Ottawa's spring is playing games again — after a warm stretch earlier this week, temperatures on Thursday are expected to drop to roughly half what they were on Tuesday, according to CTV News Ottawa. If you left your jacket at home midweek, you might want to dig it back out.
From Shirtsleeves to Sweaters in 48 Hours
That kind of rapid temperature swing is jarring, but it's also completely on-brand for an Ottawa spring. The capital sits at the crossroads of competing weather systems — warm, humid air pushing up from the south can send temperatures soaring one afternoon, only to be swept aside by a cold front rolling in from the north or west within a day or two.
Longtime Ottawans know this pattern well. One day you're eating lunch on a sunny patio on Elgin Street or strolling along the Rideau Canal in a t-shirt; the next, you're reaching for a toque and a winter coat. It's practically a local rite of spring.
What This Means for Your Week
If you have outdoor plans for Thursday — whether that's a lunchtime run along the Queensway pathway, a trip to the Byward Market, or a stroll through Gatineau Park — plan for noticeably cooler conditions. Layering is your best friend during Ottawa's shoulder season, when mornings can feel like March and afternoons can surprise you in either direction.
A few quick tips for riding out the swing:
- Check the hourly forecast before leaving — temperatures can shift several degrees throughout the day, especially with a cold wind off the Ottawa River
- Bring a light jacket even if it looks sunny — spring sunshine in Ottawa can be deceiving
- Don't pack away your winter gear just yet — the capital has been known to throw cold snaps all the way into late May
- Watch for gusty conditions — temperature drops in Ottawa often come with a wind shift that makes it feel even colder than the thermometer suggests
The Bigger Picture
The good news is that Ottawa's overall spring warming trend is well underway, and cold snaps like this one tend to be short-lived. By the weekend, conditions are generally expected to moderate — so patio season is very much still on the horizon.
Think of Thursday as a brief intermission, not a return to winter. Ottawa's warmer days are coming; this is just the city keeping you honest before you fully commit to putting the snow shovel away.
In the meantime, embrace the layers and chalk it up to one of the more endearing quirks of living in the capital — where no two spring days are ever quite the same.
