Australia (Sydney) – What you should know
Sydney lies at latitude 34°S — climatically comparable to the Mediterranean but with reversed seasons. While Europe has winter, Sydney is in full summer. Summers are warm and at times humid (typically 22–26°C (72–79°F)), occasionally interrupted by heatwaves above 40°C (104°F). Winters are mild and pleasant (9–17°C (48–63°F)).
A characteristic element of Sydney's weather is the "Southerly Buster": a powerful southerly wind that sets in suddenly after heat periods and can cool temperatures by 10–15 degrees within hours. Weather apps are therefore essential when visiting Sydney.
The best travel time for Sydney is September to November (the Australian spring): pleasant temperatures, the jacaranda trees bloom in a sea of purple, and the city emerges from winter. December and January lure with beach and summer, but are also the most expensive and busiest travel time.
