The main Australia cruise season lasts from October through March. Some ships sail the region year-round, but fewer itineraries are offered during Australia’s winter season of June through July. Most trips are between seven and 18 days in length, although longer sailings are available, and will also include stops at popular ports in New Zealand.
Australia’s seasons are opposite of those in the northern hemisphere, so when it’s winter in North America, Australia is right in the middle of its summer season. This is perfect timing for many travelers looking to escape cold weather at home or who would rather travel over the holidays, although many lines still offer cruises during Australia’s winter season to destinations with milder temperatures. For example, the average daytime temperature is 86 degrees in Darwin and 76 degrees in Port Douglas during June and July.
Overall, Australia’s climate varies considerably from windy, chilly and dry weather during the winter to hot, humid and very wet weather in the summer. It’s important to note that the seasonal temperature variation is greater in the southern parts of the country.
