Anyone planning to live, garden, or travel in Omak should weigh precipitation alongside temperature: the annual average runs 11.6 inches, predominantly as rainfall. The frost-free season averages 160 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near April 30 and the first fall freeze near October 7. And on the energy front, 6,177 heating degree days and 703 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Omak 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.
