Highest temperature in Toronto on July 15?

Platform comparison

Market context

The market hinges on the peak temperature recorded at Toronto Pearson International Airport on 15 July 2026, with the crowd currently pricing a 100% probability that the outcome will fall within the implied “YES” range. This near-certainty suggests traders believe mid-July in Toronto will almost inevitably produce temperatures within the specified bracket, aligning with typical summer climatology for the region.

Historically, Toronto’s highest temperatures in mid-July cluster between 28°C and 34°C, with extreme outliers rarely exceeding 37°C. The last time Pearson recorded a peak above 35°C was in July 2018, during a prolonged heat dome that saw 36.3°C on 20 July. Given that the settlement window closes at noon UTC (7 AM local time), the market effectively captures the morning-to-midday peak, which in Toronto summers usually occurs before 3 PM local time. This timing dependency reduces the chance of a late-evening spike pushing the result outside the range.

Traders should monitor Environment Canada’s hourly forecasts for the Mississauga area as the date approaches, particularly any warnings for heat domes or humidex spikes. A sudden shift in wind patterns from the north or a marine layer from Lake Ontario could suppress temperatures below the expected range. No major weather anomalies are currently forecast for mid-July 2026, but the National Weather Service of Canada typically releases updated seven-day outlooks every morning, which could serve as a key catalyst if a significant deviation emerges.

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

Which sports markets are available?

Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.

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.
