Official forecasts from Environment Canada and supporting models project a sunny to partly cloudy day across Toronto on August 18, 2026, with a maximum temperature of 27–28°C under typical late-summer synoptic conditions featuring moderate high pressure and limited heat advection. These readings align with climatological normals for the period and recent model consensus showing no strong ridge or tropical moisture influx that could push values higher. Trader sentiment, reflected in the heavy weighting toward 27°C (61.5%) and 28°C (25.5%), tracks these authoritative projections while incorporating minor uncertainty from possible isolated showers or slight forecast revisions. Historical analogs for mid-August in southern Ontario rarely exceed 29°C without preceding warm-air advection, reinforcing the current market-implied distribution.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
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 18 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Toronto Pearson Intl Airport Station, 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 until the first data point for the following date has been published on the resolution source.
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.
