Regional context
Burns's baseline climate, derived from NOAA NCEI 1991-2020 normals at the nearest reporting station, swings from a January mean of 27°F to a July mean of 71°F — a 44°F seasonal arc typical of the mid-latitude bands. Annual precipitation runs about 15.3 inches spread across roughly 39 days with measurable rain or snow each year.
Precipitation runs summer-dominant here: May averages 2.4 inches across 5.7 days with measurable rain, driven mostly by warm-season storms and thunderstorm activity, while January drops to just 0.3 inches across 0.7 rainy days under drier cool-season air. That wet-warm-summer pattern groups Burns with places like Hillsdale, WY, Carpenter, WY and Pine Bluffs, WY — a regional cohort where summer thunderstorm season carries more than half the annual moisture.
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-season transplants — tomatoes, peppers, and basil — typically wait two weeks past that date to avoid late spring cold snaps. The window closes around mid-November, when overnight lows resume dipping below freezing and frost-tender plants need protection or harvest. These are 30-year central tendencies; year-to-year frost dates can move by up to two weeks. Local features matter: a south-facing slope inside Burns typically runs 3-5 days ahead of the regional last-frost date, while a low-lying lot along a creek or drainage can lag the same date by a week or more on calm clear nights.
