Forecast models from multiple agencies, including GFS and ECMWF runs referenced in recent Jinan Meteorological Bureau updates, indicate a high of 34–36 °C on August 25 under partly cloudy skies with only isolated showers possible. Persistent summer conditions, with recent observed maxima of 33–35 °C and no approaching frontal systems to bring cooler air, underpin the market-implied odds exceeding 99 % for 26 °C or higher. Official criteria rely on the city’s primary weather station readings, where afternoon peaks typically align closely with model consensus this close to the date. A realistic but low-probability shift could occur from an unforecasted localized downpour or measurement timing anomaly, though current atmospheric stability makes sub-26 °C outcomes highly unlikely.
