Cold nights forecast for London, Ontario this week

London Prepares for Temperature Drop

Residents of London, Ontario are advised to bundle up as meteorologists predict a significant temperature decrease in the coming days. According to CTV News London Meteorologist Julie Atchison, the region should expect a couple of cold nights on the way, marking one of the first substantial cold snaps of the season.

Weather Details and Timing

The cold weather system is expected to arrive following the recent publication date of November 13, 2025. While specific temperature readings weren't provided in the initial forecast, the warning indicates noticeably colder conditions than what Londoners have experienced recently. This seasonal shift aligns with typical November weather patterns for southwestern Ontario.

Regional Weather Context

The London forecast comes as other parts of Canada experience varied weather phenomena. Meanwhile, British Columbia's south coast faces heavy rain and coastal flooding warnings from Environment Canada. In Manitoba, meteorologists are monitoring a low-pressure system that could bring up to 20 cm of snow to certain regions.

Environment Canada typically issues such forecasts when temperatures are expected to drop significantly below seasonal averages, potentially posing risks to vulnerable populations and requiring residents to take winter precautions.

Preparation Recommendations

With colder nights approaching, London homeowners should consider:

  • Checking heating systems
  • Protecting outdoor pipes from freezing
  • Ensuring proper insulation in homes
  • Preparing emergency kits for vehicles

The timing serves as a reminder that winter weather preparation should be completed sooner rather than later across Ontario.
