Are you thinking about visiting Yosemite National Park in September? You’re in luck! September is an ideal time to explore the park. In September, Yosemite combines the vast array of activities available during the summer months with comfortable cooler temperatures – perfect for hiking and other outdoor activities.
But what can you really expect?
Keep reading for a deep dive into everything that Yosemite has to offer, and what to expect.
Weather in September
It’s easy to imagine early Yosemite park visitors bumping down dirt roads on the way to visiting Yosemite after taking a horse-drawn stagecoach ride at the Yosemite History Center.
Choose Your Own Temperatures
There isn’t just one answer to what to expect for temperatures in September in Yosemite.
Because Yosemite spans sun-soaked foothill climates at 1,800 feet (549 m) to craggy alpine summits at 13,114 feet (3,997 m), you can find a range of temperatures in the park on any given day. This allows you to choose your own temperatures by choosing activities at lower or higher elevations.
If you’re exploring Yosemite Valley or Wawona, you’ll be at around 4000 feet (1,220 m). The average high temperature for September in Yosemite Valley or Wawona is 83℉ (28℃) and the lows are 51℉ (11℃) on average.
However, if there’s a heat wave during your visit, or you prefer cooler temps, consider visiting Tuolumne Meadows. At 8,600 ft (2,622 m), the high temps average a very comfortable 65℉ (18℃) while evenings drop to a brisk 32℉ (0℃).
Looking for something in between? Try hikes along Glacier Point Road that are around 7000 ft (2,134 m)
Precipitation in September
September is still comfortably within Yosemite’s “dry season”. However, we will occasionally see some afternoon thunderstorms that tend to build over the high country in Tuolumne and can spill down into the lower elevations as well.
Because September tends to be dry, there is also a possibility of smoke and fire throughout California between late June and the beginning of the wet season – usually in mid- or late-October. It’s a price we pay for so much glorious sunshine.
What to Pack to Wear in Yosemite in September
You may have noticed that Yosemite’s temperatures fluctuate a lot between day and night. Plus, since you’ll probably want to explore several different areas within Yosemite National Park, it’s important to arrive with a variety of layers of clothing.
This layering strategy allows you to start with a puffy jacket in the morning. Pull off that jacket and enjoy long sleeves as the day starts to warm up, and then shed even that layer to be comfortable in short sleeves for mid-day.
We recommend carrying a light rain jacket too. It can double as a wind-breaker, and adds a lot of warmth for the amount of space it takes in your pack. Plus, if you are treated to an afternoon thunderstorm, you’ll be glad you have it with you.
Similarly, you might want to trade a warm wool beanie for early morning outings for a sun hat later in the day.
Hiking or trail running shoes with good traction are ideal for walking Yosemite’s sometimes-polished granite.
September is often still warm enough to enjoy a refreshing swim in one of Yosemite’s rivers or lakes. If that sounds like the perfect end to a day of hiking and exploration, be sure to grab a suit and towel too.
How Busy is Yosemite in September?
By September, Yosemite National Park feels calmer, especially mid-week. Schools are back in session, so there are fewer families traveling. There are still plenty of people visiting, but it’s like the park has taken a nice deep breath.
Weekends are busier than weekdays. If you have flexibility in your travel plans, be sure to take advantage of quieter mid-week days in Yosemite.
Yosemite National Park Service has started a text messaging service with information about when parking fills in various parts of the park. We’d recommend signing up for that a few weeks before you plan to visit so you can get an idea of what areas fill (and which do not) and at what times. That will give you a rough sense of when you should plan to arrive in different locations.
Sign up for current traffic conditions by texting YNPTRAFFIC to 333111.
Where to Stay in Yosemite in September
Escape to a cabin in Yosemite. You’ll find a great selection (and deals) at The Redwoods In Yosemite.
While Yosemite’s visitation is past-peak in September, we still recommend booking your lodging reservations early to get the best selection. Yosemite Valley lodging in particular can fill far in advance.
Check out booking a vacation rental cabin in Wawona instead. The Redwoods In Yosemite has the largest collection of cabins inside the park and plenty of filters that make finding the perfect place, and don’t forget to check out the special offers to get the best deal.
Best Hikes in Yosemite in September
September is a hiker’s paradise in Yosemite. The high country trails are open with many options for walking to an alpine lake or past soaring cliffs. Water flow has receded as the high-country snow melted away, so the waterfalls will be smaller (or gone) but you will be more likely to keep your feet dry by crossing on stones over small creeks rather than having to wade.
Mist Trail/John Muir Trail
Yosemite Valley lies at the heart of the national park, and there are many trail options ranging from short wheelchair and stroller-friendly walks through Cooks Meadow, to the steep trails that climb up from Yosemite Valley floor that provide birds-eye views.
