Yosemite crowd calendar.

By Nicholas Major · Last updated

August is Yosemite's busiest month at about 537,000 average recreation visits, essentially tied with July, while January is quietest near 115,000, roughly 21% of that peak. What sets Yosemite apart from most marquee mountain parks is how flat its curve is: the ratio between the busiest and quietest month is under 5 to 1, one of the gentlest of any big western park. Yosemite Valley stays open and reachable all year, so even the winter months keep real traffic, with October still near 77% of peak and December around 28%. The heavy season stretches wide, from a spring ramp in April and May through a summer plateau and a strong autumn. The two natural in-between windows are April, at roughly 48% of peak, and November, near 40%. Because the whole warm half of the year runs busy, the quieter edges of the season matter more here than picking one summer month over another.

Yosemite's crowd calendar, month by month.

Each bar is a calendar month's average recreation visits over the last five years (2021-2025), shown as a share of Yosemite's own busiest month. The full numbers are in the table below, and every month links to its own detailed page.

Reading the shape of the year.

Yosemite's crowd curve is broad and rounded rather than sharp. July and August share the top at about 536,000 and 537,000 average visits, June is close at 508,000, and September (473,000) and October (413,000) keep the traffic high well into fall. The spring side climbs steadily: April near 256,000 and May near 383,000. The result is a long busy plateau that runs from roughly May through October rather than a single spike.

The defining feature is the floor. January, the quietest month at about 115,000 visits, still sits at roughly 21% of the August peak, and February, March, and December all stay in the same low-but-real band. That is unusual. Parks like Glacier or Acadia effectively empty out in winter, but Yosemite Valley stays open and drivable year-round, so the cold months keep a steady stream of visitors coming for firefall in February, snow scenery, and quiet valley walks. Even March, sitting near 25% of peak, holds more traffic than the busiest-to-quietest math at most seasonal mountain parks would predict for a shoulder month, another sign of how much year-round valley access flattens this curve.

Because the summer months barely separate from one another, there is little crowd advantage to picking July over August. The real levers are the edges. April, at about 48% of peak, catches the valley greening up before the summer wall of people; November, near 40%, comes after the autumn color fades but before winter fully sets in. October is worth calling out too: at about 77% of peak it is busier than many visitors expect, carried by fall foliage and still-open high-country roads. Read as a whole, Yosemite rewards visitors who can slide to the shoulder edges of a very wide season rather than those chasing a single quiet month.

The shoulder window

The natural shoulders are April (about 48% of peak, valley greening up) and November (about 40%, after the fall color). Winter stays quieter still but with a real floor because the valley never closes.

How to read this calendar

Every number here is a five-year monthly mean of Recreation Visits (2021-2025) from the official NPS Visitor Use Statistics Data Package, 2025. Each bar and table row is that calendar month averaged across the last five years, so one odd weather year or one road closure does not swing the shape. The "share of peak" column expresses each month against Yosemite's own busiest month, which is the honest way to compare a quiet month with a loud one. One limit worth stating plainly: this is monthly data, so it tells you which months are busy, not which days or weekends. For within-the-month timing, a holiday week or a summer weekend still runs busier than a plain weekday, but our data cannot measure that.

Common questions.

What is the busiest month at Yosemite?

August, at about 537,000 average recreation visits, essentially tied with July at 536,000. June through October is all busy season, with a wide summer-into-fall plateau rather than a single spike.

When is Yosemite least busy?

January, averaging about 115,000 visits, roughly 21% of the August peak. Yosemite Valley stays open all winter, so even the quietest month keeps a steady flow of visitors.

How do I avoid crowds at Yosemite?

Aim for the shoulder edges: April near 48% of peak or November near 40%. Winter is quieter still. Because the summer months barely differ, sliding a few weeks to either side of the busy season helps more than picking July versus August.

Is Yosemite crowded in October?

Busier than many expect. October averages about 77% of the August peak, kept high by fall color and still-open high-country roads. It is a strong month for scenery but not a low-crowd one.
