Average Temperatures in September
September in Sedona is generally warm but not as brutally hot as the peak summer months of June through August. The average high temperature during the day hovers around 88°F to 92°F (31°C to 33°C), while the average low in the evening drops to about 58°F to 63°F (14°C to 17°C). These numbers make September a comfortable month compared to July, when highs regularly exceed 100°F It's one of those things that adds up..
The temperature gradually begins to cool as the month progresses. Early September can still feel like summer, with occasional days pushing into the mid-90s. By late September, you'll start noticing more consistent cooling trends, and some mornings may feel crisp with temperatures dipping into the 50s.
Here's a quick breakdown of typical daily temperatures:
- Early September: Highs 90–93°F, Lows 60–63°F
- Mid September: Highs 87–90°F, Lows 58–62°F
- Late September: Highs 84–88°F, Lows 55–60°F
These averages come from long-term climate data recorded at Sedona's local weather stations. Of course, actual conditions can vary based on elevation, cloud cover, wind, and other factors.
Daily Temperature Fluctuations
One of the most notable characteristics of the temperature in Sedona AZ in September is the dramatic difference between daytime and nighttime temperatures. And because Sedona sits at an elevation of roughly 4,350 feet (1,326 meters), the air cools significantly once the sun goes down. On a typical September day, you might start your morning hike in a light jacket, enjoy warm sunshine by noon, and then reach for that same jacket again as the desert cools after sunset.
This diurnal temperature swing is something every visitor should prepare for. The desert sun can be intense during the day, especially if you're hiking or spending time outdoors without shade. UV index levels remain high in September, so sunscreen, a hat, and plenty of water are essential. Then, as evening rolls in, temperatures can drop 30 to 40 degrees in just a few hours.
Pro tip: If you're staying in a vacation rental or hotel, avoid booking rooms without climate control. Even though nights are cool, some properties rely on natural ventilation alone, and you may wake up feeling chilly.
Weather Patterns and Conditions
September in Sedona is generally dry, with very low humidity. Rainfall is minimal during this month, averaging less than 0.5 inches for the entire month. You might see a passing afternoon shower or a brief monsoon storm, but these are uncommon and usually short-lived Worth keeping that in mind..
Honestly, this part trips people up more than it should.
The sky conditions are often clear to partly cloudy, giving visitors stunning views of the red rock formations bathed in golden afternoon light. Wind is typically light, though gusty conditions can occur in exposed areas like ridgelines or near the higher elevation trails It's one of those things that adds up..
One weather phenomenon worth noting is the monsoon season, which in Arizona traditionally runs from mid-June through September. While monsoon activity tapers off by September, isolated thunderstorms are still possible, especially in the first half of the month. These storms can bring sudden temperature drops, brief heavy rain, and even lightning. If you're on a hike or outdoor activity, keep an eye on the sky and head back to shelter if storms develop.
How September Compares to Other Months
To put September in context, it helps to compare it with the surrounding months:
- August: Often the hottest month, with highs averaging 95–100°F. Very dry heat.
- September: Warm but manageable, highs 84–92°F. Ideal for outdoor activities.
- October: Cooler, highs 75–82°F, lows 48–55°F. Beautiful fall colors may begin to appear.
- November: Colder, highs 65–72°F, lows 38–45°F. Some early snow possible at higher elevations.
September serves as a perfect transition month. It's warm enough to enjoy swimming in Oak Creek, but cool enough that you won't feel overwhelmed by the heat. Many longtime Sedona visitors consider this one of the best months to visit for exactly this reason.
What to Wear and Pack
Packing for Sedona in September requires a bit of strategy because of the wide temperature range. Here's a recommended packing list:
- Light layers: T-shirts and shorts for the day, but bring a fleece, hoodie, or light jacket for evenings and early mornings.
- Sun protection: Wide-brimmed hat, sunglasses, and SPF 30+ sunscreen are non-negotiable.
- Sturdy hiking shoes: If you plan to explore trails like Cathedral Rock, Bell Rock, or Devil's Bridge, proper footwear is essential.
- Water bottle and hydration gear: The dry climate means you'll lose fluids faster than you realize.
- Light rain jacket: Just in case a brief monsoon shower rolls through.
Avoid packing heavy winter clothing. While nights can be cool, they rarely get cold enough to require anything more than a mid-weight layer Which is the point..

By this point, the extreme summer heat has eased, the monsoon season is winding down, and the weather settles into a reliable pattern of warm days and cool nights.
