Visiting the USA in September: Weather, Events & Travel Tips
September is one of the best months to visit the USA if you’re flexible about exact timing. The summer holiday crowds clear after Labor Day (the first Monday of September), hotel rates drop, and the weather across most of the country remains genuinely warm without the punishing heat of July and August. The first fall foliage appears in northern New England by mid-month. Hurricane season remains active on the Atlantic and Gulf coasts through the end of September.
Weather by Region
| Region | Avg High | Avg Low | Rainfall | Notes |
|---|---|---|---|---|
| Northeast | 23°C (73°F) | 13°C (55°F) | 85mm | Pleasant; fall colour begins in Vermont and Maine by late month |
| South | 31°C (88°F) | 20°C (68°F) | 110mm | Still hot and humid; hurricane risk through late September |
| Midwest | 24°C (75°F) | 12°C (54°F) | 75mm | Comfortable; lake temperatures still swimmable early month |
| Southwest | 33°C (91°F) | 18°C (64°F) | 20mm | Monsoon ends; temperatures begin to ease — ideal for Grand Canyon hiking |
| West Coast | 22°C (72°F) | 13°C (55°F) | 8mm | Warm and clear; low wildfire smoke risk in northern California varies by year |
The shoulder season shift after Labor Day is real and measurable. A hotel room in New York City that costs $350/night in August typically runs $220–$270/night in mid-September. The same drop applies in Chicago, Boston, and most coastal cities.
The Southwest becomes significantly more viable in September. Hiking the Grand Canyon’s Rim-to-Rim trail or the Angels Landing trail in Zion carries genuine heat risk in July and August; September mornings are manageable, though still warm.
Major Events in September
Labor Day Weekend — Nationwide, first Monday of September Not an event in itself, but the long weekend (Saturday through Monday) generates travel surges equivalent to Independence Day. Prices spike for that specific weekend, then drop sharply. If possible, arrive Tuesday after Labor Day for the best combination of good weather and low prices.
New Orleans Saints & NFL Season Opener — Nationwide, early September The NFL regular season kicks off in September. For a full stadium experience, any team’s home opener is worth considering — but New Orleans (Caesars Superdome, 1500 Sugar Bowl Dr) offers the most atmospheric crowd, and the city itself makes the trip worthwhile regardless of the game. Tickets from approximately $80 on the secondary market; premium seats from $200+.
Oktoberfest USA — La Crosse, Wisconsin, late September Riverside Park. One of the largest Oktoberfest celebrations outside of Munich, running since 1961. Free admission to the park; beer gardens from approximately $5–$8 per stein. La Crosse is a scenic river city on the Mississippi that few international visitors reach — which is part of the appeal.
Austin City Limits Music Festival — Austin, Texas, first and second weekends of October (but tickets go on sale in September) Zilker Park. Three days per weekend, with the same lineup repeated twice. Weekend passes from approximately $295; single day from approximately $115. September is the time to buy — tickets sell fast after the lineup announcement.
Monterey Jazz Festival — Monterey, California, late September Monterey Fairgrounds, 2004 Fairground Rd. Running since 1958, one of the longest-running jazz festivals in the world. Weekend passes from approximately $175; single day from approximately $70. Monterey in late September is mild and foggy in the mornings, clearing to sunshine by midday.
City Recommendations
Vermont (Stowe and Burlington)
For foliage, Vermont is the primary destination — and September visitors catch the very beginning of the colour change in the higher elevations around Stowe. Peak colour typically falls in early October in southern Vermont; late September in the north.
Where to stay: Stowe Mountain Lodge (7412 Mountain Rd, Stowe) for a full-service resort experience; from approximately $280/night in September, rising steeply through October. In Burlington, the Hotel Vermont (41 Cherry St) is the city’s best property; from approximately $220/night.
Where to eat: Hen of the Wood (92 Stowe St, Waterbury) is Vermont’s most consistently acclaimed restaurant — local sourcing taken seriously, not performatively. Mains from approximately $28. For a more casual stop, Al’s French Frys (1251 Williston Rd, Burlington) is a local institution serving crinkle-cut fries since 1948.
Seattle, Washington
September is Seattle’s best month. Summer fog burns off, rainfall is minimal, and the Cascade Mountains are accessible and snow-free. Mount Rainier National Park is at its clearest.
