Trader consensus on Polymarket implies a highest temperature around 9–10°C for Toronto on March 29, with 10°C or higher leading at 39.5% based on the latest Environment Canada forecasts showing above-seasonal highs from a persistent high-pressure ridge ushering mild southerly flow. Recent model runs from ECMWF and GFS ensembles, updated within the last 24 hours, maintain this warmth signal amid low confidence in late-winter variability, where historical March averages hover near 6–8°C but analogs support occasional spikes to 12°C+. Key uncertainties include potential cold frontal passages or cloud cover dampening daytime heating; watch for Environment Canada's noon forecast update and evening model refreshes, which could refine land surface conditions and boundary layer effects influencing peak temperatures.
