Check the live forecast above for your 10-day outlook in London, Ontario, as conditions shift frequently with Great Lakes influence. Plan layers and a rain jacket this week, as temperatures will vary day to day.
What will the temperature and precipitation be like over the next 10 days?
Daytime highs will range from the low single digits to the mid-teens Celsius, while overnight lows drop near or slightly below freezing. Expect a mix of sun and cloud, with at least one or two rainy periods driven by systems moving east from Lake Huron. Snow is unlikely in the 10-day window, but a few flurries are possible early in the period if cold air lingers.
How does Lake Huron affect London’s 10-day forecast?
London sits downwind of Lake Huron, so lake-effect cloud bands can bring extra cloud cover or light rain in the first few days. This effect weakens as the lake cools, but it still makes the forecast less predictable than inland cities. Check the live forecast above for hourly updates.
