Check the live forecast above for Ottawa’s current conditions and today’s high, then plan around a mix of sun and cloud with a chance of a late-day shower. The capital sits where the Ottawa River meets the Rideau Canal, so lake-effect breezes and river valley shifts often keep temperatures a degree or two cooler than inland suburbs.
What will the temperature feel like this week?
Ottawa’s weather this week will stay seasonal, with daytime highs near the low mark shown in the live forecast above and overnight lows dropping into single digits. The humidity stays moderate, but a passing cold front midweek could bring a sharper wind off the Ottawa River. For a detailed look at the next two weeks, see our ottawa weather 14 day outlook.
Is rain or snow expected in the next 7 days?
No snow is in the immediate forecast, but a few rain showers are possible, especially Thursday afternoon. The ottawa weather 7 days page shows a drying trend heading into the weekend. If you’re heading out on the river or along the Rideau Canal trail, check the ottawa weather radar for real-time precipitation bands moving in from the west.
