Climate & Weather in Fort Collins
Fort Collins has a cold semi-arid climate with real, large seasonal swings -- a genuinely different profile than the Arizona desert markets built earlier in this project, with no extreme sustained summer heat risk, but a real winter with average lows around 16°F in December and roughly 48 inches of snow a year, well above the U.S. average of 28 inches.

Learn moreA Real Four-Season, Semi-Arid Climate
Fort Collins's temperatures range from an average low of around 16°F in December to an average high around 87°F in July, per aggregated climate-data sources, with the broader annual range cited from 19°F to 87°F. This is a genuinely different profile than the sustained extreme summer heat of the Arizona desert markets covered elsewhere in this project -- Fort Collins's roughly 4,982-5,004-foot elevation and semi-arid Front Range geography keep summer heat real but not extreme, while producing a genuine winter that low-elevation desert cities don't share.
Snowfall: Real, Above the National Average
Fort Collins averages roughly 48 inches of snow per year, well above the U.S. average of 28 inches, with March cited as the snowiest month (around 3.27 inches). This is a real, seasonal factor for anyone relocating from a snow-free climate -- winter driving conditions and snow removal are a genuine part of life in Fort Collins in a way they are not in the Sun Belt or desert markets covered elsewhere in this project.
Sunny Days: A Real, if Source-Disputed, Number
Sources disagreed on Fort Collins's exact sunny-day count this session: one source cited about 237 sunny days per year, while another cited closer to 300, describing Fort Collins as exceeding both Miami's and Los Angeles's annual sunshine hours. Both figures describe the same general conclusion -- a genuinely sunny climate for a place with real winter snowfall -- but the roughly 60-day spread is disclosed here rather than picked arbitrarily.
Severe Thunderstorms and Hail Season
As detailed on the homeowners-insurance and flood-hurricane-risk topic pages, Fort Collins sits within Colorado's Front Range hail corridor, with real, documented hail risk during the region's spring-through-summer severe-thunderstorm season -- a genuine, independent seasonal hazard alongside winter snow and the wildfire-season risk covered on the flood-hurricane-risk topic page.
Not the Extreme-Heat Risk Profile of the Arizona Desert Markets
Fort Collins's July average high of around 87°F is a real but moderate summer peak, genuinely different from the sustained, extreme summer heat risk profile of the Arizona desert markets built earlier in this project -- this page deliberately does not carry over that extreme-heat framing. Fort Collins's real weather risks are winter snow/ice, spring-summer hail, and, in dry years, wildfire smoke and risk from the nearby foothills and mountains (see flood-hurricane-risk).
Key takeaways
- Fort Collins averages around 16°F (low) in December and around 87°F (high) in July -- a real four-season, semi-arid climate, genuinely different from the sustained extreme summer heat of Arizona desert markets built elsewhere in this project.
- Fort Collins averages roughly 48 inches of snow per year, well above the U.S. average of 28 inches -- a genuine winter-weather factor absent from Sun Belt and desert markets.
- Sunny-day counts disagreed by source (roughly 237 vs. 300 per year) -- both describe a genuinely sunny climate even alongside real winter snowfall.
- Spring-through-summer severe thunderstorms bring real, documented hail risk (Front Range Hail Alley), an independent seasonal hazard from winter snow and wildfire-season risk.
- This page deliberately does not carry over an extreme-heat framing from the Arizona desert markets built earlier in this project -- Fort Collins's real risks are winter snow/ice, hail, and wildfire, not sustained extreme heat.
