When is the best weather to visit Experiment?
Normal highs sit between 65°F and 85°F in March, April, May, September, October and November. Of those, October has the fewest days with rain (8).
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 Experiment?
In Experiment, the last spring frost (32°F) comes after March 20 in half of years and after April 10 in one year in ten; the first autumn frost comes before November 13 in half of years and before October 31 in one year in ten.

Which places near Experiment share this climate record?
9 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.

Does it snow in Experiment?
Rarely. NOAA publishes no 1991-2020 snowfall normal for Experiment's NOAA station; the nearest record that keeps one, Jonesboro (19 miles away), records 1 inches of snow in a normal year.
What is the rainiest month in Experiment?
January, with 5.27 in of precipitation in a normal year; the driest is October with 3.31 in.
What plant hardiness zone is Experiment in?
The USDA's 2023 map puts Experiment in zone 8a in ZIP code 30223, the nearest ZIP area.
How late can frost come in Experiment?
In half of years the last 32°F night comes after March 20; in one year in ten it comes after April 10. Waiting until April 10 leaves about a one-in-ten chance of a later frost.
