Trader consensus on the lowest temperature in Toronto on August 27, 2026, centers on 18–19 °C because overnight observations at Toronto Pearson International Airport recorded a minimum near 19 °C under mostly clear skies following a daytime high of 26 °C. Northwesterly winds of 10–15 km/h promoted mixing that limited radiative cooling, while dew points near 14–15 °C constrained further drops despite low humidity. Model forecasts had projected lows of 15–17 °C, but actual conditions produced milder readings consistent with late-summer climatology for the region. The near-even split between the two leading outcomes reflects minor differences in station reporting times and urban heat-island influences that traders weigh against official Environment Canada data. Updated hourly observations near resolution will clarify whether the final minimum settles at 18 °C or 19 °C.

The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=cyyz
If NOAA data is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °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.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
