🏔️ Denver Weather

A mile high, where weather turns on a dime

Denver sits exactly a mile above sea level on the high plains at the foot of the Rockies, and that altitude and proximity to the mountains make its semi-arid climate famously changeable. The city enjoys roughly 300 days of sunshine a year, huge day-to-night temperature swings, and a knack for delivering dramatic weather reversals — 70°F (21°C) and sunny one afternoon, snowing the next morning.

Chinooks and sudden snow

Winters are paradoxically mild and sunny between storms, thanks to warm, dry "chinook" winds that spill down off the mountains and can erase a snowpack in hours. But powerful upslope storms can also bury the city, often in spring — March is actually Denver's snowiest month. January highs average a deceptively pleasant 45°F (7°C), with frigid nights.

Hail Alley summers

Summers are warm and dry, with July highs around 90°F (32°C) eased by low humidity and cool evenings. Denver sits in "Hail Alley," where afternoon thunderstorms rolling off the Front Range regularly pelt the metro with damaging hail — among the most hail-prone regions in North America.

Denver is genuinely dry, receiving only about 15 inches (380 mm) of precipitation a year. The thin, clear air intensifies the sun, so UV levels run high even on cold days, and shade can feel dramatically cooler than direct sunlight.

A mile high with Chinook winds

At exactly 5,280 feet (1,609 m), Denver's high-plains climate is dry, sunny, and prone to enormous daily swings — the thin air heats fast by day and cools sharply at night. Warm 'Chinook' winds spilling off the Rockies can melt snow and spike winter temperatures by 40°F (22°C) in hours.

The city sits in a semi-arid rain shadow east of the mountains, so it's far drier and sunnier than its snowy image suggests. But spring brings heavy, wet snowstorms and a real hail threat — the Front Range is one of the most hail-prone regions in North America — and blizzards can howl in off the plains.
