Denver's rainfall deficit deepens as wettest season approaches
Denver’s water year has seen far less rain than usual so far. Since October 1, the city has recorded just 3.13 inches of precipitation—well below the expected 6.55 inches. This shortfall leaves the area 3.42 inches behind normal levels as it enters its wettest season. The water year runs from October 1 to September 30, and Denver is now approaching its peak rainfall period. May, the city’s wettest month, typically brings 2.16 inches of precipitation. Even with normal rain in the coming weeks, the existing deficit won’t disappear entirely.
Rainfall in Denver plays a key role in improving soil moisture, cutting fire risks, and easing demand for outdoor watering. But drought recovery relies on more than local showers. Factors like mountain snowpack, runoff, reservoir levels, and where the rain actually falls all influence the bigger picture. For Denver to close the gap, the upcoming wet season would need to deliver above-average rainfall. Without it, the city will remain short of its usual precipitation totals.
The next few months will determine whether Denver can make up its rainfall deficit. While normal precipitation would offer some relief, it won’t fully erase the shortfall. The city’s water supply and drought conditions will also depend on broader factors, including snowmelt and reservoir storage.