However, with two big waterfalls that run year-round, the Mist Trail is the best, most popular, and most-scenic hike any time of year, and particularly in September. The trail is steep, but there are so many jaw-dropping destinations along the way it’s easy to customize to the hiking ability of your group. Whether you turn around at the Vernal Fall footbridge after getting that view of Vernal Fall (1.6 miles/2.6 km round-trip), the top of Vernal Fall (2.4 mi/3.9 km round trip) or make it all the way to the top of Nevada Fall (5.4 mi/ 8.7 km round trip), you’ll be in for a real treat.
Take the free shuttle in Yosemite Valley to Happy Isles (Shuttle Stop #16) or walk the extra 1.5 miles round trip from Curry Village.
Taft Point / Sentinel Dome
The trailhead for these two destinations starts at the same spot along Glacier Point Road. You can either do them one at a time or combine them into a longer loop with stunning views looking down into Yosemite Valley.
Taft Point is known for its striking fissures and the dizzying view from the guard rail down into the valley. Sentinel Dome provides an impressive 360 view of Yosemite’s high country as well as looking across at Half Dome and down into Yosemite Valley.
As separate hikes, each destination is 2.2 miles/ 3.5 km round trip with mostly rolling terrain – although the final climb to the top of Sentinel Dome is quite steep – take your time and enjoy the scenery.
As a loop, expect about 5 miles/ 8 km. The section of trail connecting the two destinations follows the valley rim and is a less-traveled treat.
As long as you’re driving out along Glacier Point Road, don’t forget to stop at Glacier Point too. It’s a particularly good destination for sunset.
Mariposa Grove of Giant Sequoias – Grizzly Giant Loop
The Mariposa Grove is the largest of the three giant sequoia groves in Yosemite National Park and is located close to Wawona and the South Entrance Gate. A stroll among these ancient giants is always worth the time, especially if you haven’t had the chance to see a giant sequoia before.
In September, most people will park near the South Entrance and take the free shuttle bus to the Arrival Area at the Lower Grove, though you can also walk the Washburn Trail (2 miles/3.2 km) if you want to stretch your legs.
From there, the most popular hike is the Grizzly Giant Loop (2.0 mi/ 3.2 km round trip) which takes you past the Fallen Monarch, Bachelor and Three Graces, and up to the Grizzly Giant (one of the largest trees in the grove). Just past the Grizzly Giant, you can walk through a living sequoia, the California Tunnel Tree.
However, you could also simply follow the wheelchair-friendly boardwalks around the Big Trees Loop (0.3 mi/0.4 km) for a shorter walk. For more time among the giants, hike the Mariposa Grove Trail plus Guardians Loop (7 mi/ 11.3 km round trip) to take in the (quieter) Upper Grove trees as well.
Cathedral Lakes Trail
Like Yosemite Valley, it’s hard to choose just one best hike in the Tuolumne region, but the Cathedral Lakes Trail is certainly a strong candidate. On this trail, you combine the serene beauty of Lower Cathedral Lake with the striking summits of Cathedral, Echo, and Tressider Peaks rising all around. The round-trip is 7-8 mi (11.2-12.8 km) depending on whether you want to see Lower Cathedral Lake, Upper Cathedral Lake, or both of them.

Sightseeing / Wildlife Viewing in Yosemite
So much of Yosemite’s beauty can be appreciated from roadside stops. Take a scenic tour up toward Glacier Point or out along Tioga Road as well as through Yosemite Valley.
Be sure to keep your speed down and your eyes open for some of Yosemite’s magnificent wildlife as you go. If you’re lucky, you may see one of Yosemite’s black bears (they can be brown or even blonde), mule deer, bobcats, coyotes, and so many more.
Photography
It may be hard to take a bad picture in this amazing place, but if you’re interested in coming away with the best photos possible, also consider joining The Ansel Adams Gallery for one of their photography walks.
Fall foliage in Yosemite Valley and Wawona usually peaks in mid-October, but keep your eyes open for small pops of color starting in September.
Rock Climbing
Go Climb a Rock. Yosemite is world-famous for amazing rock climbing. You’ll love the unique experiences and views from high atop Yosemite’s cliffs. Yosemite Mountaineering School offers beginner classes all the way up to multi-day ascents of El Capitan, and the Southern Yosemite Mountain Guides can introduce you to climbing just south of the park.
Swimming
There is a splashing good time to be had on the rivers in Wawona.
The days are still warm enough in September to enjoy a refreshing swim in Yosemite’s rivers or lakes. Wawona is particularly known for its delightful swimming holes. You might also enjoy swimming in the Merced River in Yosemite Valley or the sandy beach at Tenaya Lake along Tioga Road.
Go Stargazing
There’s nothing quite like finding a quiet spot away from the bright lights of the city to appreciate the beauty of the night sky. In September, you might even see a shooting star. The September Epsilon Perseids (not to be confused with the August Perseids from the Swift-Tuttle comet) add an extra spark of celestial excitement to the experience.
