Arapahoe Basin Ski Area in Summit County, Colorado, concluded its 2025-26 skiing season on Sunday, May 17 [4].

The closing marks the end of a volatile winter where unusually warm temperatures and low snowpack threatened early closures. The timing of the final day highlights the unpredictability of high-altitude weather patterns in the U.S. West.

Initial reports suggested the resort would close on Sunday, May 3 [3]. However, the ski area extended operations for an additional weekend after receiving more than one foot of fresh snow [1]. This late-season surge allowed the resort to keep its slopes open through the weekend of May 15-17 [5].

The total length of the season reached 194 days [2]. This duration reflects the resort's effort to maximize the window of operation despite the challenging environmental conditions experienced throughout the winter.

Skiers and staff gathered for the final day of operations in Summit County. The extension provided a brief reprieve for enthusiasts seeking spring skiing before the summer melt begins.

“The ski area extended operations for an additional weekend after receiving more than one foot of fresh snow.”

The discrepancy between the initial May 3 closing date and the final May 17 date illustrates the precarious nature of modern ski season planning. As winters become warmer and snowpacks more inconsistent, resorts are increasingly reliant on short-term, high-volume weather events to extend their revenue windows and satisfy consumer demand.
