**Trader sentiment for Mexico City's October 15 maximum temperature centers on mild, stable conditions under increasing cloud cover and light precipitation that limit daytime heating.** Official forecasts from sources like the Met Office indicate a daytime high near 24°C amid overcast skies and drizzle chances up to 50%, consistent with the market's 45% implied probability for 24°C and 38.5% for 25°C. At 2,240 meters elevation, reduced solar insolation from persistent stratus and northeasterly flow suppresses peaks compared to clearer autumn days, while typical October baselines hover around 22–23°C. Model consensus on modest warming before midday showers explains the tight spread between leading outcomes, with lower probabilities assigned to 26°C+ reflecting low odds of significant clearing. Updated observations and afternoon model runs will refine resolution thresholds tied to official station readings.
