The 2026–27 ski season could begin before Halloween. From Colorado’s high peaks to Vermont and Maine, several mountains are already positioning themselves for the first chairlift ride of winter.
Within a matter of weeks, temperatures across the highest elevations of the Rockies and northern New England should begin dipping low enough for snow guns to fire. Then comes one of skiing’s great autumn traditions: the race to become one of the first ski resorts to open for the 2026–27 season.
Right now, Arapahoe Basin in Colorado is projected to open around October 24, which would put it at the front of the pack. But that date isn’t official yet.
Loveland, Keystone, Winter Park, Killington and Sunday River are all capable of moving quickly once the right combination of cold air, low humidity and natural snowfall arrives.
And there is always a wild card.
Here’s where the race stands as of September 5, 2026.
Projected 2026–27 Ski Resort Opening Dates
| Ski Area | Location | Current Opening Outlook |
|---|---|---|
| Arapahoe Basin | Colorado | Around Oct. 24 projected; official date TBD |
| Loveland Ski Area | Colorado | Mid-October to early November |
| Winter Park | Colorado | “As soon as possible”; Oct. 30 currently projected |
| Keystone | Colorado | Around Oct. 31 projected |
| Killington | Vermont | No fixed date; opens as soon as conditions allow |
| Sunday River | Maine | Typically late October to early November |
| Banff Sunshine | Alberta | Early November |
| Brian Head | Utah | Nov. 6 scheduled |
| Lake Louise | Alberta | Nov. 6 scheduled |
| Wolf Creek | Colorado | Weather dependent—a major early snowstorm could change everything |
Important: Opening dates are highly weather dependent. Some dates above are resort targets, while others are industry projections rather than confirmed opening days.
1. Arapahoe Basin Is the Early Favorite
If you had to pick a leader today, Arapahoe Basin—better known as A-Basin—would be hard to bet against.
The Colorado ski area’s unusually high elevation has helped make it a perennial contender for some of the earliest skiing in the country. Current industry projections place its 2026 opening at October 24, although A-Basin itself continues to list opening day as TBD.
That distinction matters.
A-Basin doesn’t simply flip a switch on a predetermined date. It needs sustained cold weather to build enough machine-made snow on its opening route—and a few warm October afternoons can erase the advantage created by several chilly nights.
Still, if October delivers an early Rocky Mountain cold snap, A-Basin will be one to watch closely.
2. Don’t Count Out Loveland
Just down the Continental Divide, Loveland Ski Area may be A-Basin’s most interesting challenger.
Loveland says it hopes to open for the 2026–27 season sometime between mid-October and early November, with snowmaking typically beginning in early October.
Loveland has history on its side, too.
Its earliest opening in the modern record came on October 7, 2009, and the mountain opened Oct. 15 in 2008, Oct. 14 in 2011 and Oct. 17 in 2013.
That makes Loveland particularly interesting because it isn’t tied to a single date.
If Colorado gets several cold, dry nights in succession, the resort can take advantage.
3. Winter Park Is Going With “ASAP”
Winter Park isn’t even pretending to know exactly when winter will arrive.
Its official operating information says the resort plans to open “As Soon As Possible (ASAP)” for the 2026–27 season.
Current projections put the date around October 30, but the real opening could move in either direction depending on conditions.
Winter Park opened on October 31 in 2025, so an October opening isn’t merely theoretical.
An extended stretch of cold nights during the second half of October could put Winter Park squarely into the race.
4. Keystone Has Upgraded Its Snowmaking
Keystone may have one of the more intriguing advantages this year.
The Colorado resort has invested in a more automated and efficient snowmaking system specifically designed to improve early-season production. Keystone says the improvements could help move opening day forward by as much as three weeks under ideal conditions, with the system ready to begin producing snow once temperatures cooperate in early October.
Current projections point toward roughly October 31.
That puts Keystone within striking distance of A-Basin—especially if October delivers a prolonged window of cold and dry weather.
5. Killington Could Surprise the West
Don’t assume Colorado has this competition locked up.
Killington Resort in Vermont takes a remarkably simple approach to opening day:
It doesn’t set one.
