the ground under clear skies gets through the clouds in the area around Lagrange, 3.8 kWh per square metre a day. July is the sunniest month (81%) and December the cloudiest (55%).

How much heating and cooling does Lagrange need?
A normal year in Lagrange brings 6,427 heating degree days, 20% more than the median U.S. place (5,373), and 731 cooling degree days, 19% fewer than the median (908). Seven months need 300 or more heating degree days, a monthly mean of about 55°F or colder. For gardens and crops, NOAA counts 2,935 growing degree days a year above 50°F.

How does Lagrange's climate compare?
Lagrange is warmer than 2 of the other 98 places with their own NOAA record in Indiana, and wetter than 5. Across the 7,247 U.S. stations with normals, its annual mean of 49.3°F is warmer than 37%.
In the Köppen classification computed from these normals, Lagrange is Dfa: continental, no dry season, hot summer. What the classes mean.

Which places near Lagrange share this climate record?
14 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.

Questions about Lagrange's climate
What is the coldest month in Lagrange?
January, with a normal high of 31°F and a normal low of 17°F. The warmest is July (83°F by day, 62°F at night).
Does it snow in Lagrange?
Yes. NOAA publishes no 1991-2020 snowfall normal for Lagrange's NOAA station; the nearest record that keeps one, Angola (20 miles away), records 39 inches of snow in a normal year.
What is the rainiest month in Lagrange?
May, with 4.27 in of precipitation in a normal year; the driest is February with 1.91 in.
What plant hardiness zone is Lagrange in?
The USDA's 2023 map puts Lagrange in zone 6a in ZIP code 46761, the nearest ZIP area.
How late can frost come in Lagrange?
In half of years the last 32°F night comes after April 26; in one year in ten it comes after May 14. Waiting until May 14 leaves about a one-in-ten chance of a later frost.
