What to Wear in Melbourne in December
What to wear in Melbourne in December? With highs of 75°F and lows of 57°F, December opens Melbourne's summer season — warm and increasingly sunny, but with Melbourne's 'four seasons in one day' character fully re-engaged and summer heatwaves beginning in earnest by late December. About 9 rain days come as brief thunderstorms rather than sustained frontal rain. Light breathable layers with a compact jacket for cool changes cover the December range; sun protection is essential at St Kilda Beach and the Royal Botanic Gardens.
December in Melbourne is the arrival of summer — Christmas festivities in the CBD (Federation Square, Bourke Street Mall) combine with the beach culture returning fully to St Kilda and the bay foreshore, and the restaurant and rooftop bar scene operates at peak capacity on warm December evenings. Temperatures approach January's highs by month's end, and the risk of dramatic heat waves increases through December. The famous Melbourne cool change dynamic returns to full summer mode: a scorching 38°C day near the MCG can become a 60°F evening with a Southerly arrival. December dressing in Melbourne mirrors January's strategy — lightweight, breathable layers for the heat, with a thin windproof jacket always available for the cool change arrival that typically follows 2–3 days after a heatwave peak. St Kilda's beach and foreshore culture, the Yarra River outdoor dining scene, and the CBD's Christmas atmosphere all reward comfortable, smart-casual summer clothing with appropriate accessories for sun protection.

Frequently Asked Questions
What should I wear in Melbourne in December?+
Dress in light summer layers for Melbourne's December warmth: breathable linen or cotton shirts, lightweight shorts or trousers, and comfortable sandals or light sneakers. The 75°F average high is pleasant, but December heatwaves can push temperatures to 38°C+ by month's end near the MCG and Royal Botanic Gardens — pack accordingly. Always carry a thin jacket or cardigan for Melbourne's cool changes, which can drop temperatures by 15–20°C within hours on St Kilda beach evenings.
Is December a good time to visit Melbourne?+
December is an excellent time to visit Melbourne — Christmas in the city (Federation Square light shows, Bourke Street Mall decorations, outdoor events) is festive and crowd-friendly compared to Northern Hemisphere December tourism peaks. Summer beach culture at St Kilda returns, the restaurant scene is at full summer capacity, and the weather is predominantly warm and pleasant. The risk of extreme heat waves increases through December, but proper preparation and a cool-change jacket strategy makes the month highly enjoyable.
What shoes should I wear in Melbourne in December?+
Light sandals, leather slip-ons, or clean canvas sneakers are appropriate for Melbourne's December summer warmth. St Kilda beach and the exposed bay foreshore at Port Phillip are best navigated in sandals or water-resistant shoes on warm days. Melbourne's CBD laneways and rooftop bars retain the city's smart-casual footwear culture even in summer — clean leather sandals or quality sneakers fit both the beach and the laneway restaurant contexts comfortably.
How warm is Melbourne in December?+
December averages a high of 75°F (24°C) and a low of 57°F (14°C) — warm and increasingly summer-like, with heatwaves above 35°C (95°F) possible especially in the second half of the month near the MCG and the bay foreshore. Nine rain days come mostly as brief afternoon thunderstorms rather than the sustained frontal rain of winter. Melbourne's UV index in December is rated Extreme (11+) — one of the highest in the world and significantly more intense than comparable Northern Hemisphere summer destinations.
What should I pack for Melbourne in December?+
Pack light summer clothing: breathable shirts, shorts and lightweight trousers, sandals and light sneakers, and a compact umbrella for the 9 rain days. Critically, add a thin jacket for Melbourne's cool changes — the temperature drop at St Kilda beach and the Yarra River waterfront can be sudden and significant. SPF 50+ sunscreen, a wide-brim hat, and UV sunglasses are essential for outdoor December activities: Melbourne's December UV is extreme and burns unprotected skin in under 10 minutes at midday near Federation Square.
