September in Australia

September is Australia’s first month of spring, the season that allows Mother Nature to really show off. It is the most popular month in the country for weddings and also tends to be a peak travel period, particularly around the school holidays.

It is a large country with a variety of climates, but most of Australia has four seasons, which land at opposite times to those in the northern hemisphere. Here, September to November is spring. If you are seeking a ski trip, you'll want to head south, but if you are hoping for a beach vacation and warmer days, the north will be your destination. Outdoor activities like walking tours, waterfalls, hiking, hot air ballooning, and other sports are all possibilities on your September trip to Australia. It's also a great time for also attending the many flower events held all over the country, along with arts and cultural festivals.

Australia Weather in September

Unless you're traveling to the more tropical north or the snowy mountains, Australia has mostly temperate spring weather that is neither hot nor cold, though nights are a bit cooler. Average highs and lows in major cities outside of Queensland and the Northern Territory are pleasant.

  • Average high: 68 degrees Fahrenheit (20 degrees Celsius)
  • Average low: 50 degrees Fahrenheit (10 degrees Celsius)

Rain at this time is generally light and infrequent, with average rainy days ranging from two per month in the Northern Territory to 12 in Ballarat, Victoria, and Bunbury, Western Australia.

What to Pack

As you prepare for a trip to Australia, how you fill your suitcase depends on where you are going, though you will generally find mild weather. Layering clothing works well to cover your bases. Also, check the weather forecasts before you go to plan accordingly.

  • If you are going somewhere warm, bring along T-shirts or lightweight shirts, shorts, skirts, a jacket for cooler evenings, swimsuits, and comfortable shoes. You'll probably also want to have sun protection from hats to a sun umbrella to sunscreen.
  • For tropical areas, it's helpful to have some mosquito repellent and breathable clothing.
  • If a cooler destination is in mind, you'll want long pants and long-sleeved shirts, a sweater/jacket, comfortable closed-toe shoes, and the like.

September Travel Tips

  • Traveling to Australia during the spring is usually cheaper and less crowded, so it's a good time to explore. However, during school holidays, which are usually from late September to the middle of October, you may find yourself competing and paying a premium for flights and accommodations, so keep this in mind before booking and plan in advance.
  • Australia has no public holidays during September, so closings and limited hours shouldn't affect your activities or travel schedules.
  • Keep in mind the country is huge—the sixth-largest in the world—and unless you have months to spare, it's not easy to see everything in one trip, so take as much time as you can to enjoy each stop.
