Recent forecasts from multiple models indicate a high near 22–24°C for Mexico City on September 14, aligning with the market’s emphasis on 23°C and 24°C outcomes. Persistent cloud cover, scattered showers, and moderate northeasterly winds associated with the ongoing rainy season are expected to limit solar heating at the city’s 2,240-meter elevation, keeping daytime maxima close to the September climatological average of roughly 23–24°C. Model consensus shows little day-to-day variability through the short term, with no strong warm-air advection or clear-sky periods projected to push readings to 26°C or above. Traders appear to be weighting the narrow historical distribution of September daily highs, where values cluster tightly between 22–25°C absent unusual synoptic forcing. Updated model runs and any late shifts in moisture or cloud timing ahead of the 14th remain the key near-term variables.
