September is a transitional month for Grand Teton National Park; not only weather-wise, but crowd, wildlife, and scenery-wise too.

Visiting in September, you’ll enjoy cool daytime temperatures, fall colors, and fewer people visiting Grand Teton.

But there are some challenges too, including cold morning and night temperatures, unpredictable weather, and services and conveniences shutting down as the month of September goes on.

In this article, we break it down for you – how to make the most of the advantages, how to deal with the challenges, and make suggestions on when you should go in September.

Visiting Grand Teton in September - Advantages and Challenges

Advantage (The BIG One): Fall Colors

Let’s start with one of the biggest advantages of visiting Grand Teton in September, and the reason many people pick September: the changing of the landscape scenery with all the leaves turning a bright yellow, orange, and even some red, colors.

Put those colors in front of the Tetons – and click!stunning photos.

Add a light high-country snow dusting on the Tetons and you’ve hit the trifecta of fall scenery in Grand Teton National Park.

The turning of the leaves and fall colors is probably the biggest advantage for visiting in September. Especially if you are a photographer.

While fall foliage is a major draw for September visitors, the exact timing and intensity of the colors can vary from year to year.

The changing of the colors doesn’t happen all at the same time everywhere in the park. Elevation is a factor in when leaves start changing, and there are different elevations throughout the park.

Timeline of Leaves Turning in September

Historically, the timeline of trees changing color in Grand Teton in September is as follows*:

  • A few trees will start to change early in September, in higher elevations,
  • with the bulk of trees starting to change color mid-September,
  • coming on strong the third week of September,
  • with “prime” or “peak” time being the last week of September and the first week of October.*

*Note: This timeline is not a guarantee, this is an approximate timeline as the exact timing and intensity of the colors can vary from year to year. There can be “early” and “late” years, and even “brown” years (little color, straight to brown).

Pro Tip: If seeing fall colors is your priority for visiting Grand Teton in September, aim to visit in late September.

Pro Tip: Note the dates on all the photos in this article that show fall color – over the years it is usually end of September that have the strongest colors…

Fall Foliage Prediction Map

Smoky Mountain National Park provides an interactive map predicting when fall foliage will start and peak throughout the United States.

Please Note: that the Fall Foliage Prediction Map has the following disclaimer:

* The 2023 Fall Foliage Map is the ultimate visual planning guide to the annual progressive changing of the leaves. While no tool can be 100% accurate, this tool is meant to help travelers better time their trips to have the best opportunity of catching peak color each year. 

Oxbow Bend

Oxbow Bend is one of, if not the most famous places to photograph the fall colors in Grand Teton National Park.

Historically, Oxbow Bend is considered “prime” around the first week in October.

Pro Tip: If you want a shot from the edge of the parking lot, you will need to go hours before sunrise to claim a spot with your tripod. It will be COLD. Bring your hat, jacket, and gloves!

Pro Tip: There are other spots around Oxbow Bend besides the edge of the parking lot. Look for spots down by the water.

Pro Tip: If you want to see/photograph Oxbow Bend around its peak color – aim for the very end of September and/or the first week of October.

Advantage: Fewer People / Smaller Crowds

While summer sees a significant influx of tourists, September ushers in a quieter period in the park, especially after Labor Day as schools are back in session and most of the family travelers have left.

Note: The beginning of September can still experience a significant number of visitors through Labor Day as people try to take advantage of the last days of summer vacation.

Busy Places in Grand Teton National Park

And while there are fewer people in the park, the popular places in the park will still be….popular:

  • Jenny Lake
  • Hidden Falls
  • Taggart Lake
  • Laurance Rockefeller Preserve

Places like Jenny Lake will be among the busier places in September

Pro Tip: Still go early to the popular places to beat the crowds

Advantage: Cool, Crisp Weather

Honestly, the weather could be an advantage and a challenge.

Advantage

The days are cool and crisp – exactly how fall is described in every article ever…

But here, it really is true!

The air is drier here, so it really is crisp, and it’s the mountains in September, so the air really is cool.

Just know that 32 ºF in the morning is going to sting a bit.

You are going to feel it.

So definitely have your jacket, hat, and gloves. And definitely have a backpack to put those items in as the day goes on as it will be nice and warm, and you’ll need a handy place to keep shed layers.

While that description may not sound like an advantage – trust me, it is. You’ll understand when you get here. It feels as fall should (or as described to feel….).

Challenge

The “challenge” part of the weather is that September can have rain and thunderstorms and as the month goes on, you may even have chances of snow!

