🌡 The weather here, in general

Fort Collins gets a real winter. January nights average 16°F, and July highs reach about 87°F — a 71-degree swing across the year. Cold that deep is its own hazard: exposed skin, car batteries and water pipes all have opinions about it.

The thermometer rarely spikes — only about 24 days a year top 90°F — but it hardly needs to. Summer sits in the mid-eighties for months at a stretch, and with humidity on top of it the heat index runs well above what the air temperature suggests.

Snow is a real feature of the year: roughly 33 inches falls in an average year, mostly across January, February, March, April, November and December. With 150 nights a year at or below freezing, ice on the roads is a longer season than snow on the ground.

Rainfall averages about 16 inches a year, wettest in May and driest in January.
