Denver hail map & storm history
The Colorado Front Range is the statistical heart of Hail Alley — the corridor from Colorado Springs through Denver to Cheyenne sees more large-hail days than anywhere else in North America. High terrain keeps storm bases cold enough that hailstones survive the fall almost every time a storm fires.
Denver’s benchmark is the May 8, 2017 storm: baseball-sized hail across the west metro that produced more than $2.2 billion in insured losses — the costliest hailstorm in Colorado history. Events at some scale, though, are close to an annual guarantee here.

The Denver metro hailstorm
Baseball-sized hail tracked across Lakewood, Wheat Ridge, and the west metro, shattering windshields and skylights and generating more than $2.2 billion in insured losses — the costliest hail event in Colorado history.
Most summers
Front Range repeat swaths
Unlike Texas’s rare-but-massive pattern, the Front Range takes multiple damaging swaths in a normal season — which is why Colorado routinely ranks among the top states for hail claims and why hail deductibles keep rising on Colorado policies.
Working the Denver hail market
Denver is a repeat-swath market: the same suburbs take hail every few seasons, homeowners are claim-literate, and carriers scrutinize date-of-loss closely because overlapping storms muddy causation. Verified storm data isn’t a nice-to-have here — it’s how claims survive.
Crews that log every knock against a NOAA-verified swath, photograph soft-metal strikes, and cite the exact event date in the claim file close the causation argument before the adjuster raises it.
Frequently asked questions
Later than Texas: mid-May through July is the Front Range core season, driven by high-based summer storms coming off the foothills. June is historically the most active month for damaging hail in the Denver metro.
