Highest temperature in Toronto on August 2?

Platform comparison

Market context

Toronto Pearson’s 2 August high will be set by the day’s late-morning and afternoon heating, with the market resolving on the *highest* temperature logged at the airport station rather than the forecast high alone. August in Toronto is usually warm rather than extreme, and forecast ranges for early August cluster around the mid-to-high 20s Celsius, which is consistent with long-run August averages and recent daily outlooks.[2][6][17]

That context makes the current 0% implied chance on a very hot outcome easier to read: Pearson’s August record highs have reached the upper 30s Celsius, but those levels are rare and usually require a strong heat plume and limited cloud cover.[9][13][19] In the broader Toronto record set, only a handful of August days have broken into the high 30s, so traders typically need a genuine heat advisory setup rather than an ordinary summer day for the top temperature to move into the extreme ranges.[9][13]

The key catalysts are the short-range forecast updates, any Environment Canada heat or humidity advisories, and whether cloud, showers or wind develop during the midday heating window, all of which can cap the maximum temperature at Pearson.[2][6][16] For market timing, note that the settlement window ends at 12:00 UTC, so the decisive reading is still likely to come from Toronto’s local daytime peak rather than the opening hours of the day.
