☀️ Summer (December, January, February)

30–32 °C (86–90 °F)

Perth summers are very hot, dry and sunny. Wear the lightest breathable cotton and linen: shorts, singlets, light sundresses. The sun is very strong, so a cap or bucket hat and sunglasses are a must. Warm clothes are hardly needed, apart from a thin shirt for air-conditioned rooms.

❄️ Winter (June, July, August)

days 18–19 °C (64–66 °F)nights 8 °C (46 °F)

Winter is mild but it is the rainy season. Locals switch to jeans, sneakers, long-sleeved tops and hoodies, with a waterproof windbreaker or light jacket and an umbrella always at hand.

🍂🌱 Autumn and spring

20–25 °C (68–77 °F)

A very comfortable time. Summer clothes are fine by day; for the evening, when the fresh sea breeze comes in, a light cardigan, a denim jacket or a thin jumper is enough.
