Summer (December to February, peak season) is warm and dry, with average temperatures around 29°C (84°F) and plenty of sunshine. Sea breezes keep afternoons comfortable, and long evenings are ideal for beach days, outdoor dining, and open-air events along the river and coast.
Autumn (March to May, shoulder season) brings mild days around 22°C to 26°C (72°F to 79°F) and cooler nights. It is a pleasant time for walking in Kings Park, exploring neighbourhoods on foot, and enjoying wine-tasting trips in the Swan Valley with fewer crowds and clear, stable weather.
Winter (June to August, low season) is cooler and wetter, with average temperatures near 18°C (64°F). Showers are interspersed with bright, crisp days that suit museum visits, markets, and coastal walks. You can enjoy quieter attractions and cosy cafes while still making the most of Perths outdoor spaces.
Spring (September to November, shoulder season) sees temperatures rising to around 22°C to 25°C (72°F to 77°F) and clear, sunny skies. Wildflowers bloom in parks and nearby regions, and comfortable conditions make it an excellent time for cycling, river cruises, and day trips before the heat of summer.
