Data-derived climate profile
How McMinnville's climate pattern fits together
heating led · low swing
Heating is the larger measured load in McMinnville, at 4,477 degree days versus 366 for cooling. Unlike a strongly continental record, however, its 28.3°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
McMinnville's frost-free season lasts about 216 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
Temperature varies within a narrow 28.3°F band across the normal year. July and December mark the typical warm and cold ends of the calendar. The annual average is 54°F. Monthly rows still matter, but they refine a steady profile rather than reveal two climatic extremes.
A moisture-range label is withheld because McMinnville's annual precipitation total is unavailable. Monthly source values remain visible where NOAA provides them, and no annual amount is reconstructed from incomplete data.
These labels group NOAA 1991-2020 normals from McMinnville's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for McMinnville, not an official NOAA class or a year-ahead forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from McMinnville's primary station: MC MINNVILLE (USC00355384). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The 2024 Census Gazetteer identifies the exact name-and-state match as an incorporated place (GEOID 4145000). Match rule for McMinnville: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
On this page every temperature, precipitation, and derived score for McMinnville comes from its primary NOAA station record.
