Tripsavvy's Editorial Guidelines Courtney Kellar Updated 09/20/20 Share Pin Email ImagineGolf / Getty Images 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. Monsoon Season 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. Phoenix Weather in September You'll have to wait until November for summer to give up its hold on the city, as September temperatures have reached as high as 116 degrees Fahrenheit (47 degrees Celsius) in Phoenix. Average high: 100 degrees Fahrenheit (38 degrees Celsius) Average low: 77 degrees Fahrenheit (25 degrees Celsius) September averages less rain (0.64 inches) than July and August (about 1 inch apiece), but it can still come in bunches. 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, including hats, sunglasses, sunscreen, and a bathing suit. September Events in Phoenix At the end of summer, the city of Phoenix still has a few events rolled up its sleeves. However, in 2020 many of these events may be canceled or postponed, so be sure to check the organizers' official websites for the latest updates.

SanTan Oktoberfest: Every September, you can kick off fall with pretzels and lager at this local Phoenix brewery that hosts an annual party for Oktoberfest. Attend a Sporting Event: If there are two things Phoenix locals love in September, it’s sunsets and sports. The MLB’s Arizona Diamondbacks and the NFL’s Arizona Cardinals both play in closed stadiums, while the Arizona State Sun Devils football team and Phoenix Rising Football Club both play in outdoor stadiums with striking sunset and mountain views. In 2020, no fans are allowed at any Major League Baseball games, and the Cardinals have closed State Farm Stadium for both of team's September games. The Sun Devils and the rest of the Pac-12 have delayed the start of the conference season until after September 2020, but the Phoenix Rising reopened Casino Arizona Field on September 11.
