Forecast models and climatological data position 24–26°C as the most probable range for Mexico City’s July 16 high, aligning with the market’s concentration around 25°C (39.5%). The city’s high elevation (~2,240 m) produces moderate baseline temperatures, while the ongoing rainy season—historically the wettest month—brings frequent afternoon convection, cloud cover, and showers that limit daytime heating and cap extremes. Recent extended forecasts from multiple sources consistently show highs near 24°C with lows around 14°C, reflecting typical July conditions where mean maxima hover at 24°C and rarely exceed 26°C. Trader sentiment reflects this consensus, tempered by the inherent variability in convective timing and intensity that could nudge the daily peak slightly higher or lower. Updated model runs and official observations in the final 24 hours before resolution will provide the clearest signal for any late shifts.
