Recent hourly observations from Toronto stations, including Pearson and City Centre, indicate overnight cooling under mostly cloudy skies with northwest winds of 10-15 mph moderated the minimum near 10-11°C. Persistent cloud cover limited radiative cooling compared to clearer analogs, while urban heat effects and a moderating lake breeze kept readings from dipping further, aligning with climatological norms for mid-October. Trader consensus splits evenly between 10°C and 11°C because preliminary data and station-specific thresholds create uncertainty in the final official minimum, with model consensus and post-event verification expected to resolve the narrow gap.
