Highest temperature in Toronto on August 12?

Platform comparison

Market context

Toronto's highest temperature on 12 August 2026 will be recorded at Pearson International Airport and settled against Weather Underground's Daily Observations table, the authoritative source for this market. The settlement window closes at midday UTC, meaning traders must account for the full calendar day's temperature swing before final resolution. Current crowd pricing sits at 0% YES across all temperature bands, indicating either extreme uncertainty about which range will validate or minimal deposit flow into this particular weather contract at present.

Historical August temperatures in Toronto cluster between 20–28°C for daily highs, with extremes occasionally breaching 30°C during heat waves. The 2021 Pacific Northwest heat dome saw Toronto reach 34.1°C on 20 June; August typically runs cooler than early summer peaks. Comparable weather markets on Polymarket show that seasonal temperature bands attract liquidity only when deposit rails—SEPA transfers, Klarna instalment payments, or USDC on-chain settlement—reduce friction for regional traders. The absence of visible YES probability here suggests book depth remains thin until funding inflows materialise.

Environment and Climate Change Canada publishes extended forecasts by mid-July; traders should monitor the 10–14 day outlook released around 1 August for any anomalous pressure systems or heat advisories. The North Atlantic Oscillation and jet stream positioning in early August will determine whether typical summer conditions or an Atlantic ridge drives temperatures upward. Deposit availability through Klarna's staggered payment schedules may unlock hedging demand if a heat event becomes forecast-certain in late July, shifting the probability curve sharply.

UK Frequently Asked Questions

What does SOFORT cost as a deposit method?
