When is the best weather to visit Youngstown?

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 (10).

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.

May 11 year in 10 after May 20; 9 in 10 after April 16
First autumn frost, half of years before
October 171 year in 10 before October 1; 9 in 10 before November 1

NOAA puts the median frost-free season at 167 days, and the season without a hard freeze (28°F) at 194 days.

A hard freeze (28°F) comes after April 20 in half of springs and before November 1 in half of autumns.

The USDA's 2023 Plant Hardiness Zone Map puts Youngstown in zone 6a across its 9 ZIP code areas (6a in 44505, the largest). By the map's own method, the average of each year's coldest night over 1991-2020, Youngstown's NOAA station is in zone 6b: the coldest night of a typical year reaches −3°F (30 complete years); the map interpolates between stations and terrain, so the station and the ZIP area can differ by half a zone.

Which places near Youngstown share this climate record?

15 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.
