Sydney summer days are hot and the sun is fierce, but unlike Brisbane or the Gold Coast, Sydney is not humid or muggy. People wear shorts, T-shirts, light cotton or linen dresses, a cap or a wide-brimmed hat and sunglasses. The evening sea breeze and strong indoor air-conditioning mean locals always carry a light jacket, a long-sleeved shirt or a thin cardigan.

Winter is mild and snow-free, but early mornings and evenings are cold. The rule of an Australian winter is layers. Jeans, sneakers and a T-shirt with a warm jumper or hoodie are comfortable by day. For mornings and evenings bring a light jacket, a puffer, a trench coat or a windproof jacket, and a scarf against the cold ocean wind.
🍂🌱 Autumn (March to May) and spring (September to November)
days 20–25 °C (68–77 °F)
The in-between months are changeable: a summery afternoon can turn cold by evening. Wear a short-sleeved T-shirt, but always take a jumper, a light windbreaker for the evening and an umbrella for a sudden shower.
