Mexico City's high elevation of roughly 2,240 meters keeps daytime highs moderate even in late June, with historical maxima clustering between 22°C and 27°C as the rainy season begins. Current forecasts from multiple sources point to 24–26°C peaks on June 22 amid increasing cloud cover and afternoon convective showers that limit solar heating and evaporative cooling. Trader consensus splitting evenly between 26°C and 27°C reflects minor model differences in timing of cloud build-up, humidity levels, and exact wind patterns rather than any extreme deviation. These factors create tight uncertainty around the upper end of the typical range, with lower probabilities assigned to 25°C or below if stronger storms develop earlier or to 28°C+ only under unusually clear, dry conditions.
