The Denver Case · Sunshine & climate · Updated October 2026

Does Denver really get 300 days of sunshine?

Not quite. NOAA counts about 245 days a year in Denver that are clear or partly cloudy. That's still more sun than 9 of the other 12 metros get, and the heat that comes with it is dry.

Denver's main hazards are hail, lightning and wind. Hurricanes don't reach it, and its earthquake risk is moderate.

Budget for hail in your home insurancePlan for it

Front Range storms bring hail, and insurers price it in. Colorado's average homeowners premium is $4,310 a year, the highest of any state here, and it rose 18.3% in 2025. The flip side: Denver's overall natural-disaster risk is the second-lowest of the 13 metros, with no hurricanes and moderate earthquake risk.
