**Persistent rainy-season cloud cover and Mexico City's high elevation (around 2,240–2,300 m) are the dominant factors shaping overnight cooling, with official Servicio Meteorológico Nacional guidance and multiple model runs projecting a minimum of 12–14°C on August 24.** Recent observations confirm similar lows of 12–15°C amid widespread overcast skies and light rain that limit radiative heat loss, while recent August minima have already reached 12°C. These conditions, combined with light variable winds and high humidity, support trader emphasis on the 12–14°C range, though market-implied odds on cooler outcomes incorporate uncertainty in exact timing of clearing or localized topographic effects. Updated model consensus and any revised official bulletins ahead of the overnight period remain the key near-term catalysts.
