Climate Insight: Georgetown, CO

Based on station USC00053261 feeding NOAA's 1991–2020 climate normals, Georgetown, Colorado averages 42°F a year, ranging from a mean daily high of 55°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.

Rainfall (and snow, where it falls) shapes day-to-day life here as much as temperature does. Georgetown sees about 18.3 inches of precipitation a year, with 105.9 inches typically falling as snow. The frost-free season averages 112 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near May 30 and the first fall freeze near September 19. On the energy side, 8,312 heating degree days and 41 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Georgetown scores 34/100 (Below Average), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. For planning purposes, look to the monthly tables above: shoulder seasons bring the mildest highs and lows, summer brings July-driven heat, and deep winter brings January-driven cold. Treat every figure here as a thirty-year average rather than a forecast - individual years routinely run warmer, cooler, wetter, or drier than the normal.
