Highest temperature in Shanghai on July 16?

Platform comparison

Market context

Shanghai is currently experiencing a wet, cloudy day with rain expected and a maximum temperature of just 36°C, a stark contrast to the scorching heat required for the market’s higher temperature brackets. The crowd-implied probability for the YES outcome sits at 0%, reflecting a consensus that today’s conditions will not produce record-breaking highs. However, historical data for mid-July in Shanghai often sees temperatures climbing well above 36°C, with the Polymarket frontrunner currently favouring 38°C at 46% probability, suggesting the 0% line may be mispricing the likelihood of a rapid heatwave before the settlement window closes at noon UTC.

Traders should monitor the shift from scattered afternoon showers to potential clear skies, as the weather forecast currently holds medium predictability and could pivot quickly if cloud cover breaks. The primary catalyst is the real-time temperature feed from Wunderground at the Pudong International Airport Station, which will determine the final resolution range. While current models show a low chance of a shower late morning, a sudden drop in humidity and wind speed could trigger a spike in temperature, creating a value spot for contrarian bets on the 37°C or 38°C ranges despite the current zero-implied probability.
