Regional context
Jamaica's climate, per the NOAA NCEI 1991-2020 normals from the nearest reporting station, runs cold-winter and warm-summer. January means hover near 17°F while July climbs to 66°F — a 48°F seasonal swing typical of northern-tier latitudes. Annual precipitation totals about 51 inches spread across roughly 170 days with measurable rain or snow.
Rainfall stays relatively even across the calendar: October tops out at 5.2 inches across 17.0 days with measurable rain, and February settles around 3.4 inches across 11.0 rainy days — a comparatively narrow seasonal range. That even-rainfall rhythm puts Jamaica alongside places like Wardsboro, VT, Stratton Mountain, VT and Townshend, VT — places without a single dominant storm season, where moisture arrives steadily across the calendar.
The frost-sensitive growing window opens around late-May, when overnight lows reliably clear freezing for cool-season crops like kale, peas, spinach, and parsnips. 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 early-October, 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 Jamaica 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.
