Ottawa residents have been doing a double-take at their thermostats this week, and for good reason — the capital is in the middle of a wild spring weather swing that has temperatures bouncing from a summery 25°C all the way down to a bone-chilling 2°C.
If you've been reaching for both your T-shirts and your winter coat in the same week, you're not imagining things. Ottawa's spring has taken a classic turn toward unpredictability, and meteorologists say the rollercoaster isn't over yet.
What's Going On With the Weather?
The dramatic temperature flip is being driven by competing air masses — a pattern that's pretty typical for Ottawa in April, when warm southern air and cold northern systems often clash right over the region. One day you're enjoying patio weather, the next you're scraping frost off your windshield.
The sharp drop from near-record spring warmth to low single digits caught many residents off guard, and the forecast isn't looking much more settled. More rain is expected to roll through the region in the coming days, adding a soggy layer to the already unsettled conditions.
Should You Pack Away the Winter Gear?
Not just yet. Ottawa's meteorological reputation for late-season cold snaps is well-earned, and this week is a good reminder that spring warmth can evaporate overnight. Gardeners, in particular, should hold off on putting out frost-sensitive plants until overnight lows are consistently above 5°C.
For commuters, the wet and cool conditions mean slippery sidewalks and slower travel times — especially on cycling paths that haven't fully dried out from earlier rain events.
How to Dress for Ottawa's Moody Spring
Layering is your best friend right now. Ottawa weather experts and seasoned locals know the drill: a light jacket in the morning, something waterproof for the afternoon, and always — always — check the hourly forecast before heading out for the evening.
The National Capital Region's geography, sitting in a river valley surrounded by the Canadian Shield and the St. Lawrence Lowlands, makes it especially susceptible to these rapid weather changes. Cold air funnels in from the north while warm fronts push up from the south, with Ottawa often caught right in the middle.
What's Coming Next
CityNews Ottawa is tracking more rain heading into the next few days, with temperatures expected to stay on the cooler side of seasonal norms before a potential return to warmer conditions later in the week. Residents are advised to keep rain gear accessible and to check Environment Canada's updated forecasts regularly.
For now, Ottawa is doing what it does best in spring: keeping everyone on their toes. Hold tight — patio season is still coming.
