Overview

• Temperatures are in the mid to high 20s across Toronto today, with the warm spell holding near 27 C through Monday.
• The highs are roughly 10–11 C above early-October norms, which typically sit between 15 C and 17 C.
• Environment and Climate Change Canada meteorologist Rob Kuhn says some areas could reach 27–30 C and Toronto’s daily records may be approached or broken.
• Rain is forecast Tuesday followed by a rapid cooldown, with highs near 22 C then the mid-teens by midweek and possible frost advisories later in the week.
• A three-day run above 25 C would rank among the warmest early-October stretches on record in the city, even as lake water remains cooler than the air for beachgoers.
