Honestly, if you've lived in the capital for more than a week, you know the drill. You check the forecast, see a number, and then realize the "real" weather is basically a completely different beast. Looking at the weather Ottawa Ontario 14 day outlook right now, we’re seeing a classic mid-January rollercoaster that’ll make your head spin faster than a skater on the Rideau Canal.
It’s January 17, 2026, and we are currently sitting in the aftermath of that massive dump of snow from Thursday.
The Immediate Reality Check
Right now, it’s about 11°F outside, but with that northeast wind at 9 mph, it actually feels more like -2°F. We’ve got light snow falling, and if you’re looking out the window, it’s that heavy, grey sky that just screams "stay inside with a beaver tail and a coffee."

People always think Ottawa weather is just "cold." That’s a total myth. It’s the humidity and the wind that actually get you. Today, the humidity is sitting at 86%. That’s the kind of damp cold that dives straight through your "winter-proof" parka and settles in your bones.
Weather Ottawa Ontario 14 Day: The Breakdown
If you're planning your life for the next two weeks, you need to be smart. We aren't just looking at a straight line of freezing temps. We have a weirdly "mild" peak happening today before the floor falls out again.
The Short Term (The "Warm" Spell)
Today, Saturday, we’re actually hitting a high of 32°F. In Ottawa terms, that’s practically a tropical vacation. We’re seeing snow showers throughout the day with about a 35% chance of precipitation. If you need to clear the driveway from the 25cm we just got, do it now. It’s going to get much harder once the deep freeze returns.
By tomorrow, Sunday, Jan 18, things start to slide. We’re looking at:
- High: 25°F
- Low: 6°F
- Condition: Light snow and flurries.
The Mid-Week Dip
Monday and Tuesday are where the "real" Ottawa shows up. We’re talking highs of 21°F on Monday dropping down to a brutal 9°F on Tuesday. And the lows? Tuesday night is hitting -9°F.
You've gotta remember that these are the base temperatures. Once you factor in the wind chill—especially with those southwest gusts—you’re looking at "exposed skin freezes in minutes" territory.

The Second Week Outlook
Looking further out toward the end of January, the pattern stays messy. We have periodic snow showers forecast for Wednesday (Jan 21) and Thursday (Jan 22). It’s that relentless "clipper" style weather where you get 2-5cm every single day. It’s not enough to cancel school, but it’s enough to make the 417 a nightmare every morning.
By the time we hit the weekend of Jan 24-25, the Polar Vortex starts flexing. We are looking at daytime highs that don't even break the zero mark. Saturday, Jan 24 is projected at a high of -2°F and a low of -18°F.
What No One Tells You About Ottawa Winters
Most people focus on the snow. The snow is actually the easy part. It’s the "flash freeze" that ruins your week.
When we have a day like today where it's near freezing (32°F), all that slush on the roads starts to melt. Then, when it drops to -7°F or -9°F on Monday and Tuesday, the entire city turns into a literal skating rink.

Pro Tip: If you see "Light Snow" on the weather Ottawa Ontario 14 day forecast followed by a temperature drop of more than 10 degrees, check your salt supply. Your front steps will be a deathtrap by 6:00 AM the next morning.
Is Winterlude Safe?
Winterlude kicks off Jan 30, right at the tail end of this 14-day window. The good news? The current cold snap is exactly what the National Capital Commission (NCC) needs to get the ice thick enough on the canal. After a few years of "will-they-won't-they" with the skating season, the sub-zero temps forecast for Jan 24-26 are a blessing for the ice carvers at Confederation Park.
Survival Steps for the Next 14 Days
Don't just look at the app and hope for the best.
- Hydrate your skin. This 14-day stretch has humidity levels jumping from 86% down to 57%. Your hands will crack faster than the ice on Dow's Lake.
- Layer, don't just "bulk." Tuesday's 9°F requires a base layer of merino wool. Don't rely on one giant coat; the air trapped between layers is what actually keeps you warm.
- Check your tires. With snow showers predicted for 8 of the next 10 days, those all-seasons aren't going to cut it on the side streets in Westboro or Orléans.
- Plan your outdoor time for the "Warm Windows." Today (Saturday) and Wednesday (Jan 21) are your best bets for being outside without your face hurting.
The weather Ottawa Ontario 14 day outlook shows a city in transition. We are moving out of a major storm and into a period of deep, biting Arctic air. Stay dry, keep your shovel handy, and maybe invest in some better mittens. You're gonna need 'em.
Actionable Insight: Clear your catch basins today while the temperature is near 32°F. If the melt from Thursday's storm pools and freezes during Tuesday’s -9°F dip, you’ll have a permanent ice block in your driveway for the rest of the month.