Where to stay: The Kimpton Hotel Monaco (1101 4th Ave) is central and well-equipped; from approximately $180/night in September. The Edgewater Hotel (2411 Alaskan Way) sits over Elliott Bay and has views that justify the higher rate — from approximately $280/night.
Where to eat: Canlis (2576 Aurora Ave N) for the occasion dinner — Pacific Northwest fine dining at its most committed; prix-fixe from approximately $145/person. For something more accessible, Manolin (3621 Stone Way N) serves excellent seafood in a relaxed Fremont setting; mains from approximately $22.
Sedona, Arizona
After the punishing summer, Sedona becomes genuinely hike-able in September. The red rock formations are best photographed in the warm morning light, and evening temperatures drop to a comfortable 18–20°C.
Where to stay: Enchantment Resort (525 Boynton Canyon Rd) for the full canyon immersion; rates from approximately $450/night but drop from peak July rates. The El Portal Sedona (95 Portal Ln) is smaller and more characterful; from approximately $280/night.
Where to eat: Elote Cafe (771 Hwy 179, King’s Ransom Hotel) for Southwestern cooking that consistently outperforms its tourist-town location; shared plates from approximately $14. Book at least two weeks ahead.
Packing List for September
Clothing
- Layering is essential in September — mornings can be 13°C, afternoons 25°C, especially in the Northeast and Midwest
- Light jacket or fleece for evenings in New England and the Pacific Northwest
- Short sleeves and shorts still appropriate for daytime in most regions
- One waterproof outer layer — rain is possible in the Northeast and Pacific Northwest
Footwear
- Solid walking shoes suitable for urban and light trail use
- Hiking boots if visiting national parks (Zion, Grand Canyon, Mount Rainier)
Sun Protection
- Sunscreen still necessary, especially in the Southwest and at altitude
- Sunglasses
Practical
- Portable battery pack
- Insect repellent — mosquitoes and ticks remain active through September, especially in the Northeast and South
- Reusable water bottle; hydration still matters in desert environments
Health
- Antihistamines — ragweed peaks in September across the Midwest and Northeast; it is one of the highest-pollen months of the year in those regions
- Any prescription medications in carry-on luggage; US pharmacies require local prescriptions for most drugs
Booking and Budget Notes
The post-Labor Day rate drop is real but not universal. Premium hotels in New York, San Francisco, and Chicago may keep rates elevated through mid-September due to convention and business travel resuming. Check rates for the specific dates rather than assuming a blanket discount.
Fall foliage tourism in Vermont and western Massachusetts books out quickly — if peak colour (typically early-to-mid October) is your target, make accommodation reservations by August. The foliage season is intensely regional and year-to-year timing varies; the Vermont Foliage Tracker at foliage.vermont.gov publishes weekly updates.

Frequently Asked Questions
- Is September a good time to visit the USA?
- September is one of the best months to visit — summer crowds clear after Labor Day (first Monday of September), hotel rates drop significantly, and weather across most of the country remains genuinely warm. A NYC hotel room that costs $350/night in August typically runs $220–270/night in mid-September. The Southwest also becomes viable again for hiking after summer's extreme heat.
- When does fall foliage start in the USA?
- The first fall foliage appears in northern New England (Vermont, Maine) by mid-to-late September at higher elevations. Vermont's foliage tracker (foliage.vermont.gov) publishes weekly updates. Peak colour in southern Vermont typically falls in early October; the display advances northward as the season progresses. Book accommodation in Vermont foliage towns (Stowe, Woodstock) by August.
- How much do hotel prices drop after Labor Day?
- The post-Labor Day rate drop is real and measurable. Major cities see 15–30% drops in hotel rates after the first Monday of September compared to August. The exception is convention and business travel — premium hotels in New York, San Francisco, and Chicago may keep rates elevated through mid-September as the business travel calendar resumes.
- Is the Grand Canyon crowded in September?
- The Grand Canyon's South Rim remains busy in early September but becomes more manageable from mid-month onward. September mornings in the canyon are genuinely hikeable — temperatures are still warm but not the brutal 110°F+ of summer. Check current timed entry requirements at the NPS website before visiting.
