Highest temperature in Toronto on July 16?

Platform comparison

Market context

Toronto Pearson International Airport will record its peak temperature for 16 July 2026, with the market currently pricing the chance of any outcome above 27°C at zero. This 0% implied probability for higher ranges suggests traders expect a cool day, yet historical data from the same date last year shows an extreme heat warning issued when temperatures surged significantly, creating a stark contrast between current pricing and recent precedent [2]. The 42% probability assigned to “27°C or below” as the frontrunner indicates the book is heavily weighted toward mild conditions, despite the volatility typical of mid-summer in the region [1].

Traders monitoring this market must watch the daily weather schedules from The Weather Network and Wunderground, the official resolution source, for any sudden shifts in forecast models before the 12:00 UTC settlement deadline [3]. A recent public health advisory from July 2025 highlights how quickly Toronto can transition from mild to dangerous heat, making the timing of meteorological updates a critical catalyst for book depth [2]. Funding flows into this market are directly tied to payment friction; as Klarna and SEPA on-ramps reduce deposit fees, liquidity increases, allowing traders to react faster to these temperature dependencies and adjust positions before the window closes.