Once temperatures are cold enough, its snowmaking crews get to work, and the resort opens when sufficient terrain is ready. Killington describes the period between opening day and mid-November as its early season.
That gives Killington flexibility.
If northern Vermont gets a sharp October cold spell while Colorado stays mild, the East could conceivably jump ahead.
6. Sunday River Is Another Eastern Wild Card
Maine’s Sunday River belongs in the same conversation.
The resort says it generally opens as early as possible, typically in late October or early November.
Like Killington, Sunday River operates an aggressive snowmaking system and can take advantage of relatively brief stretches of favorable temperatures.
An October blast of Canadian air into northern New England could suddenly make this a much closer race than current projections suggest.
7. Wolf Creek Is the Resort Nobody Should Forget
Then there’s Wolf Creek Ski Area in southern Colorado.
Wolf Creek is different because natural snow can dramatically change its timetable.
In 2024, Wolf Creek opened on October 22 after early snow arrived in the San Juan Mountains.
The resort traditionally leaves its opening date dependent on weather, temperatures and natural snowfall rather than committing far in advance.
That makes Wolf Creek the ultimate spoiler.
A powerful October storm could dump enough snow on the San Juans to vault Wolf Creek ahead of almost everyone.
Canada Could Join the Race in Early November
Two Canadian Rockies heavyweights won’t be far behind.
Lake Louise Ski Resort currently lists November 6, 2026, as the beginning of its 2026–27 winter season.
Banff Sunshine Village expects its winter season to begin in early November and extend into late May.
Those long Canadian seasons are another reminder that the first lifts can begin spinning nearly two months before the official beginning of astronomical winter.
Winter itself doesn’t officially arrive until December 21, 2026. See the 2026 season dates and times
What Actually Determines When a Ski Resort Can Open?
The answer isn’t simply “when it gets below 32°F.”
Snowmaking depends heavily on something called wet-bulb temperature, which factors both air temperature and humidity into the equation.
Cold, dry air is much better for making snow than cold, humid air.
A wet-bulb temperature around 28°F or below generally allows snowmaking to begin, while colder conditions dramatically improve efficiency.
That means a resort might be able to make snow when the ordinary thermometer reads slightly above freezing if the air is exceptionally dry.
Conversely, a humid 30-degree night may be much less productive.
This is why the first significant cold, dry October air mass can have an outsized effect on opening-day plans.
Why October Weather Matters So Much
An isolated chilly night isn’t usually enough.
To open a ski run, resorts need to build a deep and durable snow base, groom it and make sure the trail can safely handle thousands of skiers.
The ideal scenario is therefore not one night at 25°F.
It’s several consecutive nights—and preferably days—with favorable snowmaking conditions.
High elevation provides an enormous advantage.
That helps explain why places such as Arapahoe Basin and Loveland repeatedly emerge near the front of the opening-day race.
It’s also why an autumn storm accompanied by very cold air can suddenly move an unexpected resort to the head of the line.

What Does the Farmers’ Almanac See for Winter 2026–27?
The Farmers’ Almanac 2026–27 Winter Weather Forecast calls for a winter of strong regional contrasts, with an active southern storm track, periods of mountain snow and significant shifts between warmer and colder weather.
A strengthening El Niño is also expected to play an important role in the broader North American weather pattern.
That doesn’t tell us which ski area will open first—October weather operates on a much shorter timescale—but it could have significant implications for snowfall once the heart of ski season arrives.

So, Which Ski Resort Will Open First in 2026?
For now, Arapahoe Basin has the edge.
Its current October 24 projection is the earliest among the major U.S. resorts being tracked.
But we wouldn’t write the winner’s name on the trophy yet.
Loveland could capitalize on an early Colorado cold spell. Winter Park is explicitly trying to open as soon as possible. Keystone has improved its snowmaking. Killington and Sunday River are waiting for the first sustained New England cold. And Wolf Creek only needs one well-placed autumn snowstorm to turn the entire race upside down.
In other words, the calendar gives us contenders.
The weather decides the winner.
And once the first real cold arrives in October, this race could change very quickly.
