Climate Insight: Fossil, OR
An annual average temperature of 47°F, ranging from a mean daily high of 61°F to a mean daily low of 34°F is what the NOAA 1991–2020 climate normals report for Fossil, Oregon. July is typically the warmest month of the year, while December is the coldest. That baseline comes from station USC00353038 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.
Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Fossil receives roughly 15.1 inches of precipitation each year, predominantly as rainfall. The frost-free season averages 103 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near June 3 and the first fall freeze near September 14. For energy use, 6,565 heating degree days and 174 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Fossil 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.
