December Campsite Openings, Counted

The week table first, because it is the month's shape:

Stay starts	Confirmed openings	Share of December
Dec 1–7	492	55.4%
Dec 8–14	105	11.8%
Dec 15–21	122	13.7%
Dec 22–31	169	19.0%

More than half of December's counted flow sits in its first week, and that is a calendar artifact in the honest sense: December 1 is the first stay date a 30-day rolling release could reach from the day our window opened, and it arrived as one. Of the 173 openings for December 1 stays, 71 were detected at exactly 30 days of lead — the fingerprint the release-cliffs post taught readers to recognise — led by Crystal Lake (37); Santa Cruz Island Scorpion (29); Kipahulu Campground (19). The mid-month weeks (105 and 122) are thinner because their cancellation heartland has not happened yet: a December 15 stay gets most of its cancellations in early December, a fortnight from now. The late-month bucket (169) is already the month's second largest because it holds the holidays, whose holders decide earliest. Every figure in this post is a floor that rises daily; the shape — releases first, cancellations later — is the part that will not change.

The December specialists

The facility table is a climate map again, sharper than November's. The five deepest December flows are Kipahulu Campground (103); Upper Pines Campground (78); Santa Cruz Island Scorpion (72); Furnace Creek Campground (53); Fort Pickens Campground (43). Two of them are December specialists in a way no November facility was: Kipahulu Campground's 103 December openings are the majority of everything Kipahulu has produced in the log (103 of 162), because Haleakalā's 30-day window means December is simply the month its release calendar is currently serving. Santa Cruz Island Scorpion, off the California coast, shows the same signature — 72 December openings, 41.6% of its total flow (173) — an island campground whose December is high season in everything but temperature. Upper Pines (78 December openings) is the list's all-weather entry: Yosemite Valley recycles in every month the log has seen. The practical reading: a December hunter's watch list is short and knowable, and it is printed above.

The shape of a December stay

Night counts: 389 single nights, 209 two-night stays, 184 of three or four nights, and 69 of five or more — excluding one disclosed distortion: 37 of December's openings are Crystal Lake's whole-month calendar blocks at exactly 31 nights, a single facility's booking pattern that this post counts in the totals (888 includes them) and excludes from the stay-shape reading, exactly as the month-long analysis was handled in earlier waves. Underneath that footnote the shape matches the system-wide table in most openings are one night, with December's two-night share fattened by weekend-shaped holiday trips. A hunter who needs a full December week is, as ever, assembling fragments — but December's fragments arrive earlier than November's did, at a median lead of 34.5 days, which makes assembling them a planning exercise instead of a scramble.

Why December openings wait longer — and why that is not a December fact

The survival contrast is real: 10h 18m for December stays (n=213) against 5h 10m for November (n=4452). It would be easy to headline that as December being a slower, kinder market. The log does not support that headline, and this post does not print it. December's flow is dominated by far-ahead inventory — 850 of 888 openings (95.7%) arrived at 28 or more days of lead — and survival by lead time already established that far-ahead openings live longest in any month, because they are disproportionately scheduled releases meeting planners rather than contested cancellations meeting hunters. The honest comparison is inside the cohort: December stays detected at 30+ days of lead survive a median 11h 39m (n=202), squarely in the far-cohort range the lead-time table predicts. November's own 30+ day cohort is still too small to compare against (n=19 completed cycles), so no month-versus-month claim is made. What a December hunter can bank is narrower and more useful: the openings appearing now, for December, are the slow kind — there is time to see the alert, check the calendar, and book like a person.

The holiday windows, sized honestly

Christmas stays (December 24–27) stand at 69 confirmed openings and New Year stays (December 28–31) at 72. Both windows are real and bookable — the deepest Christmas flows are Indian Cove Campground (11); Upper Pines Campground (6); Furnace Creek Campground (6); for New Year, Pinnacles Campground (7); Fort Pickens Campground (6); Indian Cove Campground (5) — and both are still early versions of themselves: their 14-day release cohorts land in mid-December and their cancellation heartland in the final week, so these counts will be the fastest-growing numbers on this page's next rebuild. With 20 and 14 completed life cycles respectively, any survival figure would be a handful of openings wearing a statistic's clothes; the Thanksgiving post could publish a holiday survival median at n=138, and this one holds itself to the same standard. Set the watch now, while the flow is still the slow far-ahead kind — that, and not a survival median, is December's actual gift to a hunter.

The limits, plainly

The window is young (scanning since Oct 29, 10:54 PM ET), so December openings that recycled before it opened are invisible and every count is a floor. The month's composition will change as its own cancellation heartland arrives: by mid-December the median lead will fall and the survival median with it, and a future rebuild of this post will show a different — more November-like — December. Watch depth also favours famous warm-edge parks over obscure ones. What survives the caveats is the count itself and its structure: 888 verified December openings at 72 named campgrounds, arriving early, on release schedules a hunter can read in advance.
