[Unusual Heat Wave in Early October]
London is experiencing an unusually hot stretch this weekend, with temperatures resembling mid-summer rather than early fall. The forecast predicts temperatures of 26°C on Friday, with a humidex of 27. Saturday will be a mix of sun and cloud, with morning fog patches clearing and a high of 28°C, feeling like 32°C with the humidex. Sunday and Monday are also forecast to reach 28°C.
[Reasons Behind the Warm Weather]
A strong high-pressure system over the United States’ East Coast is the primary cause, pumping warm air into the region. Environment Canada meteorologist Trudy Kidd explains that a large area of settled weather is parked there, funnelling warm air into southern Ontario. Clear skies in London are also contributing, allowing the sun to pack an extra punch.
[How Unusual is the Warm Spell?]
The hot spell is unusual for this time of year, with temperatures more typical of summer. While not unheard of, it serves as a reminder of the surprising weather patterns in southern Ontario and London, even as fall progresses. The coming weekend's temperatures do not align with typical expectations for this time of year.
