USA REPORT
There are four U.S. ski centres open after Arizona Snowbowl closed on Sunday, having made it into June for the first time in its eight-decade history. Still operating are California’s Mammoth Mountain (52/100” / 130/250 cm), Colorado’s Arapahoe Basin (6/48” / 15/120 cm), and Timberline ski area (0/112” / 0/280 cm) in Oregon. Copper Mountain's hike-to-summer terrain park has also opened, tied to its Woodward Summer Camps, but available at times to non-campers as well. The Beartooth Basin summer ski area in Wyoming, near the Montana border, has also re-opened for the first time in two years. It reported a “great opening day with good skiing and happy vibes” last Thursday. On Saturday, it was so popular that tickets sold out.
The area is hoping to stay open at least through June, but closing dates may come sooner for Mammoth and A-Basin. The latter is aiming to make it at least to mid-month, thanks to a still-solid 50”+ (125 cm) snowpack. Mammoth announced on Monday that it will end its season on June 15th, bringing its 7.5-month 2024–25 season to a close. Mammoth and Timberline remain open daily, while Arapahoe Basin is now closed Monday through Thursday but will reopen for skiing this Friday, Saturday, and Sunday — June 6, 7, and 8, from 8:30 AM to 2:00 PM.
“Regarding skiing beyond June 8, let’s be a little patient and see what the weather does. Anything is possible,” a spokesperson said.
Mammoth Mountain is currently offering the most terrain still open — about 30% of its full extent. Most of the open ski areas have seen mostly sunny weather over the past seven days, with temperatures ranging from around freezing at higher elevations overnight to the high 50s or low 60s in the afternoons. This means some freeze-thaw overnight on upper runs, but spring (or perhaps now summer) slush is arriving ever earlier in the day.
USA FORECAST
Sunny, warm weather continues on the Pacific Coast, with overnight lows now only dropping into the 40s (°F) and daytime highs reaching into the 70s. Cooler and more changeable conditions are expected in the Rockies, with Arapahoe Basin likely to see freezing temperatures on its highest slopes and some light overnight snowfall (up to 2” / 5 cm). Daytime highs there are expected to reach the 50s.
