The current market odds of 25% for YES suggest traders collectively anticipate either cooler conditions or temperatures exceeding this specific threshold. This pricing likely reflects recent meteorological trends, seasonal forecast models, or market sentiment about incoming weather systems across South China. The market resolves using official daily maximum temperature records from Shenzhen's meteorological authority at UTC midnight on April 20. Prediction markets for local weather events provide transparent, real-time probability assessments that update as forecast models and actual conditions develop. Whether Shenzhen reaches 28°C as its daily high depends on cloud cover, atmospheric pressure, humidity levels, and broader regional weather patterns on that specific day.
