Today in London, Ontario, the live forecast above shows mild conditions with a mix of sun and cloud, though a few afternoon showers are possible. Temperatures sit near seasonal norms for early autumn, making for a fairly typical October day across southwestern Ontario.
What will the rest of the day look like?
The morning starts partly sunny, but cloud cover will thicken by midday as a weak system drifts through the region. The live forecast indicates peak warmth in the mid-afternoon, then a slight cooling trend as the chance of rain increases toward evening. Winds remain light and variable, so it stays comfortable for errands or a short walk — just keep an umbrella handy if you’re out past supper.
How does today compare to seasonal averages?
London’s early-October weather often sees highs in the mid-teens Celsius, and today fits that pattern. The live forecast shows readings a degree or two either side of normal, with no extremes in either direction. This kind of quiet day is typical before the next stronger front arrives later in the week — a good chance to enjoy the calm before the weather pattern shifts.

Should I expect any weather warnings today?
No widespread warnings are currently posted for London. The live forecast shows only a modest chance of showers, and Environment Canada’s alert page remains clear. Still, it’s wise to check before heading out, especially if you’re driving later.
What time will the sun set in London today?
Sunset times shift quickly this time of year. The live forecast includes precise sunrise and sunset data — generally, London’s evening twilight ends around 7:00 p.m. EDT in early October.
Is this a good day for outdoor plans?
It depends on timing. Morning and early afternoon are fine for a walk or bike ride, but the rain chance increases after 3 p.m. If you’re flexible, aim for a midday outing, and keep an eye on the live forecast for any last-minute changes.
