🌟 Quick Answer: The Two Best Months for Route 66
If you're short on time and just want the magic formula:
✔️ May–June
Mild desert temps, wildflowers in the Midwest, long driving days, not peak-crowded yet.
✔️ September–October
Cooler Arizona weather, fall colors in Illinois, cheaper prices, golden photo light.
These two windows offer the best mix of comfort, weather, and crowds — ideal for first-timers.
📅 Season-By-Season Breakdown
Because Route 66 crosses 8 states and 2,448 miles, you can’t pick dates based on one region. Chicago weather has nothing in common with Arizona.
Let’s break it down so there are zero surprises when you start driving.
🌼 SPRING (March–June): The Best Overall Balance
If you want warm days, cool nights, and colorful scenery — spring is your season.
👍 Pros
- Comfortable temps in Arizona & New Mexico
- Wildflowers in Texas, Oklahoma, and Missouri
- Longer days make sightseeing easier
- Most attractions open for the season
👎 Cons
- Potential storms in Oklahoma & Missouri (April–May)
- Higher winds in the desert in early spring
Crowds: Moderate
Spring is the sweet spot before schools let out.
☀️ Photo Light: Clean, bright, colorful
The combination of spring bloom + neutral sunlight is perfect for photography.
🔥 SUMMER (July–August): Iconic, But Expect Extreme Heat
Summer is the “classic American road trip” vibe — but it also comes with intense challenges.
👍 Pros
- Longest days of the year
- All Route 66 attractions fully open
- Summer nights in small towns feel magical
👎 Cons (Read This Twice)
- Extreme heat in Arizona & New Mexico: 35–45°C / 95–113°F

- Higher hotel prices & more crowds
- Haze can reduce photo quality at midday
Crowds: Highest of the year
Families, international travelers, and bus tours = busy roadside stops.
☀️ Photo Light: Harsh midday, stunning sunrise/sunset
Plan important photo stops before 10 AM or after 6 PM for the best color.
💡 Pro Tip:
If your only available time is summer, drive early mornings and take a long lunch break during the hottest hours.
🍂 FALL (September–November): The Traveler Favorite
Fall is the golden hour of Route 66 season — literally and figuratively.
👍 Pros

- Fall foliage in Illinois & Missouri
- Fewer crowds

- Best sunsets of the year
👎 Cons
- Days shorten by mid-October
- Certain smaller attractions begin closing in early November

Especially after the September holiday rush.
☀️ Photo Light: Warm, golden, unreal
Vintage signs, neon, rusted cars — everything looks dramatic and nostalgic.
❄️ WINTER (December–February): Best for Experienced Road-Trippers Only
Route 66 is possible in winter, but you need to know what you’re signing up for.
👍 Pros
- Cheapest hotel rates of the year
- Zero crowds

- The desert looks incredible in winter light
👎 Cons
- Heavy snow in Illinois, Missouri, Kansas, and Oklahoma
