**Environment Canada’s official forecast for Toronto on August 5 calls for sunny conditions after morning fog, with a daytime high of 29°C and humidex reaching 35 under southerly flow.** This aligns closely with the market’s top outcomes clustered at 28–30°C. Regional model consensus and recent upper-level ridging have supported above-normal warmth for early August in southern Ontario, consistent with broader seasonal outlooks projecting temperatures 1°C above average in parts of the east. Short-term guidance shows limited variability in maximum temperatures, keeping extremes below 27°C or above 31°C at low implied probabilities. Updated model runs and any late-day observations will provide the final data for market resolution.
