Colorado Rockies Weather Playbook: Coors Altitude, Division Air Density

By Kevin Roth, sports meteorologist. How weather affects the Colorado Rockies at home and on the road.

Home advantage

Coors Field at 5,197 feet is the single most weather-affected park in the majors. Air density at that elevation is roughly 82 percent of sea level, which drives the highest run environment in baseball regardless of surface weather. Warm dry afternoon and early-evening starts are the maximum-carry conditions. Rain-delayed or cool wet games are the only times Coors plays anywhere near neutral.

Division road environments

NL West gives the Rockies Chase Field roof-closed baseline, Dodger Stadium onshore, Petco marine, and Oracle Park bay wind. The team travels from the highest-altitude park to the densest sea-level marine air repeatedly.

For DFS and bettors

Coors always plays higher than season-average totals suggest. Warm dry conditions push totals further up. The humidor still reduces carry compared to pre-2002 but the park remains the top run environment in baseball. Road Rockies games in dense marine air are the reverse trade.
