Which months are mildest at Ola?
Normal highs sit between 65°F and 85°F in May, June, September and October. Of those, September has the fewest days with rain (4).
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.

NOAA puts the median frost-free season at 108 days, and the season without a hard freeze (28°F) at 142 days.
A hard freeze (28°F) comes after May 7 in half of springs and before September 29 in half of autumns.
The USDA's 2023 Plant Hardiness Zone Map puts Ola in zone 7a in ZIP code 83657, the nearest ZIP area. By the map's own method, the average of each year's coldest night over 1991-2020, the station is in zone 6a: the coldest night of a typical year reaches −5°F (19 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 Ola share this climate record?
Smiths Ferry has no NOAA station with 1991-2020 normals of its 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.
