Regional context

Per NOAA NCEI 1991-2020 normals, Aurora runs from a 32°F January mean to 75°F in July, a 43°F seasonal spread, with near 15.4 inches of precipitation across about 38 wet days.

Precipitation in Aurora runs summer-dominant: May averages 2.3 inches across 5.2 days of warm-season storms, while January drops to 0.5 inches over 1.6 rainy days of drier cool air. It is a warm-season-wet pattern Aurora shares with places like Aetna Estates, CO, Watkins, CO and Denver, CO.

Around mid-April, Aurora sheds its freezing nights — peas, lettuce, spinach, and radishes go into Aurora's beds. Heat-demanding starts go out a fortnight on in Aurora, after the soil warms and cold snaps clear. By mid-November, frost is back in Aurora — protect or harvest anything tender. A creek-bottom lot in Aurora can lag Aurora's last frost 7-10 days behind a south slope.
