Regional context

Per NOAA NCEI 1991-2020 normals, Lander runs from a 21°F January mean to 72°F in July, a 50°F seasonal spread, with near 13.2 inches of precipitation across about 33 wet days.

Precipitation in Lander runs summer-dominant: May averages 2.7 inches across 5.0 days of warm-season storms, while January drops to 0.5 inches over 1.8 rainy days of drier cool air. That summer-storm rhythm groups Lander with places like Boulder Flats, WY, Hudson, WY and Ethete, WY.

Once Lander passes late-May, overnight freezes fade and kale, peas, spinach, and parsnips can be sown. Heat-demanding starts go out a fortnight on in Lander, after the soil warms and cold snaps clear. Frost returns to Lander near early-October, ending the tender-crop season. Lander's low ground holds frost later into spring than Lander's benches, which run 3-5 days ahead.

Similar climates: Boulder Flats, WY, Hudson, WY, Ethete, WY, Fort Washakie, WY, Arapahoe, WY.
