Ottawa said goodbye to summer with a grey, foggy start on the final day of August, followed by a chance of showers rolling through the region. For a city that's spent the past few months chasing patio weather and canal-side sunshine, the shift felt like a preview of the cooler season ahead.
A Damp Farewell to August
Thick fog blanketed parts of the capital in the early hours, cutting visibility on some roads and delaying the usual clear-sky start Ottawans have gotten used to this summer. As the morning wore on, the fog gave way to a mix of cloud and the possibility of light showers moving through the National Capital Region. It's the kind of transitional weather day that tends to show up right around the seasonal turn, when warm, moist air lingering from summer collides with the first hints of autumn chill.
What It Means for Your Labour Day Weekend Plans
For Ottawa residents plotting out the long weekend ahead, a foggy, showery finish to August is a reminder to keep an umbrella within reach. Whether you're headed to the Ottawa Farmers' Market, catching a patio session on Elgin Street, or planning a last dip at Mooney's Bay before the unofficial end of swimming season, it's worth checking the hourly forecast before heading out. Showers moving through the region tend to be scattered rather than steady this time of year, so plans outdoors aren't necessarily off the table, just worth a backup option.
Ottawa's Seasonal Turn
Late August and early September in Ottawa often bring this kind of unsettled stretch: morning fog burning off into cloud, the occasional shower, and temperatures that dip just enough to make you reach for a light jacket in the evening. It's a far cry from the humid, sun-soaked days of July, and for many in the city it marks the unofficial signal that fall is on its way, even if the calendar still says summer for a few more weeks.
Gardeners and cyclists around the city have likely already noticed the shift. Morning fog rolling off the Ottawa River and Rideau Canal is a familiar late-summer sight, especially as water temperatures stay warmer than the cooling air above them. That contrast is often what drives the misty mornings the capital saw to close out the month.
Looking Ahead
As Ottawa heads into September, residents should expect more of this back-and-forth: warm, clear stretches mixed with cooler, damper days as the region settles into fall. It's a good moment to start thinking about swapping out summer gear for something a little more weather-ready, whether that's a rain jacket for the commute or a sweater for evening walks along the canal.
