What is the Barrhaven forecast for today and tonight?

The live forecast above shows the afternoon high and overnight low. In spring, expect a mix of sun and cloud with a 30–40 % chance of showers as lake-effect bands drift north of the city. Winds from the northwest at 20–30 km/h will ease after sunset. For detailed timing, see the barrhaven weather hourly breakdown in Environment Canada’s regional outlook.

How does Barrhaven weather compare to Ottawa’s main station?

Barrhaven lies about 15 km southwest of downtown Ottawa, so temperatures are within 1–2 °C of the official Ottawa readings. However, the suburb’s lower building density means overnight lows can drop 2–3 °C faster on clear nights. For a broader picture, check our Ottawa weather page for city-wide trends and warnings.
