The widest day

September 26 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

How Oregon's climate pattern fits together

heating led · mid swing

Oregon's energy balance leans toward cold weather: 5,662 annual heating degree days against 1,208 for cooling. Its 51.6°F seasonal range still makes the monthly rows more useful than the annual average alone.

Oregon's frost-free season lasts about 187 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.

July and January mark the typical warm and cold ends of the calendar in Oregon's middle-range seasonal profile. The measured spread is 51.6°F. The annual average is 53°F. Neither the annual mean nor one extreme month represents the full calendar on its own.

A moisture-range label is withheld because Oregon'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 Oregon'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 Oregon, not an official NOAA class or a year-ahead forecast.

Questions about Oregon's climate

How many days above 90°F does Oregon get?
Oregon averages about 31 days a year at or above 90°F, concentrated in July and the months either side of it. That is a count of days reaching the threshold, not a measure of how far above it they go.
How much energy does heating and cooling require in Oregon?
Oregon has 5,662 heating degree days and 1,208 cooling degree days annually, a heating-dominated climate. Degree-day definitions: reading weather data.

Data Sources

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Oregon's primary station: OREGON (USC00236357). 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 2954848). Match rule for Oregon: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
