Climate Insight: Loma, MT
Based on station USC00245153 feeding NOAA's 1991–2020 climate normals, Loma, Montana averages 45°F a year, ranging from a mean daily high of 60°F to a mean daily low of 30°F. July is typically the warmest month of the year, while January 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.
Anyone planning to live, garden, or travel in Loma should weigh precipitation alongside temperature: the annual average runs 12.8 inches, with 36.3 inches typically falling as snow. The frost-free season averages 122 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near May 20 and the first fall freeze near September 19. And on the energy front, 7,741 heating degree days and 413 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Loma scores 39/100 (Below Average), 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 July-driven heat, and winter brings January-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.
