Live forecasts update automatically; written guidance last reviewed 16 June 2026 by the Canada Edition Weather Desk. Data from Environment and Climate Change Canada and other national met services via Open-Meteo.
Bolton’s current conditions are shown in the live forecast above. This community in Caledon, northwest of Toronto, sits inland near the Humber River valley, so temperatures here often run a degree or two cooler than the city and frost can linger later in spring.
What does the rest of the day look like for Bolton?
The live forecast above gives the hour-by-hour picture. For the broader trend, Bolton’s inland position means afternoon highs typically peak a little later than lakeside towns, and overnight lows can drop quickly under clear skies. If you’re planning outdoor work or a walk along the Humber, check the hourly details in that live feed — especially the wind direction, which can shift quickly through the valley.
How does Bolton’s location shape its weather?
Bolton sits on the Niagara Escarpment’s edge, about 50 kilometres northwest of Lake Ontario. That elevation — roughly 200 metres above sea level — gives it slightly more snow than Toronto in winter and a bit less fog in summer. The escarpment can also funnel winds, making conditions feel sharper than the thermometer suggests. For the most reliable local data, consult both the Environment Canada hourly product and the Toronto Weather page for regional context.
Does Bolton get lake-effect snow like Toronto?
Only indirectly. Bolton is too far inland to receive direct lake-effect bands from Lake Ontario, but when strong northwest winds push snow off Georgian Bay, the escarpment can enhance accumulations here.
Where can I find Bolton weather hourly from Environment Canada?
Environment Canada’s site offers a detailed hourly forecast for Caledon (Bolton). Search “bolton weather hourly environment canada” on their page, or use the live forecast above which draws from that same data.
Is AccuWeather reliable for Bolton?
