Who this is for: skiers and snowboarders who can travel and want to match the calendar to the mountains most likely to deliver. Each month names one or two lift-served areas whose own records, stats or announced dates support the pick, plus what to expect and what to check before you book.
How we chose: this is desk research, not a field test. We used resort-published statistics, season dates the resorts announced, and season-length records for the 2025-26 winter. Opening and closing days always depend on snow. Treat every date below as a pattern or a past result, not a promise, and confirm the current season on the resort's own site before you pay for anything. Last updated November 10, 2026.
Quick picks by month
| Month | Best bet | Why |
|---|---|---|
| October | Arapahoe Basin, Colorado | Usually first to open in Colorado |
| November | Killington, Vermont; Alta, Utah | Early-opening East; Alta's announced opener |
| December | Whistler Blackcomb, British Columbia | Biggest terrain in North America, holiday-ready |
| January | Alta, Utah | Deep, light Wasatch powder |
| February | Revelstoke, British Columbia | Longest lift-served vertical on the continent |
| March | Jay Peak, Vermont | The East's snowiest mountain |
| April | Mammoth Mountain, California | High-elevation spring with a long season |
| May | Arapahoe Basin; Killington | Late closers in the West and East |
| June | Mammoth (early June); Beartooth Basin; Timberline | The last winter lifts and the summer-only crowd |
| July | Timberline, Oregon; Beartooth Basin | True summer skiing |
| August | Timberline, Oregon | Palmer Snowfield, usually into late summer |
| September | No reliable pick | The off month: tune gear and train |
October: Arapahoe Basin, Colorado
A-Basin calls itself the longest ski and ride season in Colorado, with an earliest opening day of October 9 (A-Basin). Half the mountain sits above timberline, and the area says it generally opens in October (A-Basin). In 2025-26 it opened October 26 (SnowSure).
- Expect: one or two man-made-snow runs, not the bowls. October skiing is about the first turns, not variety.
- Tradeoff: limited terrain and crowded opening weekends. Keystone, nearby, opened October 25 in 2025 (SnowSure), which gives you a second option in Summit County.
- Check: opening announcements and whether beginner terrain is open.
November: Killington, Vermont, and Alta, Utah
In the East, Killington opened November 12 in 2025 and ran 194 days (SnowSure). In the West, Alta announced a projected 2026-27 opening day of November 20, conditions permitting (Alta).
- Expect: early-season coverage. Killington's opening terrain usually leans on snowmaking, and Alta's opener depends on natural snow.
- Tradeoff: November is a gamble anywhere. Book refundable lodging.
- Check: Alta is skiers only, so snowboarders should look elsewhere (Alta).
December: Whistler Blackcomb, British Columbia
Whistler Blackcomb lists 8,171 acres, more than 200 marked runs, 16 alpine bowls, 3 glaciers and a 422-inch average snowfall (Whistler Blackcomb). Blackcomb's 5,280-foot vertical is the bigger of the two mountains (Tourism Whistler).
- Expect: a huge range of terrain even before the alpine is fully open, plus a full village for the holidays.
- Tradeoff: the base sits at 2,214 feet, so lower runs can be wet in mild storms (Whistler Blackcomb). Holiday weeks are the busiest and most expensive.
January: Alta, Utah
Alta averages 543 inches of snow each winter, and its record season was 903 inches in 2022-23 (Alta). The area credits its light snow to an average density of about 8.5 percent (Alta). January usually brings cold storms after the holiday crowds leave.
- Expect: steep, deep powder days. Alta says 45 percent of its terrain suits beginner and intermediate skiers (Alta).
- Tradeoff: Little Cottonwood Canyon road closures and traffic on storm days. Skiers only.
February: Revelstoke, British Columbia
Revelstoke lists 5,620 feet (1,713 m) of vertical, the longest descent in North America, plus 3,121 acres and an average of 10.5 m (34.4 feet) of snow (Revelstoke). Its longest run, The Last Spike, is 15.2 km (Revelstoke).
- Expect: a deep midwinter snowpack and four bowls when the alpine is open.
- Tradeoff: 45 percent of the runs are rated advanced, so it's best for strong skiers (Revelstoke). It's a long drive from major airports.
March: Jay Peak, Vermont
Jay Peak averages 356 inches of snow a year, the most east of the Rocky Mountains, according to its operator (Pacific Group Resorts). It has 385 acres, 2,153 vertical feet and more than 100 acres of glades.
- Expect: March is often the East's best month for coverage, with deep glades and longer days.
- Tradeoff: smaller terrain than western resorts and harsh wind on the upper mountain. The tram runs only when the wind allows.

April: Mammoth Mountain, California
Mammoth ran 200 days in 2025-26, from November 20, 2025 to June 7, 2026 (SnowSure), and announced June 7 as its closing day (Mammoth Mountain). Its high elevation keeps spring snow longer than most of California.
- Expect: sunny spring snow that firms up in the morning and softens by midday.
- Tradeoff: dry years end early. Mammoth finished 2025-26 with 297 inches at Main Lodge, below its usual average (Tahoe Ski World).
May: Arapahoe Basin and Killington
A-Basin's latest closing day on record is August 10 (A-Basin). In 2025-26 it closed May 17 (SnowSure). In the East, Killington skied until May 24, 2026 (SnowSure).
- Expect: spring snow, short ski days and festival weekends.
- Tradeoff: closing dates change with the snowpack, so book late and flexible.
June: Mammoth's last days, Beartooth Basin and Timberline
Early June can still mean Mammoth in a big year. Beartooth Basin, a summer-only ski area on Beartooth Pass, operates on the Shoshone National Forest and reopens around Memorial Day (Beartooth Basin). It has two Poma surface lifts and no lodge, and it cancelled its 2024 season for lack of snow (Roaming Montana). At Timberline on Mount Hood, Palmer Snowfield serves the public from June through August (Timberline).
- Tradeoff: Beartooth Basin is backcountry-style, at about 10,900 feet, and not for beginners.
July: Timberline and Beartooth Basin
Beartooth Basin typically closes by early to mid July (Roaming Montana). Timberline keeps public terrain open alongside race and freestyle camps (Timberline).
- Expect: morning laps on firm snow and slush by afternoon.
- Tradeoff: camps reserve some lanes, so public terrain is limited.
August: Timberline, Oregon
The Palmer Express usually runs from about June 1 to Labor Day, according to Ski Oregon (Ski Oregon). The summer season runs only as long as the snowpack lasts.
- Tradeoff: intermediate and advanced terrain only, and an early end in low-snow summers.
September: the off month
We found no North American lift-served area that reliably operates in September. Timberline says its summer skiing ended for 2026 (Timberline). Use September to tune skis, check boots and plan the winter.
Before you book any month
- Confirm opening and closing days on the resort's site the week you travel.
- Check road and pass conditions, especially in Little Cottonwood Canyon, Beartooth Pass and mountain highways in British Columbia.
- Pack layers for the month, not the postcard. Spring and summer skiing still bring cold mornings and strong sun at altitude.
- Use the Wild10 weather report for history and forecasts for your dates, and browse Wild10 destinations to plan around them.
