What makes Fergus weather different from nearby cities?
Fergus lies in Wellington County, roughly 20 km north-west of Guelph, at an elevation of about 400 metres. Its position downwind of the Great Lakes means winter snow totals are often higher than in Toronto, while summer thunderstorms can form quickly when warm, humid air meets the local escarpment. The live forecast above will show you the immediate conditions, but for a broader view, the Canada weather hub links to regional radar and warnings.
How reliable are longer-range forecasts for Fergus?

Beyond that, small shifts in lake-effect patterns can change snowfall predictions by 5–10 centimetres. The fergus weather hourly breakdown and fergus weather radar loops on The Weather Network’s fergus weather network page help you track those changes in real time.
