Peak season & crowds
Sydney is busiest — and accommodation priciest — over the December–January summer school holidays around Christmas and New Year, plus long weekends and major events. For thinner crowds and better value, the autumn (March – May) and spring (September – November) shoulder seasons are the sweet spot — mild weather without the peak-season squeeze.
