When is the best weather to visit Danville?

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.

The USDA's 2023 Plant Hardiness Zone Map puts Danville in zone 6a in ZIP code 43014, the nearest ZIP area. By the map's own method, the average of each year's coldest night over 1991-2020, Danville's NOAA station is in zone 5b: the coldest night of a typical year reaches −11°F (28 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 Danville share this climate record?

8 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.
