Recent forecast models from Environment Canada and NOAA show Toronto’s daily high on May 17 hovering near 23–25 °C, with modest differences arising from cloud timing, lake-breeze effects off Lake Ontario, and the precise arrival of a weak frontal boundary. Ensemble guidance currently favors 24 °C as the most probable peak under mostly sunny afternoon conditions and light westerly flow, yet slight increases in morning stratus or stronger onshore winds could cap readings at 23 °C while faster clearing would support 25 °C. Historical May climatology places typical highs around 18–20 °C, so the elevated outlook reflects a brief warm-air advection episode that remains sensitive to small shifts in boundary-layer moisture and solar insolation. Updated model runs and official Environment Canada guidance expected overnight will likely tighten the range ahead of market resolution.

This market will resolve to the temperature range that contains the highest temperature recorded at the Toronto Pearson Intl Airport Station in degrees Celsius on 17 May '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Toronto Pearson Intl Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/ca/mississauga/CYYZ.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve to "Yes" until all data for this date has been finalized.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
