According to a new betting market listed on Polymarket, there is a 14% chance that Shanghai’s lowest temperature on July 13 will reach 31°C. This prediction is based on market speculation rather than official weather forecasts, and the actual temperature outcome remains uncertain.
The market was recently introduced on Polymarket, a platform where users bet on various events, including weather outcomes. The 14% probability reflects market participants’ expectations, not meteorological data from official sources like the China Meteorological Administration.
Weather forecasts for Shanghai around July 13 currently do not predict such high minimum temperatures. Experts say that a minimum temperature of 31°C would be unusually high for the city at night, typically experiencing lows around 25°C during summer nights. Learn more about Shanghai’s weather patterns. However, extreme heat events are becoming more frequent due to climate change, raising questions about future weather patterns.
It is important to note that betting markets are inherently speculative and do not serve as reliable indicators of actual weather conditions. Meteorological agencies have not issued any forecasts or warnings suggesting such high minimum temperatures for that date.
Implications of Betting Markets on Weather Predictions
This development highlights how betting platforms are increasingly used as alternative indicators of public perception about future events, including weather. While not scientifically reliable, such markets can influence public discourse and raise awareness about climate extremes. For residents and businesses in Shanghai, understanding the difference between speculative predictions and official forecasts is critical for planning and safety.

Shanghai Weather Patterns and Recent Climate Trends
Shanghai typically experiences summer nights with lows around 25°C, with occasional heatwaves pushing minimum temperatures higher. Recent years have seen more frequent and intense heatwaves, partly attributed to climate change. The city’s climate data from past summers show that a minimum of 31°C is highly unusual, though not impossible during extreme events.
Official weather forecasts issued by the China Meteorological Administration rely on meteorological models and data, and currently do not predict such high minimum temperatures for July 13. The introduction of betting markets predicting weather outcomes is a recent trend, but these are not substitutes for scientific forecasts.
„While extreme heat events are becoming more common, a minimum temperature of 31°C is highly unlikely based on current climate data and weather models.“
— Meteorologist Dr. Li Wei

Official forecasts from meteorological agencies do not indicate such high minimum temperatures for July 13. Weather outcomes depend on complex atmospheric factors that cannot be predicted through betting markets.

Key Questions
Is it likely that Shanghai’s lowest temperature will reach 31°C on July 13?
Based on current weather data and climate patterns, it is highly unlikely that the minimum temperature will reach 31°C. Official forecasts do not predict such extremes, and the betting market reflects speculative expectations rather than scientific analysis.
Why are betting markets predicting such a temperature?
Betting markets often reflect public perception, rumors, or speculation about future events. They are not based on scientific data and should be treated as entertainment rather than reliable forecasts.
Could climate change make such extreme minimum temperatures more common?
Climate change has increased the frequency of heatwaves and extreme weather events, but a minimum temperature of 31°C during summer nights remains highly unusual and would be considered an extreme scenario.
What should residents rely on for weather predictions?
Residents should follow official forecasts issued by the China Meteorological Administration or other authoritative meteorological agencies for accurate and reliable weather information.
