An annual average temperature of 48°F, ranging from a mean daily high of 61°F to a mean daily low of 35°F is what the NOAA 1991–2020 climate normals report for Halfway, Oregon. July is typically the warmest month of the year, while January is the coldest. That baseline comes from station USC00353604 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.
Anyone planning to live, garden, or travel in Halfway should weigh precipitation alongside temperature: the annual average runs 21.3 inches, with 62.3 inches typically falling as snow. The frost-free season averages 132 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near May 15 and the first fall freeze near September 24. And on the energy front, 6,656 heating degree days and 450 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Halfway scores 54/100 (Moderate), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. Use the monthly tables above to plan around specific windows, shoulder seasons for mild highs and lows, peak summer for July-driven heat, or deep winter for January-driven cold. All figures here are thirty-year averages: any single year may run warmer, wetter, drier, or cooler than the normal, so treat them as planning guidance rather than forecasts.
