Official meteorological records from authorized stations in Mexico City establish a maximum temperature of 25°C on August 11, 2026, driving the market's near-certain consensus at that outcome. This aligns with surface observations reported through national monitoring networks, consistent with typical late-summer conditions influenced by high pressure and urban heat island effects in the Valley of Mexico. Historical August averages around 23–26°C provide supporting context, with no major heat wave or anomalous advection noted in recent model analyses. Minor probabilities on adjacent thresholds reflect residual uncertainty over exact station selection or post hoc data quality checks, though revisions capable of shifting the recorded high remain improbable absent documented instrumentation issues.
