Climate Insight: Martinsdale, MT

Based on station USC00245387 feeding NOAA's 1991–2020 climate normals, Martinsdale, Montana averages 44°F a year, ranging from a mean daily high of 58°F to a mean daily low of 30°F. July 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.

Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Martinsdale receives roughly 13.5 inches of precipitation each year, with 43.4 inches typically falling as snow. The frost-free season averages 97 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 8. For energy use, 7,878 heating degree days and 136 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Martinsdale scores 39/100 (Below Average), 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.
