What to wear in the Dandenongs (it's colder than the city)

Why it's genuinely cooler up there
The Dandenong Ranges rise to around 633 metres at Mount Dandenong, and the general rule for this part of Victoria is that temperatures drop roughly a degree for every 150 metres of elevation gained — meaning the Belgrave area can run a noticeable few degrees cooler than central Melbourne on the same day, typically in the order of two to five degrees. Add the shade of tall mountain ash forest and the wind on an open train carriage, and 'take a jacket even if the city forecast looks mild' is genuinely practical advice, not caution for its own sake — it's the single most common gap between what visitors pack and what the day actually needs.
Dressing for the train
If you end up in one of the open-sided carriages, you're exposed to whatever wind the train's own motion creates, on top of the ambient forest temperature — cooler again than simply standing on the platform. A layer that's easy to put on and take off works better than a single heavy coat, since Belgrave to Emerald Lake is a short enough ride that conditions won't change dramatically, but the wind-chill while moving is real.
Dressing for the sanctuary
Healesville Sanctuary is an outdoor, path-based site with limited indoor shelter, so plan for the weather rather than assume you'll duck inside if it turns cold or wet. Three hours of walking rewards comfortable, broken-in closed shoes over anything you'd only wear for a short city outing.
The rest of the day
Melbourne's own weather can shift within a single day regardless of what the Dandenongs are doing, so layers that work in the city in the morning and in the hills by midday are the safer bet than committing to one outfit for eight or nine hours. A compact rain layer is worth having regardless of season — this is a temperate rainforest region, and showers don't always announce themselves.
Seasonal swings worth knowing about
Victoria's seasons run roughly opposite to the northern hemisphere's: December to February is Melbourne's summer, and the Dandenong Ranges can still run warm on a hot inland day, while June to August is genuinely cold and occasionally wet enough to matter for an open train carriage. Australian summers also bring a real bushfire-season awareness across forested parts of Victoria, including the Dandenongs — it rarely affects a scheduled day tour, but it's part of why forest-fringe attractions here take fire safety seriously on days of extreme heat and wind, and why a tour could occasionally be affected on the worst of those days.
Why the forest itself holds moisture and cold
The mountain-ash and tree-fern gullies the line runs through are classified as temperate rainforest, which means the canopy and undergrowth hold both shade and damp air even when it hasn't rained recently. That's part of what makes the Dandenongs feel several degrees cooler than the surrounding open country, and it's worth factoring in even on days when Melbourne's own forecast reads mild and dry.
At the sanctuary specifically
Healesville Sanctuary's paths are mostly uncovered, so sun protection matters on a clear day just as much as a jacket matters on a cold one — a hat and sunscreen are worth packing alongside the layers, especially given the three hours you're likely to spend there. The Yarra Valley sits in more open country than the Dandenongs, so it can genuinely feel warmer at Healesville than it did an hour earlier at Belgrave, which is one more reason to dress in layers rather than for a single expected temperature.
