Regional context
Boring's climate, per the NOAA NCEI 1991-2020 normals from the nearest reporting station, runs cold-winter and warm-summer. January means hover near 40°F while July climbs to 68°F — a 28°F seasonal swing typical of northern-tier latitudes. Annual precipitation totals about 48.4 inches spread across roughly 161 days with measurable rain or snow.
Precipitation peaks in the cool season: November averages 7.5 inches across 25.0 days with measurable rain, mostly from frontal systems and winter storms, while July bottoms out at 0.6 inches across just 2.0 rainy days during the drier warm-season stretch. That winter-storm-driven distribution puts Boring alongside places like Orient, OR, Damascus, OR and Sandy, OR, all of which run drier through the summer months and rely on cool-season frontal activity for the year's precipitation.
The frost-sensitive growing window opens around late-May, 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 early-October, 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 Boring 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.
