Regional context
Vernon's baseline climate, derived from NOAA NCEI 1991-2020 normals at the nearest reporting station, swings from a January mean of 42°F to a July mean of 85°F — a 43°F seasonal arc typical of the mid-latitude bands. Annual precipitation runs about 28.4 inches spread across roughly 41 days with measurable rain or snow each year.
Precipitation runs summer-dominant here: June averages 4.1 inches across 5.3 days with measurable rain, driven mostly by warm-season storms and thunderstorm activity, while January drops to just 1.1 inches across 2.2 rainy days under drier cool-season air. That wet-warm-summer pattern groups Vernon with places like Lockett, TX, Oklaunion, TX and Chillicothe, TX — a regional cohort where summer thunderstorm season carries more than half the annual moisture.
The frost-sensitive growing window opens around mid-March, 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-December, 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 Vernon 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.
