Get ready to bask in extended summer vibes, Ottawa! The National Capital Region is set to enjoy an exceptional start to autumn, with a glorious stretch of plus-20 degree Celsius weather expected to persist through the first full week of fall.
As the calendar officially turns to autumn, residents can anticipate a delightful forecast promising continued warmth and sunshine.
Environment and Climate Change Canada predicts temperatures well above the seasonal average, painting a picture of an Indian Summer extending deep into September.
Forecasters anticipate daily highs ranging from 20°C to 23°C for much of the upcoming week. This delightful pattern will kick off with Monday's forecast of 21°C under sunny skies.
Tuesday will see a slight bump to 22°C with a mix of sun and cloud, followed by a potential peak of 23°C on Wednesday, again with abundant sunshine.
Even as the week progresses, the pleasant conditions are expected to hold strong. Thursday and Friday are also forecast to reach 22°C and 20°C respectively, offering residents ample opportunity to enjoy outdoor activities without the usual chill of early fall.
This extended period of warmth is a welcome deviation from the typical seasonal transition.
While the long-range forecast hints at a slight dip towards the end of the week or into the weekend, with Saturday currently showing 18°C, the overall trend for the first seven days of autumn remains remarkably warm and inviting.
There's a minimal chance of precipitation, meaning clear skies and comfortable temperatures will largely dominate.
This fantastic start to fall provides the perfect opportunity to visit local parks, enjoy patio season, or take leisurely strolls along the Rideau Canal. So, pull out those light jackets and sunglasses, Ottawa, because autumn has arrived, and it's bringing some serious heat!
