When is the best weather to visit Silverton?

Normal highs sit between 65°F and 85°F in April, May, September and October. Of those, April 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.

The USDA's 2023 Plant Hardiness Zone Map puts Silverton in zone 7b in ZIP code 79257, the nearest ZIP area. By the map's own method, the average of each year's coldest night over 1991-2020, Silverton's NOAA station is in zone 7a: the coldest night of a typical year reaches 4°F (30 complete years); the map interpolates between stations and terrain, so the station and the ZIP area can differ by half a zone.
