Check the live forecast above before heading out in Sudbury today, as lake-effect conditions off Georgian Bay can shift conditions quickly across the city and into the outlying communities of Valley East and Lively.
What is the weather like in Sudbury right now?
The live forecast above gives you the current temperature, wind, and precipitation odds for Greater Sudbury. Because the city sits inland on the Canadian Shield, expect cooler nights even in summer, and lake-effect snow squalls off Georgian Bay during winter months that can reduce visibility along Highway 69 south.
What should I expect for the week ahead?
For the next few days, the live forecast above shows the trend. Sudbury weather 7 days often follows a pattern of clearing after a cold front passes, then a gradual warm-up midweek. If you are checking the weather network Sudbury 7 day, remember that the city’s elevation near Ramsey Lake can mean a few degrees cooler than the official airport reading.
Frequently asked questions
Where can I find a Sudbury weather 14 day or 30-day forecast?
Long-range outlooks are available from Environment Canada and The Weather Network. For Sudbury weather 30-day forecast trends, check the live forecast above and the sources below; beyond 10 days, confidence drops sharply for northern Ontario.
How does lake-effect snow affect Sudbury?
When cold air crosses the relatively warm waters of Georgian Bay, it picks up moisture and dumps heavy snow on the south side of the city. This can make the weather in Greater Sudbury 10 days look very different from what falls in the northern neighbourhoods near Lake Wanapitei.
Is Sudbury weather linked to local news or obituaries?
Yes — severe weather events often appear in Sudbury news coverage, and winter storm warnings can delay funeral services listed in Sudbury obituaries. For active alerts, see our Weather Warning page.