Snow can blow in and cause a white-out, blizzard condition, and even shut down roads for the day.

The funny thing is, that it can then melt off the next day and be completely sunny again with warm temperatures.

I tell you this not to scare you, but to prepare you that it can happen.

As long as you have warm clothing, jackets, hats, etc… you’ll be fine. And if a snow-in happens while you are here, just be willing to pivot or change plans for the day.

Note: Temperatures will be cold in the morning and evening, with warmer temps during the day. This may seem obvious, but seriously, some of those cold morning temps are rough!

Check the weather forecast: Daily Weather for Jackson Hole and Grand Teton National Park

Month Average High Temperature (ºF) Average Low Temperature (ºF) Average Rainfall (inches) Average Snow (inches)
May 61 ºF 31 ºF 2″ 2.4″
June 71 ºF 37 ºF  1.7″ 0.1″
July 81 ºF 42 ºF 1.2″ 0″
August 79 ºF 40 ºF 1.3″ 0″
September 69 ºF 32 ºF 1.4″ .4″
October 56 ºF 23 ºF 1.4″ 4.7″

 

Pro Tip: Carry a backpack to store layers. I carry one throughout the day so I always have what I need on hand and have a place to store what I don’t, and more importantly, I don’t waste time by having to go back to the car or campground.

Pro Tip: After rain and thunderstorms, the colors in the park are bright and vibrant. A good time and opportunity for stunning photos!

Advantage: Wildlife

In September, all wildlife are on the move for different reasons.

Some are preparing for the winter ahead packing on weight, and some are trying to ensure their species live on.

Elk, Moose, and Deer will be in their ruts* in September.

Grizzly Bears and Black Bears will be scrounging around consuming as many calories as they can.

Bison will be just finishing their rut at the end of August, the beginning of September.

BONUS: September is a great time to see bull moose as their antlers have fully regrown and they shed the velvet off them in early September.

Where to See Wildlife in September

Always keep a safe distance from wildlife. For your safety and the animals.

Give them their space, as they are even more agitated when needing to eat and/or breed. You don’t want to get in their way.

Note: Always keep a safe distance when viewing wildlife.

Whether you are in your vehicle or on foot, you must maintain a distance of at least 100 yards from bears and wolves, and 25 yards from all other wildlife.

Animals in the park are wild and may act aggressively if approached.

Pro Tip: Respect and follow instructions from the on-site Wild Life Management Teams. They are there to protect you and the animals. They are not trying to be “jerks” by asking you to stay in your car or move along. They really want you to see the animals, they know how thrilling that is! They just want to do everything possible to keep the animals safe and alive.

 

Advantage: Drier Hiking Trails at High Elevation

High-elevation hiking trails that might have been snow-covered or impassable earlier in the year are likely to be more accessible by September, as most of the snow has melted.

But, as we know from the weather section above, September can have sudden snow storms blow in, and if anywhere is going to get snow first, it is at the high elevations.

Therefore, it is important to check in with a ranger and/or visitor center and see what the latest conditions are and what, if any extra equipment is needed (possible ice axes and crampons).

Pro Tip: For drier high-elevation trails, go at the beginning of September. Snow is more likely in the high country as September goes on

In our experience, we always aim to do the Paintbrush – Cascade Canyon Loop (pictured above) in late August because it is less likely to have snow conditions that require ice axes and crampons…

Low Elevation Hikes

As for low-elevation hikes or front country hikes, trails should be in good condition, with the bonus of fewer people on them than in summer. The beginning of September usually mirrors the end of August conditions of being dry.

Do prepare your spirit that rain and/or snow may leave trails muddy with some standing water any time in September.

And of course, take all the proper clothing and items needed for the possibility of quickly changing conditions of snow and/or rain while on the trail.

Challenge: Services Closing

Grand Teton National Park is officially open 365 days a year and can be accessed any day of the year.

It is the roads, lodges, campgrounds, restaurants, services, and service providers that are not open year-round.

As the month of September goes on, more and more services and service providers pack up for the season.

Pro Tip: If you want to have all in-park services available to you, the beginning of September is best.

If you are coming towards the end of September to see the fall foliage at its peak (usually the last week of September to the beginning of October) be sure to check service providers’ closing dates – listed below.

Roads

Good news – all roads are open in September!

Usually, the only time a road is closed in September is if there is a lot of bear activity in that area.

For instance, sometimes the Moose-Wilson Road will be closed off if the bears are staying in the area to eat the Hawthorn berries that grow there.
