Data-derived climate profile
How Beaverton's climate pattern fits together
heating led · low swing
Heating is the larger measured load in Beaverton, at 4,439 degree days versus 349 for cooling. Unlike a strongly continental record, however, its 27.6°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
Beaverton's frost-free season lasts about 219 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 27.6°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 Beaverton'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 Beaverton'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 Beaverton, not an official NOAA class or a year-ahead forecast.
