Pronóstico: Highest temperature in Toronto on August 12?

Platform comparison

Market context

Toronto's daily high temperature on 12 August 2026 will be measured at Pearson International Airport and resolved against the Daily Observations table on Weather Underground, with settlement occurring at midday UTC. The 0% crowd probability suggests traders expect temperatures to fall outside the upper range brackets available in this market, or that the current odds reflect uncertainty about which specific temperature band will resolve.

Historical August temperatures in Toronto cluster around 23–27°C for daily highs, with extremes occasionally reaching 30°C or above during heat waves. The city experienced a high of 31.4°C on 6 August 2023 and 30.9°C on 10 August 2022, establishing that late-summer heat events do occur but remain infrequent. Early August 2026 weather patterns and any Atlantic hurricane activity tracking northward will be the primary drivers; tropical systems occasionally push warm, moist air into southern Ontario and can elevate temperatures significantly above seasonal norms.

Traders should monitor Environment Canada's extended forecast for early August 2026 as the settlement date approaches, particularly any warnings for heat domes or high-pressure systems stalling over the region. The specific resolution methodology—using Daily Observations rather than the Day High & Low summary—matters operationally; discrepancies between the two sources have occurred historically, so confirmation of which data point Weather Underground publishes will be critical before final settlement.

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.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.

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.
