Recent Environment Canada forecasts project sunny skies and a daytime high near 31°C for Toronto on May 18, driven by southwesterly flow and strong daytime heating ahead of a weak frontal boundary. This positions the 30–32°C range as the market focus, with closely matched probabilities reflecting typical model spread in peak timing and minor cloud variations that can shift the official maximum by 1–2°C at Pearson Airport. Historical May climatology shows highs in this range occur several times per decade under similar synoptic setups, while slight differences in surface wind or urban heat island effects further differentiate the leading outcomes. Updated model runs and final observations tomorrow will determine resolution.

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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
