St Arnaud is seeing a partly cloudy afternoon with temperatures hovering around the mid-twenties Celsius, according to the live forecast above, as a light northerly drift keeps conditions dry across the Northern Grampians district.
How will the next few days shape up?
A weak trough will brush through on Wednesday, bringing a 30% chance of a light shower, but nothing heavy. Thursday and Friday return to mostly sunny skies, with daytime highs staying near 28°C. Overnight lows will dip to around 12°C, so mornings feel fresh. The St Arnaud weather radar shows no significant storms on the horizon.
What makes St Arnaud’s weather distinctive?
Nestled at the foot of Mount Bolangum, St Arnaud experiences a classic north-central Victoria climate — warm summers, cool winters and the occasional frost. Because it sits inland, away from the coastal influence, temperature swings are more pronounced than in places like the Melbourne weather zone. Those considering St Arnaud real estate often note the reliable dry season and relatively low humidity.
Does St Arnaud get snow?
Snow in St Arnaud itself is very rare — the lower elevation keeps things above freezing most winter nights. The surrounding ranges may see a light dusting once or twice a decade, but it never lasts long.
What is the best time to visit?
Spring (September–November) and autumn (March–May) offer mild days and clear nights. Summer can be hot, with January temperatures occasionally cracking 35°C, while winter brings chilly mornings and patchy fog.
How reliable is the St Arnaud weather radar?
The radar covers a 200 km radius and gives good short-term warnings for approaching fronts. Terrain near the Grampians can create minor shadow zones, but for most purposes it’s accurate. Check Elders Weather St Arnaud for localised updates.
