Current ensemble forecasts from agencies like the Met Office and regional models point to a Mexico City maximum temperature most likely between 23–25°C on August 8, shaped by typical midsummer conditions of partial cloud cover, scattered showers, and moderate easterly winds that limit peak heating. Differentiation among leading outcomes stems from model spread on precipitation timing and cloud thickness—earlier or heavier rain suppresses the high toward 23°C, while clearer intervals allow brief warming to 25°C or above—against a climatological baseline near 24°C. Traders are pricing this narrow range amid inherent short-range forecast uncertainty, with the next model runs and local observations likely to refine probabilities before resolution.
