Moab in September

Moab in September feels like a reward. The heat begins to ease, crowds thin compared with early fall peak, and the light softens. For many adventure travelers and photographers, Moab in September is the “just right” month.

Weather in September

Average highs drop to the low to mid 80s °F, with lows in the low 50s °F. Monsoon storms may linger early in the month, then taper off. Evenings become noticeably cooler and more comfortable.

Daylength shortens enough that sunrise and sunset feel less extreme, while still giving plenty of daylight.

• Hiking: Comfortable again for longer routes, especially with early starts.
• Driving: Roads mostly dry and in good condition.
• Photography: Warm, less harsh light and more tolerant temperatures.

What’s Open in September

Everything is open, but Arches remains regulated.

• Arches: Timed entry is in effect again from August 28 through October 31 between 7 am and 4 pm.
• Canyonlands: All districts open, very popular in September for both day hiking and backpacking.
• State parks and town: Full services, lots of tour options.

Crowd Levels in September

Moab in September is high but slightly more relaxed than October.

• Considered one of the best months to visit, thanks to moderate temperatures and fewer midsummer issues.
• Expect busy weekends, especially around events and holidays.
• Weekdays can be more manageable, though still lively.

Photo Plan for Moab in September

September is about softer heat and longer hiking options combined with excellent light.

Key September subjects

1. Early fall color at high elevations
   • The La Sal Mountains may show some early color that you can frame behind Arches scenes.
2. Warm canyon color
   • Lower sun angles bring richer textures and deeper shadow patterns to canyon walls.
3. Milky Way core in the evening
   • Early evening Milky Way sessions are still possible early in the month.

Daylight plan for Moab in September

• Sunrise:
  • Dead Horse Point or Island in the Sky for big canyon views.
  • Windows or Balanced Rock if you want to stay in Arches.
• Daytime:
  • Longer hikes such as full Devils Garden, Syncline Loop, or extended Needles routes are more reasonable in the cooler temperatures.
  • Use midmorning and midafternoon for hiking, resting midday if it is still warm.
• Sunset:
  • Delicate Arch, Grand View Point, or White Rim Overlook.
• Night:
  • Early in the month, plan one or two nights for Milky Way. Later in the month, transition to starry sky and constellation work.

Recommended gear

• Standard three lens kit (wide, midrange, telephoto)
• Tripod for sunrise, sunset, and night
