Regional context
Garden City's climate, per the NOAA NCEI 1991-2020 normals from the nearest reporting station, runs cold-winter and warm-summer. January means hover near 25°F while July climbs to 73°F — a 48°F seasonal swing typical of northern-tier latitudes. Annual precipitation totals about 35.1 inches spread across roughly 78 days with measurable rain or snow.
Rainfall stays relatively even across the calendar: May tops out at 3.6 inches across 7.5 days with measurable rain, and February settles around 2.3 inches across 5.7 rainy days — a comparatively narrow seasonal range. That even-rainfall rhythm puts Garden City alongside places like Westland, MI, Inkster, MI and Dearborn Heights, MI — places without a single dominant storm season, where moisture arrives steadily across the calendar.
The frost-sensitive growing window opens around late-May, when overnight lows reliably clear freezing for cool-season crops like kale, peas, spinach, and parsnips. Heat-loving transplants like tomatoes, peppers, and squash generally hold off for another 10-14 days to clear the last spring frost risk window. The window closes around early-October, 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 Garden City, 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.
