Which months are mildest at Transou?
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 (11).

NOAA puts the median frost-free season at 158 days, and the season without a hard freeze (28°F) at 182 days.
A hard freeze (28°F) comes after April 20 in half of springs and before October 20 in half of autumns.
The USDA's 2023 Plant Hardiness Zone Map puts Transou in zone 7a in ZIP code 28644, 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 6b: the coldest night of a typical year reaches 0°F (24 complete years); the map interpolates between stations and terrain, so the station and the ZIP area can differ by half a zone.
