At the tail end of summer, Phoenix is a laid-back and relaxed city, but it's also very hot, especially during the day. Nighttime offers some relief, but you'll probably want to make sure you'll have access to a pool at some point during your visit. Events are few and far between, but pockets of cooler weather should inspire you to explore the outdoors. Phoenix can experience some severe weather too, so try to stay on top of the weather reports and during your visit.

Phoenix Weather in September

Monsoon season in Arizona runs from June through September and brings with it the risk of flash floods and dust storms. Flash flooding can cause inconvenient road closures and dust storms can lead to dangerous driving conditions due to low visibility. One bright side of monsoon season is that it offers a chance of rain, which is a welcome relief for locals, but if you’re visiting from an area where storms are the norm, it's unlikely to impress you.

You'll have to wait until November for summer to give up its hold on the city. In September you can expect average high temperatures of 100 degrees Fahrenheit (38 degrees Celsius) an average lows of 77 degrees Fahrenheit (25 degrees Celsius).

What to Pack

Even though it's hot, you'll want to bring a light jacket on your trip to Phoenix. Nighttime can be cold in the desert and daily highs can vary somewhat drastically, while hotels and businesses are still going to be cranking the air conditioning. Light, breathable fabrics that protect from the sun are also a must. If you'll be spending a lot of your time outside, consider sunny-weather essentials a must-pack: hats, sunglasses, sunscreen, bathing suit, etc.
