Regional context
Worland's climate, per the NOAA NCEI 1991-2020 normals from the nearest reporting station, runs cold-winter and warm-summer. January means hover near 17°F while July climbs to 74°F — a 57°F seasonal swing typical of northern-tier latitudes. Annual precipitation totals about 8.6 inches spread across roughly 25 days with measurable rain or snow.
Precipitation runs summer-dominant here: May averages 1.8 inches across 4.7 days with measurable rain, driven mostly by warm-season storms and thunderstorm activity, while December drops to just 0.2 inches across 0.7 rainy days under drier cool-season air. That wet-warm-summer pattern groups Worland with places like Kirby, WY, Manderson, WY and Lucerne, WY — a regional cohort where summer thunderstorm season carries more than half the annual moisture.
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. Warm-season transplants — tomatoes, peppers, and basil — typically wait two weeks past that date to avoid late spring cold snaps. The window closes around early-October, when overnight lows resume dipping below freezing and frost-tender plants need protection or harvest. These dates represent 30-year central tendencies; actual year-to-year variation can shift either bookend by 7-14 days, and local microclimate features within Worland — cold-air drainage on calm clear nights, slope aspect, distance from any nearby lake or river — can push the practical frost window earlier or later than the regional average.
