Will the highest temperature in Toronto be 9°C on April 8?

“The forecast high of 8°C is only 1°C below the 9°C target, and weather forecasts issued even 24 hours out have typical accuracy margins of ±1-2°C, meaning 9°C falls squarely within the forecast uncertainty range.. Toronto's early April temperatures typically range from 7-9°C based on historical averages, making 9°C a climatologically normal outcome that sits at the upper end of the expected range for this time of year..”

“Multiple independent forecasting services (EaseWeather, Wisemeteo, Weather25) all converge on 8°C as the high for April 8 — this consensus within 24 hours of the event is structurally significant. Short-range forecasts (sub-24h) have substantially lower error variance than 3-5 day forecasts. The ±1-2°C accuracy range the bull cites is the FULL range, meaning the distribution is centered on 8°C, not uniformly spread across 7-10°C.. The resolution requires EXACTLY 9°C (i.e., the temperature falls in the 9°C bin, meaning ≥8.5°C and <9.5°C when rounded, or precisely 9°C depending on resolution rules). Even if the forecast is off by +1°C, the actual high could land at 8.5°C, 8.6°C, 8.7°C, 8.8°C, 8.9°C — none of which resolve YES if the market resolves on the integer 9. The bull conflates 'could reach 9°C' with 'will resolve YES at 9°C.'.”
