Regional context
Santaquin's baseline climate, derived from NOAA NCEI 1991-2020 normals at the nearest reporting station, swings from a January mean of 29°F to a July mean of 76°F — a 48°F seasonal arc typical of the mid-latitude bands. Annual precipitation runs about 18.4 inches spread across roughly 46 days with measurable rain or snow each year.
Precipitation peaks in the cool season: April averages 2.2 inches across 5.6 days with measurable rain, mostly from frontal systems and winter storms, while July bottoms out at 0.7 inches across just 1.5 rainy days during the drier warm-season stretch. The pattern groups Santaquin with places like Spring Lake, UT, Rocky Ridge, UT and Genola, UT, places whose summer-dry rhythm and cool-season-wet recharge run on the same regional storm-track exposure.
The frost-sensitive growing window opens around mid-April, when overnight lows reliably clear freezing for cool-season crops like kale, peas, spinach, and parsnips. Warm-soil crops — tomatoes, peppers, eggplant — wait until soil temperatures reach the mid-50s°F, usually two weeks past the last-frost date. The window closes around mid-November, when overnight lows resume dipping below freezing and frost-tender plants need protection or harvest. The dates above are 1991-2020 normals; in a given year either bookend can move 1-2 weeks either direction. Within Santaquin, low-lying parcels along drainage features typically lose 4-7°F of overnight low temperature versus the bench positions on calm clear nights, which shifts the working last-frost date by a week or more.
