Persistent cloud cover, widespread rain, and elevated humidity from an active monsoon pattern are moderating overnight radiative cooling in Mexico City, keeping forecast lows clustered near 12–14 °C for August 23. Multiple model runs and observational guidance converge on this range, with light northerly winds limiting cold-air advection while high dew points near 13 °C suppress further drops. Trader sentiment remains split because small differences in cloud timing or precipitation intensity can shift the recorded minimum across the closely priced 15 °C, 14 °C, and sub-12 °C thresholds, and official station data will resolve the market once the daily minimum is confirmed.
