Temperature in Ottawa expected to drop Thursday

Residents of Canada's capital are being advised to bundle up as a notable cold front is set to sweep through the region. The temperature in Ottawa is expected to drop sharply on Thursday afternoon, marking a brisk change in conditions.

Forecast Details and Timing

The chill is anticipated to arrive during the afternoon hours of Thursday, December 4, 2025. This forecast follows a period of seasonal winter activity in the city, as evidenced by a snowman photographed in an Ottawa park earlier in the week on Monday, December 2, 2025. The sudden shift serves as a reminder of the unpredictable nature of winter weather in the National Capital Region.

Context of the Cold Snap

This incoming temperature drop is part of the broader winter pattern affecting Eastern Ontario. While the specific low temperatures were not detailed in the initial alert, the emphasis is on the rapid change expected during the day on Thursday. Such cold snaps can impact everything from commuting conditions to energy usage as furnaces work harder to keep homes and businesses warm.

Weather events like this often prompt city officials to issue reminders about frostbite prevention, the importance of winter tires, and checking on vulnerable neighbours during periods of extreme cold.

Preparing for the Chill

Ottawans are no strangers to cold weather, but rapid drops require quick adaptation. Experts typically recommend:

  • Layering clothing before heading outdoors.
  • Ensuring home heating systems are functioning properly.
  • Protecting pipes from potential freezing.
  • Keeping emergency kits in vehicles, including blankets and extra warm clothing.

Staying informed through local forecasts from sources like CTV News Ottawa is crucial for planning daily activities around these changing conditions. As the city prepares for this cooldown, it underscores the ongoing transition into the heart of the Canadian winter season.
