How does Sunbury’s geography affect its weather?
The town sits on the volcanic plains at the foot of the Macedon Ranges. This position means cold air drains downhill on clear nights, often leading to fog. During summer, northerly winds can bring very hot conditions, while southerly changes offer sudden relief. The nearby ranges also trigger localised showers, especially in spring.
