Perth

Spring (Sep–Nov): Mild 15–25°C, blooming wildflowers in Kings Park and throughout WA. Shoulder season—comfortable sightseeing, fewer crowds and moderate prices. Summer (Dec–Feb): Hot and sunny 25–38°C with cooling sea breezes; best for beaches, Rottnest and watersports. Peak season (school holidays, Christmas/New Year). Major events: Fringe World (Jan) and Australia Day (Jan 26). Autumn (Mar–May): Warm, pleasant 18–28°C and fewer tourists—ideal for walking, vineyards and day trips. Late-Feb/Mar arts programming (Perth Festival) often overlaps early autumn. Winter (Jun–Aug): Cool 8–18°C with more rain; true off-peak—lower fares and hotel rates. Great time for whale-watching along the coast (June–Sept) and indoor cultural venues.
