The short answer
Work backward from opening day and the calendar sets itself. For a winter that starts the week of Thanksgiving, the answer to when to hire seasonal staff is: postings live in the first half of August, first offers out by mid-September, roster closed by Halloween, and a named backup for every safety-critical role.
Jackson Hole Mountain Resort has already published November 27, 2026 as opening day for the 2026-27 season. Count back from there. Orientation the week before. I-9s and payroll setup the week before that. Housing move-ins landing mid-November, which means a signed housing agreement in October, which means an accepted offer in late September.
That puts a small operation roughly six weeks behind the largest employers in town and roughly six weeks ahead of where most twelve-to-forty-person businesses actually post. Only one of those gaps is a problem.
The competitive calendar, July through December
July. Vail Resorts tells applicants its winter seasonal postings go live in early July, high-volume departments first: ski school, lift operations, guest services, retail and rental. Alterra properties and the independents follow through July and August. By the first of August, a 22-year-old who wants a lift op job in Breckenridge has seen four postings for one.
You are not going to win July on volume, and you shouldn't try. July is for the list you already have.
August. Applications pile up at the big operators, but their hiring is a funnel, not a gate. They keep hiring into December. What actually gets absorbed early is a specific slice of the pool: people who need housing solved before they'll commit, and who will trade a dollar an hour for that certainty. That is the same slice you want, and August is when it moves.
So post in August, with the housing answer inside the posting rather than in a follow-up email three exchanges later. Writing a seasonal job posting that answers the housing question covers what that line has to contain to be worth anything.
September. Offer season, and the month the immigration paths close if you're on one. The H-2B timeliness rule described below is 75 to 90 days before your date of need, so a December 1 start puts the filing window in the first half of September. Miss it and the date of need moves, not the deadline.
October. Housing decides it. A candidate holding two offers takes the one that answers February rent, and by October the answer has to be concrete: an address, a weekly number, a move-in date. October is also the deep shoulder in Jackson and Summit County. Most of the seasonal workforce has already left town. The people still around are year-rounders, returners, and the genuinely committed, which makes October outreach small in volume and unusually high in quality.
November. Backfill month, and the month your no-shows announce themselves. Build the schedule assuming some share of your accepted offers won't walk through the door, because that is what a long gap between offer and start does to a workforce that is young, mobile, and holding other options.
December. Whatever is still open gets filled at a premium, covered by overtime, or not covered at all. Overtime is the expensive default and it is not always as cheap as the schedule makes it look, particularly in Colorado and California. The wage-and-hour rules for seasonal operations go through why.
Three counter-moves for an operator who can't outspend anyone
Move your offer date, not your posting date. The large employers post early and decide slowly, because a corporate funnel has to process thousands of applications through a shared system. A twelve-person outfitter can interview on Tuesday and put a written offer out on Friday. That speed is the single durable advantage you have, and it disappears the moment your posting sits in an inbox for two weeks. If you can't turn a qualified applicant around in five business days, posting in August buys you nothing.
Lead with housing, not with culture. A posting that says "housing available" and a posting that says "shared room in a three-bedroom in Silverthorne, $185/week deducted from pay, move-in November 12, water and heat included" are not competing for the same candidate. The second one is doing the job. If you have no housing, say so plainly and name what the nearby-town commute actually looks like in February, because the candidate is going to find out in February either way.
Work the shoulder for returners. April and May, and again in October, are when the reachable people are reachable. They are between seasons, deciding where to go next, and not yet buried in an application pipeline. A short direct message in the shoulder to everyone who finished a season with you and left on good terms is the cheapest hiring you will ever do. It also compounds: an operation with a real returner base spends October confirming, not recruiting.
The tradeoff: post too early and you'll pay a re-confirmation tax
Every week you move the offer earlier is another week a candidate can change their mind, and the cost of that is not zero. A September offer for a late-November start needs a check-in at 30 days and again at 10 days, a housing agreement or deposit that creates something to walk away from, and someone whose job it is to notice when a reply goes quiet. Push the offer to early August and you have added six more weeks of that, plus the awkward reality that a candidate who accepted in August has been fielding better offers ever since.
Ten to fourteen weeks between accepted offer and first shift is where the tradeoff sits for most winter operations. Earlier than that and you are not hiring sooner, you are just re-confirming for longer.
If you're weighing H-2B or J-1
Neither one is a shortcut, and both are worth understanding before you rule them out.
H-2B is capped by statute. Congress has set the annual limit at 66,000, split into 33,000 for start dates from October 1 through March 31 and 33,000 for the second half of the year. Applications requesting an October 1 start go through a three-day filing window; for 2026, that window ran July 3 through July 5. Later start dates follow the standard rule: the application must be filed no more than 90 and no fewer than 75 calendar days before the date of need. On top of that you are paying for a prevailing wage determination, a state job order, domestic recruitment, counsel, and inbound travel, and you are committing to the three-quarters guarantee. For an outfitter filling four positions, the per-head cost usually doesn't pencil.
J-1 Summer Work Travel is the lighter lift, and it is the reason so many winter resort employees are from Chile, Argentina, Peru, and Brazil. Participants come during their university break, which for Southern Hemisphere students falls across the North American winter, and the program runs through State Department-designated sponsors rather than through you directly. Placements for a December arrival get matched in the fall. The catch is that the participant's dates are set by their university calendar, not your season, and you are agreeing to help with housing and to treat the placement as cultural exchange rather than pure staffing. Employers who read that as boilerplate tend to have a bad year.
What to do before Labor Day
Pull last season's roster and message every person on it who you'd rehire. Write the housing line for each open role, with a number in it. Put the postings live. Set a five-business-day clock on every application and put one person's name on it. Then decide, in writing, what your December contingency is, because you will need it.
TurnSeasons is built for exactly this window. You can post a role and reach seasonal workers who are searching for jobs and housing together, or start from the town you're hiring in.
