Check the live forecast above before heading out to Mambourin – this western Melbourne suburb often feels a few degrees cooler than the city centre thanks to its exposure to Port Phillip Bay breezes, making layering your best bet for comfort.
What’s the typical weather in Mambourin?
Mambourin shares a temperate oceanic climate with nearby Werribee and the broader Geelong region. Summers (December–February) are warm but rarely extreme, with average highs around 25–28°C, while winters (June–August) are cool and damp, with daytime temperatures hovering near 14°C and frequent rain. Spring and autumn offer the most stable conditions for outdoor plans – clear skies and mild temperatures make those seasons the pick of the year for a visit.
What should you pack for Mambourin?
Pack a light jacket or cardigan even in summer – the afternoon sea breeze can drop temperatures quickly. For winter trips, bring a waterproof coat, sturdy shoes and a warm jumper. If you’re visiting during Victorian school holidays (late September or early July), layered clothing and an umbrella will cover the changeable spells. The value play is to come in spring (October–November): accommodation is cheaper, crowds are smaller, and the weather is reliably fine for exploring nearby Werribee Open Range Zoo or the You Yangs.
