Regional context
Richland's baseline climate, derived from NOAA NCEI 1991-2020 normals at the nearest reporting station, swings from a January mean of 33°F to a July mean of 78°F — a 45°F seasonal arc typical of the mid-latitude bands. Annual precipitation runs about 47.5 inches spread across roughly 72 days with measurable rain or snow each year.
Precipitation runs summer-dominant here: May averages 5.2 inches across 8.6 days with measurable rain, driven mostly by warm-season storms and thunderstorm activity, while January drops to just 2.7 inches across 4.1 rainy days under drier cool-season air. That wet-warm-summer pattern groups Richland with places like Stoutland, MO, Crocker, MO and Waynesville, MO — 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 peas, lettuce, spinach, and radishes. 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. Those dates are 30-year averages; the actual frost-free window in a given year can vary by 10-14 days at either end. Neighborhood-scale variation in elevation and cold-air pooling means the practical last-frost date inside Richland can lag the regional mean by 5-10 days in low spots, and a bench position with good cold-air drainage can run a week ahead.
