Spring is one of the best times to visit Rottnest Island if you want a balance of pleasant weather, wildlife and outdoor activities. Temperatures begin to rise, wildflowers appear across the island and summer crowds have yet to fully arrive.

  • Crowds: Moderate, generally increasing towards November.
  • Wildlife: Quokka joeys begin appearing, while migratory whales can be spotted offshore.

September is particularly good for spotting young quokkas, while October and November bring the island's wildflower season.

Summer: December to February

Summer is the busiest time to visit Rottnest Island and the best season for classic beach activities. Expect warm days, long daylight hours and lively island beaches, with an afternoon sea breeze often providing some relief from the heat.

Autumn: March to May

Autumn brings some of the most comfortable conditions for exploring Rottnest Island. Temperatures become milder after summer, crowds begin to ease and the island is well suited to active days outdoors.

  • Crowds: Moderate and generally lower than summer.

For travellers who want to explore more of the island rather than spend the whole day at the beach, autumn is a particularly good compromise between weather and crowds.

Winter: June to August

Winter is the quietest season on Rottnest Island, but that doesn't mean there is less to do. Cooler temperatures make walking and cycling more comfortable, while winter rain brings new growth to the island's landscapes.

Best for: Hiking, cycling, photography, wildlife and a quieter island experience

Quokkas live on Rottnest Island throughout the year, so there is no bad season for a quokka encounter. They are naturally most active around early morning and late afternoon, when temperatures are cooler.

For a particularly memorable wildlife experience, visit between August and September, when young quokkas may begin emerging from their mothers' pouches. Spring also brings increased birdlife and whale sightings around the island.

Whales can be spotted around Rottnest from August to December, with occasional sightings as early as June or July. Look for them from coastal viewpoints around West End or even during your ferry journey.

Because Rottnest is car-free, cycling is one of the most convenient ways to explore beyond the main settlement.
