What Pendleton's climate means for you
Pendleton runs 52°F a year - peaking in July, coldest in December.
These are 30-year NOAA normals (1991–2020) - the typical year, not a forecast for any specific season.
In Pendleton, Oregon, the NOAA 1991–2020 climate normals put the annual average temperature at 52°F, ranging from a mean daily high of 64°F to a mean daily low of 41°F. July is typically the warmest month of the year, while December is the coldest. As thirty-year averages computed from 2 weather stations, these numbers smooth out year-to-year noise into a working baseline for a typical month.
Beyond temperature, Pendleton averages 12.8 inches of precipitation annually, with 15.7 inches typically falling as snow - a real factor for anyone planning to live, garden, or travel here. The frost-free season averages 173 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near April 26 and the first fall freeze near October 16. Turning to energy use, 5,340 heating degree days and 636 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Pendleton scores 54/100 (Moderate), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. The monthly tables above turn that into a planning tool: expect the mildest highs and lows in the shoulder seasons, July-driven heat at the peak of summer, and December-driven cold at the depth of winter. Every number here is a thirty-year average, not a forecast, so any given year can and does run warmer, cooler, wetter, or drier than the normal.
