Check the live forecast above for London Ontario’s hour-by-hour conditions today. Temperatures climb through mid-morning, then a chance of afternoon showers arrives as a weak cold front slides across southwestern Ontario. Plan outdoor errands before lunch.
What will the hourly weather look like in London today?
The live forecast above shows a mostly cloudy morning with temperatures rising steadily from the low teens into the mid‑20s by early afternoon. A band of scattered showers is likely between 2 p.m. and 6 p.m., followed by clearing and a cooler evening. Winds stay light out of the southwest, picking up slightly near the lake.
How does Lake Huron influence London’s hourly readings?
London sits inland from Lake Huron, so afternoon lake breezes can knock a couple of degrees off the hourly high when the wind shifts off the water. The live forecast above factors in that local effect, which is why you may see a slight temperature dip around 3–4 p.m. even before any showers arrive.
Why does the hourly forecast change throughout the day?
Environment Canada updates its models several times daily. As new satellite and radar data arrives, the timing of showers or wind shifts gets refined, so the live forecast above may adjust each hour.
When is the best time to be outdoors today?
Mid‑morning to early afternoon, before the showers develop, offers the most comfortable window. Check the live forecast above for the exact start time of precipitation in your neighbourhood.
Will the hourly weather affect evening plans?
Showers taper off by late afternoon, and clearing skies should make for a pleasant evening. Still, a jacket is handy as temperatures drop toward the low teens after sunset.
