Regional context
Marydel's baseline climate, derived from NOAA NCEI 1991-2020 normals at the nearest reporting station, swings from a January mean of 36°F to a July mean of 78°F — a 42°F seasonal arc typical of the mid-latitude bands. Annual precipitation runs about 47.6 inches spread across roughly 74 days with measurable rain or snow each year.
Rainfall stays relatively even across the calendar: August tops out at 4.9 inches across 5.7 days with measurable rain, and February settles around 3.1 inches across 6.5 rainy days — a comparatively narrow seasonal range. The balanced distribution lines Marydel up with places like Templeville, MD, Henderson, MD and Goldsboro, MD, all of which run on overlapping storm tracks rather than a single seasonal moisture source.
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-soil crops — tomatoes, peppers, eggplant — wait until soil temperatures reach the mid-50s°F, usually two weeks past the last-frost date. 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 Marydel 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.
