Climate Insight: Inyokern, CA

The NOAA 1991–2020 climate normals describe Inyokern, California as a location with an annual average temperature of 65°F, ranging from a mean daily high of 80°F to a mean daily low of 49°F. July is typically the warmest month of the year, while December is the coldest. These thirty-year averages, computed from station USC00044278, smooth out year-to-year variability and give a baseline expectation for typical conditions in any given month.

Anyone planning to live, garden, or travel in Inyokern should weigh precipitation alongside temperature: the annual average runs 4.3 inches, with negligible snowfall. The frost-free season averages 256 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near March 9 and the first fall freeze near November 20. And on the energy front, 2,431 heating degree days and 2,389 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Inyokern scores 77/100 (Good), 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.
