Regional context
Quapaw'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 80°F — a 46°F seasonal arc typical of the mid-latitude bands. Annual precipitation runs about 46 inches spread across roughly 68 days with measurable rain or snow each year.
Precipitation runs summer-dominant here: May averages 7.1 inches across 8.6 days with measurable rain, driven mostly by warm-season storms and thunderstorm activity, while January drops to just 1.7 inches across 3.8 rainy days under drier cool-season air. That wet-warm-summer pattern groups Quapaw with places like Commerce, OK, North Miami, OK and Peoria, OK — 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. 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 Quapaw — 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.
