What Eugene Mahlon Sweet's climate means for you
Eugene Mahlon Sweet runs 53°F a year - peaking in August, coldest in December.
These are 30-year NOAA normals (1991–2020) - the typical year, not a forecast for any specific season.
Based on station USW00024221 feeding NOAA's 1991–2020 climate normals, Eugene Mahlon Sweet, Oregon averages 53°F a year, ranging from a mean daily high of 64°F to a mean daily low of 42°F. August is typically the warmest month of the year, while December is the coldest. Because these figures are thirty-year averages rather than any single year's readings, they describe the typical month, not a forecast for it.
Eugene Mahlon Sweet averages 40.8 inches of precipitation a year, predominantly as rainfall, and that matters as much to daily life here as temperature does. The frost-free season averages 195 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near April 11 and the first fall freeze near October 23. As for energy demand, 4,616 heating degree days and 293 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Eugene Mahlon Sweet scores 68/100 (Good), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. Shoulder seasons bring the mildest highs and lows in the monthly tables above, summer brings August-driven heat, and winter brings December-driven cold - use that rhythm for planning. These figures are thirty-year averages rather than forecasts, so a specific year may still run warmer, cooler, wetter, or drier than what's shown.
