Regional context
Corriganville's baseline climate, derived from NOAA NCEI 1991-2020 normals at the nearest reporting station, swings from a January mean of 31°F to a July mean of 76°F — a 45°F seasonal arc typical of the mid-latitude bands. Annual precipitation runs about 39.2 inches spread across roughly 79 days with measurable rain or snow each year.
Rainfall stays relatively even across the calendar: May tops out at 4.2 inches across 8.6 days with measurable rain, and February settles around 2.4 inches across 5.5 rainy days — a comparatively narrow seasonal range. That even-rainfall rhythm puts Corriganville alongside places like Ellerslie, MD, Bowmans Addition, MD and Barrelville, MD — places without a single dominant storm season, where moisture arrives steadily across the calendar.
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. Heat-loving transplants like tomatoes, peppers, and squash generally hold off for another 10-14 days to clear the last spring frost risk window. 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 Corriganville 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.
