Registration timing is one of the few things in camp planning where being early is free. Waiting six weeks on the wrong camp costs you a slot; waiting six weeks on the right camp costs you nothing. Here is how the 2025 sellout pattern actually played out across our 19,500-camp catalog, and what it tells you about 2026.
What sold out earliest in 2025
The earliest sellouts in 2025 were small-capacity specialty programs in dense metros. Coding and robotics sessions at established brands in Los Angeles, the Bay Area, and New York City closed their popular June and early-July weeks by mid-February. Sleep-away camps with strong alumni programs often fill by January 30 for returning campers, and their public registration opens and closes the same week. Sports academies with named-coach programs (basketball, tennis, soccer) pattern similarly — the two weeks flanking July 4 go fastest.
Mainstream day camps fill differently. They don’t sell out in a rush; they drain week by week. In 2025, the second and third weeks of June closed first in LA and NYC, usually by late March. August weeks were still broadly available in May, even at premium brands. The pattern held in second-tier metros with a lag of roughly three weeks. Small-town and rural camps mostly had availability into late April for every week of the summer.
Registration windows by camp type
Use the camp type to set your registration target. Overnight camps: register by February 1 for the current summer if the camp is established and in demand; by March 1 for mid-tier overnight; April 1 is usable for smaller operators. Specialty and STEM programs: February 15 for top-decile brands in big metros; March 15 for established mid-tier; May 1 for newer or suburban operators. If you’re looking at tech specifically, browse LA STEM camps and you’ll see the capacity tiers — the small ones close first.
Mainstream day camps: February through late March for the three most popular weeks (late June and the two weeks around July 4); April is still fine for the other weeks. Parks-and-rec and YMCA camps: registration typically opens in February but capacity is huge, so even May registration usually works. Arts intensives and audition-based programs follow their own calendars — check each website for the audition window rather than a general rule.
When waitlists actually work
Waitlists are underrated for day camps and overrated for overnight. Day-camp waitlists in our 2025 snapshot cleared 10 to 25 percent of their queue between May 15 and the week before session start, as families’ work schedules shifted and kids changed their minds. If you are on a day-camp waitlist at position 10 or better, you will probably get in. At position 25, you might; at position 50+, plan around not getting in.
Overnight camps move differently. Families who put down $1,500 in February do not let slots go. Overnight waitlists cleared 5 percent or less between April and June in 2025. If you are waitlisted for overnight, assume you are not getting in and register for a day camp or a different overnight program as your real plan. The exception is “ghost slots” — overnight camps occasionally add capacity in May if staffing comes together — but that is not something to bank on.
Cities where timing matters most
The cities where timing matters most are the ones with the worst supply-demand ratio: camps per school-age kid. In 2025 the tightest markets were the SF Bay Area, Manhattan/Brooklyn, Washington DC, Seattle, and Greater Boston. In those markets, February is the real deadline for most camps a working parent can build around. Browse the full San Francisco Bay Area camp directory or NYC camps directory and you’ll see the capacity relative to the population.
Second-tier metros — Austin, Denver, Atlanta, San Diego, Portland — have enough supply that March registration is usually fine, with selective early February registration for the top few specialty brands. Third-tier and smaller metros generally give you until April, with local summer institutions (a single beloved arts camp, a single hiking camp) being the exceptions. The rule of thumb: if the camp is the thing everyone’s friend tells them about, register February 1. Otherwise, register by the refund cliff at the pace your family actually wants to commit.
