Highest temperature in Toronto on July 5?

Platform comparison

Market context

The real-world event is the daily peak temperature at Toronto Pearson International Airport on 5 July 2026, measured in degrees Celsius. Current crowd-implied probability for the 27°C outcome sits at 0% YES, yet historical data suggests this threshold is plausible. Average daily highs in Toronto during July cluster around 27°C, rarely dipping below 21°C or exceeding 32°C, with the month’s peak average reaching 27°C on 20 July [4][7]. Recent heatwaves across Canada in early July 2026 have already triggered flight delays and cancellations, indicating a warmer-than-average trend that could push temperatures toward the 27°C mark [10].

Traders should monitor Wunderground’s hourly updates for 5 July, as the resolution source is the highest temperature recorded at any time on that day [1]. Key catalysts include overnight low-pressure systems moving from the Great Lakes and any sudden shifts in wind direction that could trap heat near the airport. While no official weather service has issued a forecast for 5 July yet, the National Weather Service’s recent data from 3 July showed temperatures reaching 23°C by evening, hinting at a warming trajectory [2][5]. A sudden heat dome, similar to the one affecting the Eastern U.S. this week, could be the decisive factor [9].

What's the difference between match odds and outright odds?

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
