Ottawa is set to kick off the weekend with truly spectacular weather, promising residents a delightful Friday and Saturday before a more varied pattern takes hold. If you're hoping for blue skies and warm temperatures, you're in luck for the next couple of days!
This Friday is shaping up to be a sun-drenched dream.
Expect perfectly clear skies throughout the day with a comfortable high of 21 degrees Celsius. While it's lovely weather, remember to be sun-smart; the UV index will be very high at 8, so don't forget your sunscreen, hats, and sunglasses if you're spending time outdoors. As evening approaches, the clear conditions will persist, with temperatures dipping to a cool 9 degrees Celsius overnight.
The good news continues into Saturday, offering another fantastic day to enjoy the outdoors.
The forecast predicts mainly sunny skies with the mercury climbing slightly higher to a pleasant 23 degrees Celsius. It's an ideal day for parks, patios, or any outdoor activities you've planned, making the most of the last full day of uninterrupted sunshine.
However, the weather pattern begins to shift as we head into Sunday.
While still warm with a high of 24 degrees Celsius, a mix of sun and clouds is expected to grace the skies. Keep an eye out for a chance of showers developing in the afternoon, hinting at the change in store for the new week.
Looking ahead to the start of the next week, the forecast indicates a noticeable increase in cloud cover and precipitation.
Monday is expected to be cloudy with a chance of showers, bringing the high down slightly to 21 degrees Celsius. This trend continues into Tuesday, which will also be cloudy with a chance of showers, and temperatures cooling further to 19 degrees Celsius.
Mid-week offers a glimmer of improvement, with Wednesday's forecast showing a mix of sun and clouds and a more comfortable high of 22 degrees Celsius.
Compared to the seasonal average for this time of year—which typically sees a high of 21 degrees and a low of 10 degrees—Ottawa is experiencing temperatures right in line with, or slightly above, what's expected, ensuring that even with the incoming rain, it won't be a cold washout.
