Sunscreen, a hat, and sunglasses are mandatory attributes for Australia at any time of the year.

In the cooler months, especially in winter (from June to August), when the average temperature holds at 11-12°C and the minimum can drop to 7-8°C, warmer clothing will be required. Bring sweaters, fleece jackets, jeans or thick trousers, and a warmer jacket, preferably windproof, as coastal areas can be breezy. In autumn (March-May) and spring (September-November), the weather in Wollongong is changeable: from cool to moderately warm. The best strategy would be layering your clothes: a t-shirt, a light sweater or cardigan, and a windbreaker or light jacket will allow you to feel comfortable with temperature changes throughout the day. Regardless of the season, comfortable walking shoes are essential to fully enjoy the beauty of the city and its surroundings.
