Richmond Hill’s hourly forecast, based on the live data above, shows conditions shifting through the afternoon with lake breezes off Lake Ontario moderating temperatures near Yonge Street and Major Mackenzie Drive.
What does the hourly forecast look like today?
The live forecast above tracks hour-by-hour changes in temperature, cloud cover and precipitation chance across Richmond Hill. Inland neighbourhoods west of Bayview Avenue tend to see slightly warmer afternoon readings, while areas closer to the lake remain a degree or two cooler during the late morning. Wind direction flips from southerly to southwesterly after lunch, which can bring a brief dip in humidity.
How do lake effects influence Richmond Hill’s hourly weather?
Richmond Hill sits about 15 kilometres north of Lake Ontario, so onshore breezes often reach the town by mid-morning. This means the hourly temperature curve can flatten compared to places farther inland like Vaughan or Newmarket. Residents planning outdoor activities should check the live forecast above for sudden wind shifts, especially between 1 p.m. and 4 p.m.
How accurate are hourly forecasts for Richmond Hill?
Environment and Climate Change Canada’s hourly data is updated every hour and generally reliable for the next 12 to 24 hours. Beyond that, confidence falls, so check the Canada weather hub for longer trend summaries.
When does the wind pick up during the day?
Wind speeds typically increase around 11 a.m. as the lake breeze develops, then peak between 2 p.m. and 4 p.m. Gusts can reach 35 km/h near open fields north of Elgin Mills Road.
Can I rely on the hourly forecast for outdoor plans?
Yes for the next six hours, but always cross‑reference with the Toronto Weather page or the richmond hill weather 7 days outlook to catch late‑breaking changes.
